  • DirectAdmin Centos4 server has virus

    - by Rogier21
    Hello all, I have a problem with a webserver that runs Centos4 with DirectAdmin. Since a few weeks some websites hosted on it are not redirecting on search engines properly, they are redirected to some malware site, resulting in a ban from google. Now I have used 3 virusscanners: ClamAV: Didn't find anything Bitdefender: Found a 2-3 files with JS infection, deleted them AVG: Finds lots of files, but doesn't have the option to clean! The virus that it finds is: JS/Redir JS/Dropper Still the strange thing is: website a (www.aa.com) does not have any infected files (have gone through all the files manually, is a custom PHP app, nothing special) but does still have the same virus. Website b (www.bb.com) does have the infected files as only one. I deleted all these files and suspended the account, but no luck, still the same error. I do get the log entries on the website from the searchengines so the DNS entries are not changed. But now I have gone through the httpd files but cannot find anything. Where can I start looking for this?

  • backup an existing linux server to a virtualbox virtual machine

    - by user146526
    I have some servers and VPSs to many companies across the world. I want to back them up locally. I have some backup solutions enabled to remote hosts, but I want to have a local backup on a computer at home. What I am thinking is: 1) Create a virtualbox virtual machine, install the same version linux as the server. 2) Use rsync to backup the server to the local virtualbox machine. (something like rsync -av --delete --progress --exclude '/dev/' --exclude '/proc/' root@server_ip:// / ) 3) Repeat the command every few days update files. 4) In case of a hard disk failure, or any other bad event, reverse the rsync command and get the files back and continue my bussiness. I tried it with 2 openvz VPS, the one was a backup of the other. I also tried to transfer normal linux server host to openvz machine and it worked great. That way looks pretty clean and easy to me, this is the kind of solution I am looking for. However I need to be sure that this will work if I am going to do it. The question is, will that work ok ? Does anyone see any problem with that ? Do you have any other suggestions ? Thanks

  • EC2 AMI won't boot after edit

    - by Eric Lars0n
    I did something stupid, I got a new laptop and copied everything over to the new one, then wiped the old one clean. Then I realized that I forgot to copy the private key out of .ssh that I use to connect to my AWS EBS backed instance. So I can't log in to my custom AMI. So I created a new Volume from the Snapshot of the AMI, then started up a public instance and attached the Volume to it, edit the sshd_config to allow for password log in. Unmounted the volume, detached it, made a snapshot of it, then made a new AMI from the snapshot. The new AMI launches, but never passes the Status Checks and is not reachable. What am I doing wrong? Or alternatively how can I fix my problem? Edit: Adding some of the console output Linux version 2.6.16-xenU ([email protected]) (gcc version 4.0.1 20050727 (Red Hat 4.0.1-5)) #1 SMP Mon May 28 03:41:49 SAST 2007 BIOS-provided physical RAM map: Xen: 0000000000000000 - 000000006a400000 (usable) 980MB HIGHMEM available. 727MB LOWMEM available.

  • Restoring a fresh home folder in a shared user domain environment

    - by Cocoabean
    I am using a tool called pGINA that adds another credential provider to my Windows 7 clients so we can authenticate campus users via campus LDAP. We have the default Windows credential providers setup to authenticate off of our Active Directory, but we have students in our classes that don't have entries in our AD, and we need to know who they are to allow them internet access. Once these LDAP users login using pGINA, they are all redirected to the same AD account, a 'kiosk' account with GPOs in place to prevent anything malicious. My concern is that my users will accidentally save personal login information or files in that shared profile, and another user may login later and have access to a previous user's Gmail account, as the AppData folder on each computer is shared by anyone logging into the kiosk user. I've looked into MS's 'roll-your-own' SteadyState but it didn't seem to have what I wanted. I tried to write a PS script to copy a pre-saved clean version of the profile from a network share, but I just kept running into issues with CredSSP delegation and accessing the share from the UNC path. Others have recommended something like DeepFreeze but I'd like to do it without 3rd party tools if possible.

  • SFTP, SCP, Secure Webdav: which is the most suitable ?

    - by Xavier Maillard
    Hi, currently, I am hosting a webdav share setup in order to store files I need anywhere I am. It is available via HTTPS. Things are that I do not need all the HTTP machinery -i.e. my nginx http server is only there for this webdav folder. I am not sure I made the best choice. My requirements on the client side are: secured transfers mountable as a network drive at work with 'near realtime sync' usable for any OS I could use (including my mobile (android)) At first, I chose webdav since it would pass through my work proxy (which refuses all that is not on HTTP/S (port 80 or 443)). Today, I am not satisfied with the setup and even if nginx memory footprint is pretty small, its webdav support is not really "clean" and full. What would you recommend between SFTP, SCP and the current webdav solution ? I think SFTP is the closest solution but I still have to find out how to pass through my proxy ;) SCP seems quite limited as I read about it (only file transfers if I read right). Cheers

  • Windows 7 BSOD, safe mode working,

    - by mil0ck
    I need help getting my dualboot with Windows 7 and Ubuntu 12.04 to work, and since I'm not to experienced with computers I've been pretty dumb. Here's what I've done, quite shortend though: First removed a Ubuntu 10.04 partion, and replaced bootloader using EasyBCD Installed Ubuntu 12.04 on same partion as before Decided I need more space so I shrinked my C: partion (Windows partion) using Here, after rebooting my computer, I was stuck a grub rescue, when booting up the computer I fixed that by using SuperGrubDisk Rescatux and then using my Windows Vista install disk to repair the computer (computer is using Windows 7) I know re-installed Ubuntu 12.04 on the linux partion and got the GRUB-bootloader working Then, after using my computer for several hours, I installed beta drivers (version 304.79) for my GeForce GTS 240 and then rebooted my computer. At the first boot (after reboot) my computer just crashed, and here I am When trying to boot Windows 7 now I get a Blue Screen Of Death. I can though boot in to safe mode with everything working. I have uninstalled the beta drivers and installed the same one as before but still the same problem. I have tried all the commands in Bootrec.exe and none is working. I can't neither find an OS when using Bootrec.exe/ScanOs. I have also tried running: sfc/scannow and that comes out clean. Short: My harddrive and files seems to be intact but when booting I get bluescreen. I can though boot in to safemode with everything working. I need help Thanks to anyone who even took the time to read that. //mil0ck

  • ASUS laptop doesn't charge/use the battery after reinstalling Windows 7

    - by Stan
    I've done a clean install of Windows 7 x64 on an ASUS X501A laptop. The battery is detected and shows in the system tray as "plugged in, charging". However the charge level stays at 76% and if the AC cord is plugged out the laptop turns off. The laptop does not turn on without being plugged in either. Everything worked perfectly prior to reinstall. I've tried: Downloading and installing all the ASUS drivers, including the ATK ACPI driver Checking the BIOS - there do not seem to be any battery-related settings Flashing the BIOS to the latest version Uninstalling Microsoft ACPI-Compliant Control Method Battery in device manager as suggested on the internet Full power discharge/ATX reset as suggested by ASUS support: remove mains power charger, remove battery, press and hold power button for 10 seconds, reconnect battery and mains and turn on I have a feeling all this may have something to do with the EFI BIOS that comes on the laptop. During the reinstall I had to delete all partitions and start anew, because the Windows installer complained about the improper order of GPT partitions. The EFI System Partition was recreated by the installer, and I am guessing that it may be missing the particular ACPI driver needed to make the battery work. I've tried researching this, but could not come up with any useful info. I am hoping someone here may know a bit more about this and maybe help me understand what's going on and how to fix it. Barring that, I'll have to re-image the drive off an identical ASUS laptop with stock install and hope it fixes things.

  • As an admin, what tools do you use to log what you do to your boxes?

    - by Jerry
    I am more of a linux applications developer than an admin. Over time, I've built servers and maintained them, sometimes to offer services, mostly just to develop the applications I work on. Way back when I would create a file in my account to keep notes on what I did on each machine, so that I could replicate that when I migrated to other machines. Nowadays, I install something a private trac installation, install it's blog plugin, and then use that to make notes of everything I install, and most commands that I run, as well as the output. This provides me a combination wiki and blog that I find very useful as a "captain's log". I do this mostly so that when I migrate to a new clean machine, I have a much easier time in bringing it up. And yet, I am always amazed when I see others just install this, delete that, run this, setup this config, ... without seeming to use any way to actually note what they are doing. What do YOU do, and what tools are available? I am especially interested in the transition between maintaining a few machines for a few people and maintaining several to dozens of machines providing a real service. What are the best practices, and where can I find good resources? Thanks!

  • Windows Server 2012 licensing issue preventing RDP connections?

    - by QF_Developer
    I am witnessing an unusual behaviour on 1 of 5 Windows Server 2012 R2 machines (clean install) that is preventing any remote connections from being established via RDP. I have run through the prerequisites for RDP here but I am finding that any remote connection attempt instantly stops the "Windows Protection Service". When I check the event logs I see the following entry. The Software Protection Service has stopped Event ID: 903 Source: Security-SPP From what I have read Security-SPP is tasked with enforcing activation and licensing, it appears that RDP requires this service to be in the running state. Is it possible that I have inadvertently activated this instance of Windows with a key that has already been associated to another instance (We have 5 keys as part of an MSDN subscription)? Would this be sufficient to block RDP access? When I look under System Properties (Windows Activation) it states that Windows is activated and there are no other obvious indicators that there's a licensing issue. EDIT 1: I ran a Powershell script to display the product keys for all servers in order to check for any duplication. For the problematic server I am getting the message The RPC server is unavailable.

  • Linux RAID: Replacing Failed Drive...permanantly

    - by user137519
    Okay, odd question here. I have a server with RAID 5. A drive failed, in a really physically in a really odd way. On the machine it boots and is seen by the BIOS but...no partition can be seen on the drive consistantly (in and out). 2 out of 3 drives working...I made new spare disk and added it, RAID 5 rebuilt clean. All appears well but...when I reboot it keeps trying to use the 2nd drive which doesn't give any partition data, so of course the RAID 5 gets 2 out of 3...again. The status of my drive is as follows: /dev/sda2:Good /dev/sdb2 (drive has physical problem so no partition data) bad, /dev/sdc2:good /dev/sdd2:good. Every time I reboot the mdadm system seems to keep trying to use /dev/sdb which has physical failure (although spins and is detected). /dev/sdd is the new drive I created. I added /dev/sdd to the raid and it rebuilds the raid but this action isn't memorized upon reboot so it keeps listing /dev/sda and /dev/sdc but doesn't use the perfectly good /dev/sdd until I re-add manually. I've tried removing the dead drive with the mdadm tool, but as it cannot see /dev/sdb paritions it will not fail or remove it (says partition doesn't exist). the /etc/mdadm.conf was automatically made on the original OS install which only lists: DEVICE partitions MAILADDR root ARRAY /dev/md2 super-minor=2 ARRAY /dev/md0 super-minor=0 ARRAY /dev/md1 super-minor=1 Basically just the raids to use on boot. I need to remove this semi-dead drive (/dev/sdb) but I'd prefer to know why this is happening before I do. any ideas or suggestions. I supposed I could attempt to clone/replace /dev/sdb (the partitions on drive show up, then disappear shortly after) but given the partition "chester cat" behaviour this seems risky to me and as I have a working "spare" it seems unnecessary. Thanks in advance for your insight.

  • Why is my cron daemon is being killed every few minutes?

    - by user113215
    As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6 x64 on an OpenVZ virtual machine. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has at least 800 MB of free memory, and cat /proc/loadavg returns 0.22 0.13 0.04 so resources shouldn't be the issue. With cron running, free -m reports: total used free shared buffers cached Mem: 1024 211 812 0 0 0 -/+ buffers/cache: 211 812 Swap: 0 0 0 I also tried removing and reinstalling the cron package using apt-get. Update: I initially thought the problem was a resource issues. I erased my entire VPS and started from a fresh Debian image. There is now nothing else running on the system, but even from a clean install my cron daemon is still being killed at random. What else should I check? How do I find out what's killing my crond?

  • Outlook 2010 - Missing New Mail Envelope Icon

    - by sdoca
    I've seen a number of posts related to this issue, but none with a solution that works for me. I have: Windows 7 Professional 64 bit Office/Outlook 2010 "Show an envelope icon in the taskbar" checked "Hide When Minmized" selected "Show icon and notifications" selected for Outlook in my taskbar settings This used to show me the envelope icon in my notifications area. Then something happened with my user profile and the sys admins created me a new one. Since then, the envelope only displays if Outlook is not minimized. It doesn't matter if I unselect "Hide When Minmized", the icon still doesn't display when new mail arrives. If I select "Display a Desktop Alert", then the icon is displayed. However, I HATE the desktop alert as I find it too intrusive/distracting. Is there some way to just get the envelope icon working (again)? UPDATE More testing and sometimes I will and sometimes I won't get an envelope icon with the desktop alert turned on. This is driving me nuts!! UPDATE TWO I like my notification area of the taskbar to be clean. So, all icons are set to "Only show notifications" except for Outlook as noted above. I've noticed the envelope icon is being displayed in the expanded notification area when I click on the up arrow to view all icons. So, it is being added to the notification area, but not displayed. It's a rather useless feature now...

  • Linux Centos 6 becomes unavailable from time to time - OS&network issue

    - by adoado0
    I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

  • My new SSD is causing issues. How can I solve them?

    - by Allan
    Computer specs 1 TB harddisc 120 GB 520intel SSD 8 GB DDR3 RAM Athlon Phenom II x64 955 3. 2ghz DK DFI Lanparty FX7900 M3H3 motherboard ASUS ATI RADEON HD6970 2 GB I have bought a new SSD (Intel 520, 120 GB), and wanted to use this as my system disc. I removed the other harddisc, and installed the SSD with the newest firmware. And then Windows 7 I updated Windows 7 with no problems and then put back my old harddrive. I formatted that old harddrive just to clean up at the same time... So at this stage everything was perfect. My new SSD was set as Master 0 Primary it boots on it and I have 1 TB emptyu harddrive I can use for whatever I want. So far no errors at all Now here is the problem, I installed a few games and everytime I tried to play the computer would say Windows must restart because DCOM server process launcher service terminated, or it says Windows must now restart because the Plug and Play service terminated unexpectedly Most commonly this error is caused by a rootkit virus, well I have tried formatting my entire computer, and running every antivirus I could find, so that shouldn't be it. I've also read somewhere it might happen when there are hardware issues. That on the otherhand would make sense, as I just put in a new SSD. I don't expect you to know this error. I haven't found anyone who knew it yet. maybe you can me guide through what might have gone wrong when I placed in the SSD? What have I checked regarding the SSD? It displays the right name when the computer starts up It has the newest firmware Did a 'sfc /scannow' which told me everything was fine I don't know what to do from here. Everything seems to work great with the drive. when I start playing games my computer crashes.

  • Can I disable the message line when launching ``screen -RR``

    - by Jimm Chen
    screen -RR is great. It does one of the two thing automatically: If there is any detached screen session, it picks up one can attach to it. If there is no detached screen session(no session yet, or all have been attach to other terminal), it creates a new screen session automatically. I use Windows server Remote Desktop a lot, screen -RR behaves almost the same when a client connects to a remote desktop server. It is natural and I like it. However, when screen -RR determines it should create a new session, it displays a message line at terminal bottom for 5 second. I'd like to suppress this message line because it brings us little benefit. In my opinion, a remote user can always easily distinguish whether he is connected to a resumed session(a piled-up display) or a newly created session(a clean display) from what he sees in the terminal window. So, is there a way to suppress the nag "New screen..." ? Just suppress that very one, not suppress message line globally. My env: opensuse 11.3, GNU screen 4.00.03 (FAU) 23-Oct-06

  • Win 7 firewall won't turn on, nor the McAfee firewall. Hit by "Win 7 Anti-virus 2012" trojan. Removed, but a downed firewall is a lasting legacy

    - by PhxTitan
    I caught the Trojan right away, I think, but both my McAfee & Win 7 (x64) firewalls are not able to be engaged/turned on now. MS Error Code 0x80070424 when attempting to turn on Win 7 firewall. No viruses. Swept it with McAfee AV, Malwarebytes Anti-Malware, Microsoft malware removal tools. Followed Microsoft's three courses of alternative actions they posted for instructions for getting the Win 7 firewall back up and on. Nothing. Same error code. The post just said see MS support if those fixes failed. So I removed McAfee altogether. Still Win 7 (professional version) firewall won't come on; and clean of detectable bugs. And I'm fully updated with MS Windows 7 updates as well, which is no longer automatic, that too a legacy of the trojan bug I think. Any thoughts on how to get the Win 7 firewall operational??? And auto updating reengaged?

  • nginx virtual hosts are not working, all vhosts goes to the default one

    - by Adirael
    Hello, I just did a clean install of nginx + php-fpm on a VPS running Ubuntu 10.10, nginx is serving and PHP is working fine, but I'm not able to add vhosts to it. Well, I can add them, but only one works, the rest go to this first one. This is my first vhost, for host1: server { listen 80; server_name host1; access_log /var/log/nginx/host1.log; error_log /var/log/nginx/host1.error.log; location / { root /var/www/vhosts/host1/; index index.html index.htm index.php; } location ~ \.php$ { include /etc/nginx/fastcgi_params; #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_param SCRIPT_FILENAME /var/www/vhosts/host1/$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_index index.php; } } And the second one, for host2: server { listen 80; server_name host2; access_log /var/log/nginx/host2.log; error_log /var/log/nginx/host2.error.log; location / { root /var/www/vhosts/host2/; index index.html index.htm index.php; } location ~ \.php$ { include /etc/nginx/fastcgi_params; #fastcgi_pass 127.0.0.1:9000; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_param SCRIPT_FILENAME /var/www/vhosts/host2/$fastcgi_script_name; fastcgi_param PATH_INFO $fastcgi_script_name; fastcgi_index index.php; } } The problem is, when I go to http://host1 everything is fine, but on http://host2, it just shows host1! I don't have Apache installed and everything comes from repos. Any pointers?

  • How to get back the themes feature in Windows XP?

    - by Martín M.
    When I try to set a visual style in Windows XP (the standard Luna, for example), I get one of these two: "Access denied" error. It works, but when I restart the computer, I get the Classic look again, with no errors. Also, the "Windows and icons" dropdown is grayed out in the "Appearance". This is a list of things I have tried, with no results: Making sure "Use visual styles on windows" is checked on System Properties Advanced Performance. Restarting the "Themes" service. It starts cleanly, no errors. Applying these two fixes: Kelly's Corner and tweaks.com. Running sfc /scannow and checking the integrity of uxtheme.dll against a clean installation of XP Restoring the whole \Windows\Resources\Themes directory. Creating a new user. The new user does not seem to suffer this problem. Maybe this is the solution, create a new user and migrating all the data, but it would be a pain, and I would prefer reinstalling the whole thing. I am using Windows XP Professional SP3, with no spyware, no virus, and no other visible malfunctions. How can I fix this?

  • Doesn't work Nginx + SSI

  • Is it possible to use rsync over sftp (without an ssh shell) ?

    - by Tom Feiner
    Rsync over ssh, works great every time. However, trying to rsync to a host which allows only sftp logins, but not ssh logins, provides the following error: rsync -av /source ssh user@remotehost:/target/ protocol version mismatch -- is your shell clean? (see the rsync man page for an explanation) rsync error: protocol incompatibility (code 2) at compat.c(171) [sender=3.0.6] Here's the relevant section from the rsync man page: This message is usually caused by your startup scripts or remote shell facility producing unwanted garbage on the stream that rsync is using for its transport. The way to diagnose this problem is to run your remote shell like this: ssh remotehost /bin/true > out.dat then look at out.dat. If everything is working correctly then out.dat should be a zero length file. If you are getting the above error from rsync then you will probably find that out.dat contains some text or data. Look at the contents and try to work out what is producing it. The most com- mon cause is incorrectly configured shell startup scripts (such as .cshrc or .profile) that contain output statements for non-interactive logins. Trying this on my system produced the following in out.dat: ssh-dummy-shell: Command not allowed. As I thought, the host is not allowing ssh logins. The following link shows that it is possible to accomplish this task using fuse with sshfs - however it is extremely slow, and not fit for production use. Is there any chance of getting rsync sftp to work?

  • What hardware would I need (approx) to run ESXi server?

    - by mr.b
    Hi, I am considering to purchase off-the-shelf commodity hardware in order to build server that will host virtual machines using ESXi server. Intended purpose for this server is NOT mission critical tasks. It will have to run perhaps 20-50 Windows XP/Vista/7 virtual machines (in total, but closer to 20 figure). Each guest would have to have 1-2 GB of ram, and probably two-three times more disk space than guest OS needs with clean install and all updates applied (that would be around 6-8 GB for XP, and i believe closer to 10-15 for win7). Those guests will act as a test ground for a new product that is network management software, thus guests will idle most of their time once initially loaded, but if I give them some task to complete, they should be able to perform reasonably well. Now, from what I have learned... CPU is usually not much of an issue (6 cores would do it), memory should not be lacking, but doesn't have to be sum of all guests, because of overcommitment... That leads me to IO, which is, as it seems, the bottleneck. Since I have very little experience with ESXi (and ESX, too) server, I'd like to ask: How much memory could I save by overcommitment, and how does it affect performance? Is 6-core cpu enough to run above described system? Would it be possible to run entire server off two (or even one) SSD drives (to host system virtual disks, with few additional HDDs (2-3) in RAID 0 to be used as secondary storage? I read somewhere that ESXi allows having something like "master image", essentially virtual machine that is "deployed" many times, so that disk space can be saved by having only differences stored by specific guests, instead of copying around whole virtual disks. Is this true, and how can this help me? Are there any other things I need to take into consideration when building this off-the-shelf solution? I should probably mention here that I'm fully aware of issues like SPOF regarding power supply, raid 0, etc, but since it's only a testing ground and not a production system, it's not so important for me. Thanks, B.

  • Hard drive causing BSOD

    I've come across a problem after building my new PC and installing a clean Windows 7. I originally planed on a RAID 1 or 0 but after further research I decided against it. So I was left with two 1TB Western Digital Black SATA 6Gb/s hard drives. My plan now was to use my second hard drive as a backup (using Windows Backup or 3rd party software). I set both hard drives to AHCI in the BIOS and installed Windows 7. I went through the lengthy process of downloading and installing each driver manually (latest versions), using the motherboard disk for a list of what I need. After a few restarts and before installing any software, I took an image backup onto DVD and the second hard drive. First witnessed the problem during the first scheduled Windows backup. The progress bar froze at about 70% (doc backup done, image backup in progress). It stayed still for 2 hours until it blue screened. Next time the backup froze, I tried shutting down. It logged me out and got stuck at the last step ("Shutting down" and blue spinner) for an hour, until I hard shutdown. I later realised this hasn't got anything to do with the backup. I ended up blue screening on almost every shut down (same place). Turns out, it's because of the second hard drive spinning down or turning off. The computer will now shutdown properly, as long as I remember to read or write to the second drive before executing shutdown. I've now set "Turn off hard disk after: Never" - No problems, so far. Do I have dodgy hard drive(s) or should I investigate the POWER_STATE_DRIVER_FAILURE BSOD - can it be a driver issue? AHCI?

  • Replaced CPU and black screen but no beep?

    - by luke
    I'm having a bit of trouble with a GIGABYTE GA-MA78G-DS3H (rev. 2.0) motherboard. Recently when trying to clean my AMD Phenom II X 4 CPU, I dropped it and broke some pins. I have now brought a Athlon 64 X2 5400+. However, it does not seem to work. To begin with, I cleared the CMOS via the jumper located near the battery. This was because I had my AMD Phenom II overclocked and did not wish for the same voltage to go to the new CPU. I then tried booting with the monitor plugged into the chipsets VGA but no luck. No signal was sent to the monitor, and the monitor just went into standby. I then tried it off the graphics card but the same happened again. Then I tried to check whether the CPU could executed some BIOS codes by stripping the RAM out and making sure a speaker was plugged in but no beeps could be heard. I replaced the speaker and tried again but no luck. The CPU is brand-new so what is going wrong?

  • No partition on USB Flash Drive?

    - by Skytunnel
    A friend gave me a corrupted USB memory stick to try recovery data from. But I've had some unusual results, so thought I'd share to see if anyone is familiar with this problem... First off I just tried opening from my own PC. Windows prompted to Format the drive, which I of course declined Downloaded TestDisk to anaylsis the drive. And right away I noticed something strange, on the listed drives it comes up as Disk /dev/sdc - 6144 B - USB Flash Drive That's right, the first USB flash drive smaller than a floppy disk!? Moving on anyway... first anaylsis comes up with: Partition sector doesn't have the endmark 0xAA55 TestDisk's Quick Search gave no results, moved on to Deeper Search: No partition found or selected for recovery This left me stumped. I tired a couple of other programs with no success I did manage to get a backup image, but it was just as small as TestDisk indicated, so nothing of use on it After a few hours trying various suggestions from other sources, I gave in and just tried formatting the drive. But returned the message: Windows was unable to complete the format. From googling that, the suggestion was to delete the partition. But there is no partition to delete in this case. most recently I've tried formatting from cmd, and got this result: Format D: /FS:FAT32 The type of the file system is RAW The new file system is FAT32 Verifying 0M 11 bad sectors were encountered during the format. These sectors cannot be guaranteed to have been cleaned The volume is too small for FAT32 Anyone got any suggestions? UPDATE: As per suggestion from @Karen, I tried running a CLEAN from DISKPART, results as follows DiskPart has encountered an error: The request could not be preformed because of an I/O device error.

  • Strange boot problems on 6 month old setup

    - by Balefire
    I've already exhausted my knowledge on this one, so forgive me if this post is a bit long. I built a computer 6 months ago for my wife and it worked fine until last week. Then it randomly shut down and would lock up while trying to boot on the boot screen. I cleared cmos and it allowed me to do startup recovery, but it "failed to fix the issue" so I reinstalled windows on the HD (moving the old install to windows_old). It worked, so I started installing drivers again, but then when I restarted to finalize installations it locked up again. This time, I took the hard drive and hooked it up to my computer, backed up all her files, and then formatted the hard drive before reinstalling it. (again had to clear cmos to let me boot from disk) It installed windows, I installed drivers, and it worked for a few hours but then died during startup again. So, then I got a new HD, cleared cmos, and installed clean again, with the same result as the time before, it worked for a few hours, installed windows updates, then crashed on the 3rd or 4th time turning it on. I decided next to try reinstalling and then going online to see if there were any updates for the BIOS or drivers on the Motherboard, but now I can't get it to even bring up the boot menu, so now I'm just left wondering was it the motherboard, or is it the CPU, or the RAM? The problem was strangely intermittent so I thought it had to be a software issue, since a hardware issue would ALWAYS fail to boot, right? But now it seems to be a hardware issue, because it's not bringing up anything. Any suggestions?
