  • Dell E6400 Display issue - "doubling up" intermittently

    - by alex
    I've got a Dell E6400 It's suddenly developed an intermittent fault with the display Every now and again, it seems to boot up with "double vision" By that I mean, its split horizontally, with each half showing the same thing, but with low resolution, and looks grainy - if that makes sense (I will try to get a couple of pictures if I can) I haven't changed any hardware or anything. I have re-built windows, to see if that fixed the problem, it didn't. I've upgraded the BIOS to see if that would help, still same problem. I'm out of ideas :-(

  • XP shared folders not accessible after BIOS changed

    - by stijn
    Here's what worked for over a year: PC A runs Windows 7, PC B runs Windows XP. Both are on the same subnet behind a router. A uses user account X, but logs in to PC B using the Administrator account. PC B is a Dell Precision 470. A known problem with these is that sometimes when plugging in their power cable they somehow loses all BIOS settings. This happened yesterday. After this happens Windows won't boot, because the default BIOS setting is 'RAID ON' while there is no RAID configured. No problem though, changing the BIOS settings to 'RAID OFF' makes it boot without problems. Note that in the meantime, nothing config-related was changed on machine A. It wasn't even on. Indeed after doing this, everything is fine. Everything includes all normal operations, remote desktop from PC A to PC B, running Synergy between A and B, accessing shared folders from B to A. But accessing the shared folders on B from A does not work any more. I tried pretty much everything I found via Google (fiddling with policies/registry kes/...) but no avail. > ping -a 192.168.2.2 Pinging A [192.168.2.2] with 32 bytes of data: Reply from 192.168.2.2: bytes=32 time<1ms TTL=128 > net view \\192.168.2.2 System error 5 has occurred. Access is denied. > net use /persistent:no K: \\A\myshare /user:A\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:192.168.2.2\USERNAME PASSWORD > net use /persistent:no K: \\192.168.2.2\myshare /user:USERNAME PASSWORD System error 86 has occurred. The specified network password is not correct. A solution to this would be great: I haven't been able to do any work since yesterday ;] update after taking the hard drive out of B and putting it in another Precision 470 with almost exactly the same hardware (at first sight, only the video card differs) the shared folders work.. Putting the disk back into A, same problem remains. Why does this depend on hardware, and more important, on which hardware?

  • How to fix semaphore timeout period has expired.

    - by Ryan
    I bough a new hard drive and I'm attempting to copy stuff off the old hard drive to the new one. I tried it using Windows Vista and Windows 7 but no go. Then I tried installing some 3rd party updated drivers that were supposed to fix the problem now my Windows Vista disk won't boot. Has anyone had this problem before and how did you fix it?

  • Finding underlying cause of Window 7 Account corruption.

    - by Carl Jokl
    I have been having trouble with my Sister's computer which I built. It is running Windows 7 Ultimate x64. The problem is that I have had problems with the accounts becoming corrupted. First problems manifest themselves in the form of Windows saying the profile failed to be loaded properly and a temporary profile. Eventually the account will not allow login at all. An error message along the lines the authentication service failing the login. I have found information about this problem and how to fix it. The problem being that something has corrupted the account profile and backing up and recreating the accounts fixes the problem. I have been able to fix things and get logins working again but over the period of usually about a week it happens again. Bit by bit the accounts corrupt and then it is back to square one. I am frustrated because I don't know what the underlying cause of the problem is i.e. what is causing the accounts to be corrupted in the first place. At the moment I am just treating the symptoms. I was hoping someone who may have more experience with dealing with this problem might be able to help me find the root cause. Some articles suggest that Norton Internet Security is a big culprit of this problem which is installed. I could try uninstalling Norton and see if it helps. The one thing which is different about this computer to any other I have built is that it has a solid state drive. Actually it has both a hard drive and solid state drive. The documents and settings i.e. the Users directory is stored on the hard drive. This was done following an article about moving the user account data onto a separate drive on Windows 7 which I found on the Internet. Moving the User accounts is more of a pain under Windows 7 and this solution involved creating a low level file system link to the folder from the boot drive (Solid State) to the Hard Drive. The idea is that the computer behaves just as if it is accessing the User's folder from the boot drive but actually the data is stored on the hard drive. This may have nothing to do with the cause of the problem but due to the problem being user account corruption it is a possibility I have not been able to rule out. Any help would be appreciated as I would be glad to see the back of this problem.

  • Have Ubuntu auto-connect to wireless AP without logging in

    - by dragonmantank
    We have an ubuntu box set up to do some monitoring but due to the placement are unable to run CAT5 to the box itself. I have an Atheros PCI card that works great as long as someone is logged into Gnome and it doesn't disconnect from the AP during that time. Is there a way to have Ubuntu connect to the AP during boot, and always reconnect if it finds a signal from a specified AP? The box would have a static IP and only connecting to a specific AP using WEP.

  • How to get an inactive RAID device working again?

    - by Jonik
    After booting, my RAID1 device (/dev/md_d0 *) sometimes goes in some funny state and I cannot mount it. * Originally I created /dev/md0 but it has somehow changed itself into /dev/md_d0. # mount /opt mount: wrong fs type, bad option, bad superblock on /dev/md_d0, missing codepage or helper program, or other error (could this be the IDE device where you in fact use ide-scsi so that sr0 or sda or so is needed?) In some cases useful info is found in syslog - try dmesg | tail or so The RAID device appears to be inactive somehow: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md_d0 : inactive sda4[0](S) 241095104 blocks # mdadm --detail /dev/md_d0 mdadm: md device /dev/md_d0 does not appear to be active. Question is, how to make the device active again (using mdmadm, I presume)? (Other times it's alright (active) after boot, and I can mount it manually without problems. But it still won't mount automatically even though I have it in /etc/fstab: /dev/md_d0 /opt ext4 defaults 0 0 So a bonus question: what should I do to make the RAID device automatically mount at /opt at boot time?) This is an Ubuntu 9.10 workstation. Background info about my RAID setup in this question. Edit: My /etc/mdadm/mdadm.conf looks like this. I've never touched this file, at least by hand. # by default, scan all partitions (/proc/partitions) for MD superblocks. # alternatively, specify devices to scan, using wildcards if desired. DEVICE partitions # auto-create devices with Debian standard permissions CREATE owner=root group=disk mode=0660 auto=yes # automatically tag new arrays as belonging to the local system HOMEHOST <system> # instruct the monitoring daemon where to send mail alerts MAILADDR <my mail address> # definitions of existing MD arrays # This file was auto-generated on Wed, 27 Jan 2010 17:14:36 +0200 In /proc/partitions the last entry is md_d0 at least now, after reboot, when the device happens to be active again. (I'm not sure if it would be the same when it's inactive.) Resolution: as Jimmy Hedman suggested, I took the output of mdadm --examine --scan: ARRAY /dev/md0 level=raid1 num-devices=2 UUID=de8fbd92[...] and added it in /etc/mdadm/mdadm.conf, which seems to have fixed the main problem. After changing /etc/fstab to use /dev/md0 again (instead of /dev/md_d0), the RAID device also gets automatically mounted!

  • Windows 7 system drive says it is raw, but System Recovery starts without issues

    - by Iulian Chira
    I have been running Windows 7 RC1 since it was available a couple of months ago and had no issues whatsoever until today. When I start my laptop, Windows does not boot but instead Windows System Recovery starts. I've used diskpart to list the partitions on the drive and my system partition (c:) has a RAW filesystem. I really need to save all data on the disk as fast as I cant and I would really like not to have to reinstall my system.

  • Ubuntu 10.04 Lucid on IBM Thinkpad T41

    - by naugtur
    I tried to boot my T41 from a Ubuntu Lucid liveCD and it worried me. The white text on violet background had green pixels around it. After the splashscreen went away Ubuntu popped an alert that the installer had some errors and will now run live. The live system worked fine I guess... Did anybody experience such behaviour?

    - by ame
    Give me advice, please. My situation: There're the server HP ProLiant DL320e Gen8 and MegaRAID SAS 9261-8i RAID Controller. I installed Controller into server and I reconnected Mini-SAS cord from block of hard drives to controller, but I haven't any indication of hard discs on server front panel. There's indication of activity of drives only during boot of server. Controller has 2-pin connector (JT6B3, SAS Activity LED header) but where and how can I connect it? Thanx.

  • CPU Test Similar to Memtest?

    - by Nick Whaley
    I need an easy way to do system stability tests. I have come to rely on Prime95 which does a fantastic job of proving stability (or instability) very quickly; but it requires an OS installed. I would like something like Prime95 that stresses both CPU and RAM (maybe PCI-Ex bus also?) but runs in a nice bootable binary like Memtest86+ does, so I can boot it from a thumbdrive. Does such a thing exist?

  • System files not hidden Win XP

    - by ULTRA_POROV
    I recently copied my win xp install from one hard to another(via ubuntu live cd) Everything went well, except that all the hidden system files(boot.ini, ntdlr, io.sys) are no longer hidden. I tried this: attrib +s c:/IO.sys No effect. The files are still visible even though the setting to hide system files is checked. Any solutions? Thanks.

  • Linux ubuntu wubi

    - by Jamaica Bob
    I would like to install linux ubuntu next to my primary windows 7 OS. I found that wubi ubuntu installer which helps you with simple installation/uninstallation of ubuntu. But the wiki says that wubi uses a virtual disk. Is that similar to virtually running the OS? I really dont want my primary system to slow down because of that. Should i rather go with the classical dual boot? If WUBI, whats the recommended install size? Thanks

  • Software Raid 10 on VirtualBox?

    - by user791022
    I want to learn how to use Software Raid 10, is it possible to use VirtualBox by adding four storage images? This is my plan: 4x 100mb partitions (1 on each drive) configured as a raid 1 for /boot in ext3. Then with the remaining space on each drive, setup a software raid partition and configure it to to LVM and raid 10. In the LVM, set up a 4gb swap partition and the remaining space as the root partition ( / ) as ext3.

  • Unable to delete all partitions on flash drive using Windows 7 OS??

    - by irrational John
    Recently I purchased an ADATA C802 8GB flash drive. Since the drive was new I decided to run some of the HD Tune Pro (v4.50) performance tests on it, mostly just for the heck of it. To avoid accidently destroying data HD Tune refuses to write to a drive unless there are no partitions on the drive. If you do attempt to write to a drive with partitions, it posts the message "Writing is disabled. To enable writing please remove all partitions." As you would expect, the ADATA came formatted with a single primary FAT32 partition in the Master Boot Record. But a number of unexpected things happened when I attempted to delete that partition. The first thing I tried was to use the Windows 7 (64-bit) Disk Management tool (diskmgmt.msc) to delete the partition. It would not let me. The context menu choice to delete that volume was not available. Next I opened up a command prompt window with Admin authority and ran diskpart. Diskpart deleted the volume for me. However, when I attempted to run an HD Tune write test on the drive I still got the "Writing is disabled" message. Huh??? So I fired up a utility I have which allows viewing drives at the sector level and verified that the partition table in the Master Boot Record was empty. No partitions. Yet HD Tune still thought there were partitions on the drive? So why was I still getting the "Writing is disabled" message from HD Tune Pro? And why wouldn't the Windows 7 Disk Management tool let me change the partitions on this drive. After doing the above, I plugged the ADATA into my MacBook. I was then able to format it as either a GPT or MBR partitioned drive with no problems. I am not looking for suggestions on how to format this drive. I can do that. What I do not understand and was hoping I might get insight into is why this drive behaves so strangely under Windows 7? And BTW, what's up with HD Tune Pro? BTW, if I plug the drive I formatted on my MacBook back into my Windows 7 64-bit system I still run into road blocks with the Disk Management tool. For example, I cannot delete all the GPT partitions on the ADATA so I can convert it into an MBR drive. I following Microsoft's instructions, the instructions just do not work with this ADATA flash drive. Anyone know what's up with this? It makes no sense to me. Has something changed in Windows 7 (Vista)??

  • How to fix grub after moving root partition?

    - by Grzenio
    Hi, Because I am using one of the new WD disks I am trying to aling my root partition with the real sectors, as described here: http://community.wdc.com/t5/Desktop/Problem-with-WD-Advanced-Format-drive-in-LINUX-WD15EARS/m-p/10920#M631 So I copied all files to a temp location, deleted my partition (/dev/sda3), recreated it a few cylinders later (same name) and copied the files to the newly created partition. But now when I try to boot, I get my old grub menu but after selecting my kernel version it hangs... Any idea how I can fix it?
