• How do I connect to and factory reset a Catalyst 3560 Switch?

  - by Josh

  My company just bought another company. In their server room they had some older hardware, which I would like to repurpose. One of these is a Cisco Switch: C3560G-48TS-S. I found some instructions about this switch here but this is not a guide for a beginner. I have no idea how to connect to this thing to begin running the commands. It says Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. But I can't find anything on how to do this (assuming with telnet?) or even what program to use. I also don't know how to find the IP address of the device to connect to it. My research also says once I get in there, I need to run clear config all Is this the right command? Also, what if I can't get the username and password for these devices? Is there some way to factory reset (my only experience is with devices that have a hardware reset button) EDIT: I should note that when I push the button on the front the three lights blink, which according to the documentation indicated the switch is configured and "not available for express setup"

• Recovery disk Windows 8 HP Pavilion g6

  - by fpghost

  I recently purchased a HP Pavilion g6 laptop running Windows 8. I want to either obtain the Windows 8 ISO or make some kind of recovery disk that would allow me to restore the system if things go wrong. The HP Pavilion comes with the 'HP Recovery Manager' which I thought may do the job, but on running it and putting in a DVD-R as requested it seems to just hang for a number of hours without doing a thing (the disk sounds like it's spinning for a few minutes but then goes silent). I then tried 'recdisc.exe' but I get the error System Repair could not be created The device reported unexpected or invalid data for a command. (0xC0AA02FF) Next I obtained my Windows 8 product key using the software ProduKey thinking this would allow me to go to the Microsoft website and download the Windows 8 ISO, but as far as I can tell all that is available is the upgrade which can be used if one is running something like Windows 7. Can anyone advise? EDIT: after a reboot recdisc.exe did work; I think the problem was due to some Windows updates needing a reboot, but never the less I would like a full Windows 8 ISO if possible.

• How to recover Windows Password without reinstalling if you forgot Windows password?

  - by user38908

  Usually, we can recover Windows admin password in two traditional ways. The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example, 1 At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window. 2 Insert the password reset diskette into the computer and click Next. 3 If the correct diskette Windows XP will open a window prompting for the new password you wish to use. However, we offen ignore the important of security until we have been locked out of computer. Fortunately, there is still the last way that can unlock your computer without reinstalling - erase Windows password with Windows password reset CD, which can recover admin password for Windows 7/XP/Vista/NT/2000/2003.... Take Windows Password unlocker for example, followings are the steps to create the reset CD 1.Download Windows Password Unlocker from Password Unlocker Official site 2.Decompress the Windows password unlocker and note that there is an .ISO image file. Burn the image file onto an blank CD with the burner freely supported by Password Unlocker. 3.Insert the newly created CD into the locked computer and re-boot it from the CD drive. 4.After launched the CD, a window pop up with all your account names(if you have several accounts) select one of the accounts that you have forgotten its password to reset it. Just one press, this software can remove Windows password instantly.

• RDP suggesting a user name when connecting to a server

  - by Neolisk

  Prior to Event X, RDPing to Server 2003 always caused the user name appear blank and Login to be enabled, so you could pick to which domain you would log in. For us it's either local or our domain. Since a recent Event X a domain + user name is being suggested for every server and it's not the most recently used user name. If you remove it manually from RDP dialog, it's still being pre-populated for you, and then at the next available opportunity it returns into General/User name option of RDP dialog. So user name field comes pre-populated and you cannot change to log in locally (only if you manually erase domain specifier - everything before \) - Log in to option is disabled by default. We did not do any changes to our domain or client machines, so I am suspecting some Windows update caused it (and this being Event X). Interesting fact - it does not consistently happen on all machines, and some can login to some servers fine, while other servers keep suggesting a default user name. What could be that Event X and is there a way to fix it? EDIT: I tried this - How to clear remote desktop connections history and specifically this part of it: reg delete "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\UsernameHint" /f The problem still persists.

• Games on windows 8 in bootcamp lag even on lowest graphics

  - by Jackson Gariety

  I've been playing Crysis 2 and Skyrim on my Retina MacBookPro (10,1) for months now. The two games used to run super smoothly even on nearly maxed out settings. This laptop has an Nvidia GeForce GT 650M graphics card inside, it runs great. But I recently replaced my Windows 8 consumer preview with the retail copy, and since then, 3D games lag in this odd way, no matter what the graphics settings. Every second Skyrim and Crysis alternates between running smoothly and lagging. It's a cyclical lag that comes and goes like clockwork. I can turn the graphics down to 800x600 with no antialiasing and low texture quality, and it runs much smoother on the "up" motion of the cycle, but every second it moves back into this lag spike. I've tried installing beta graphics drivers, re installing the operating system, re installing the bootcamp support software, and freeing up space (I have about 20 GB free). I can't figure out what suddenly caused this other than some obscure difference between the consumer preview and the retail version. What can I try? Is my video card failing? Are there some other drivers I can install? This isn't normal lag from maxing out the card, it

• Should I buy more RAM for my computer or a better CPU?

  - by Reijer The Coder

  I have recently bought a new laptop, an ASUS N56VJ-S4149H. I bought it to use it in all possible ways I could want, so that would be gaming downloading and streaming movies browsing the web and programming software. So far it has been running great but one thing annoys me a little bit. I frequently play Mount&Blade: Warband, it's a great game and you should check it out. Everything runs smoothly but only when I turn down the 'Texture Detail'. Otherwise it will lag a lot and I can't really play. Now my question is: Is this a problem of not enough RAM? At first I was really sure it was but after thinking about for a while I'm not anymore. My computer only has 4 Gigabytes of RAM and there is still a slot open. So will it improve when I buy another 8 Gigabytes? EDIT: It has an Nvidia GeForce GT 635M inside. and an Intel Core i5 3230M CPU with 2,6 GHz. Help and answers are really appreciated. Thanks to all.

• How to set up a server without a hosting control panel

  - by A4J

  I have always used a control panel on my dedicated servers - from cPanel to Plesk to Virtualmin, and I am now considering ditching a CP altogether and manually editing config files. My requirements are fairly simple, I will host multiple sites on the server; some Apache with PHP & Mysql and some Passenger with Rails & Postgres. All will require email smtp/pop. FTP/Stats will not be required. Could someone please give me a quick run-down of what I would need to do - in terms of installing software and configuration? My server will come with a base install of CentOS 6.4 minimal. My thoughts so far: Install/update latest versions of MySQL & Postgres (are they 'safe' out of the box? Or do I need to do anything else like set up root passwords etc?) Install Apache & PHP (again, are the base installs good to go or do they require security tweaks?) Set up nameservers/hostnames/reverse DNS etc (Any guides on how to do this please?) Install Rubygems Install and configure Dovecot and Postfix (any tips on doing this? Or links to how-tos that cover it please?) Set up each website - any links to guides on how to do this? Install/configure firewall (or is the default install good to go?) Any other tips or advice would be greatly appreciated, as would links to guides or how-tos.

• Using multiple USB webcams in Linux

  - by rachelderp

  Running more than one USB webcam in Debian/Linux results in the the following error: libv4l2: error turning on stream: No space left on device VIDIOC_STREAMON: No space left on device What initially seemed to be a programming issue in OpenCV turned into a quest for a mysterious hardware/software problem after the same errors were produced by running cheese and xawtv. Apparently it's caused by webcams requesting all the available bandwidth on the USB host controller. With that in mind I decided to run wireshark and capinfos to see just how much bandwidth a single camera used. 4 megabits per second at 320x240 14 megabits per second at 640x480 32 megabits per second at 1920x1080 Interesting! That might explain why two cameras at 320x240 work but any higher resolution fails. It's as if my USB controller is only operating at USB 1 speeds, yet lsusb shows both webcams belonging to a device which supposedly supports 480 megabits per second. One solution proposed forcing the webcams to calculate their bandwidth usage instead of requesting their maximum by running the following commands: sudo rmmod uvcvideo sudo modprobe uvcvideo quirks=128 Unfortunately that made no difference, so I decided to try another solution. A post on StackOverflow suggested telling my webcams to use a lower FPS or compressed video format like MJPEG, but after running v4lctl list it doesn't appear either of my webcams support changing their video mode. And that's where I'm stuck. Why would two webcams operating well below the maximum speed of USB 2 would produce this error? ps: It's not a disk space issue, df displays no change when the webcams are started. pps: If it makes a difference, here's the output of lsusb

• Are there any benchmarks showing difference between hardware virtualisation enabled/disabled?

  - by Wil

  I have a 13" sub-laptop/large-netbook, it has an AMD Athlon Neo X2 L335, and I chose this one because it supports hardware virtualisation. In the end, I hardly do any virtualisation on it, however, when I do... it is fast. To my shock, I went in to the BIOS and saw that virtualisation was disabled! I turned this on and, I see no speed difference.... or at least none that I can tell. I do not have time to do a full set of benchmarks - and I run quite a bit of software on the host, so it wouldn't be scientific. I have searched quite a few places and I just can not find any benchmarks showing the difference of virtualisation bit enabled/disabled on the same hardware. Does anyone have any benchmarks they have seen that they can share? In addition, I know there was an uproar a while ago as Sony disable the hardware virtualisation on some models and only offer it in their higher models as a premium feature, however, apart from forcing an up-sell, are there any benefits to having it disabled e.g. battery/heat? I just can't find any information and can't work out why it would be disabled by default. Edit--- To add, The only thing I can find is that without it, you can not perform x64 virtualisation as fast. This is the only down side I can find. However, if this is the only difference, then I am still interested in the second part of the question - why offer the option to disable it?

  Here are my architecture : For the protected site 4 Host VSphere Enterprise Plus, each one with 2 HBAs FC connected to the switch fabric, connected to an EMC CX4-120 1 VCenter 1 SRM For the recovery site 2 Hosts Vsphere 4 1 Vcenter 1 SRM 1 CX-4-120 The CX4-120 is connected to the second CX4-120 with ISCSI and the MirrorView / Asynchronous. I synchronise for the time 6 Lun on a FC DAE, 2 on a S-ATA DAE I have allocated 30% of the amount synchronised LUN for the SNAPSHOT us, but I have allocated them only on my S-ATA II DAE. It does not make a problem, my snapshot are correctly active. All the installation is new (hardware and software), installed in January with the last files available in download. I have a strange problem, and it's random, sometimes when I run a test on my RP, some VMs have this error : Error: A specified parameter was not correct. I don't know where to look. Any help is appreciated... PS : I have checked on all the VMs, no Floppy disk or CD attached. PS2 : There is severals VMs with RDM and OCFS2 filesystems on it.

• Mail Server using Postfix

  - by unknown (google)

  I have currently set up my web application on Amazon EC2 server. As a well known fact sending email from EC2 has a problem. As a cheap and long lasting solution instead of using "authsmtp" is it possible to rent a server and use it as a Mail Server? I am currently looking for cheap hosting which will give me root access so that it can be configured and used as a relayhost. I am curently using Postfix as MTA. Has any one implemented this before? I am curious about its feasibility of this solution. I guess common requirements are: 1: Dedicated IP which is not black listed. 2: Open relay( open to my Server only) Any Tips for Header configurations to keep the mails out of spam folder. This is like exactly cloning authsmtp for personal use. Any suggestions for other Mail Server software instead of Postfix? Another problem is Reverse DNS for this server. Should PTR entry be present if a server is used as a relayhost?

• Low-profile, PCI Express, x1 video card with VGA-out?

  - by Dandy

  I just bought an Acer Aspire EasyStore H340 system (http://us.acer.com/acer/productv.do?LanguageISOCtxParam=en&kcond61e.c2att101=54825&sp=page16e&ctx2.c2att1=25&link=ln438e&CountryISOCtxParam=US&ctx1g.c2att92=450&ctx1.att21k=1&CRC=936243954) It comes with Windows Home Server, which I don't particularly care for (too dumbed down for my liking)--I bought the box mainly for the form factor, and intend to install Server 2008 on it and have it run as a small domain controller. The geniuses at Acer however went out of their way to ensure you can only run Home Server--you can only connect to it via the Home Server Connector software, as it has no video-out whatsoever (so essentially, there's no way to even get into the BIOS). It only has a low-profile, PCI Express x1 slot. It turns out to be way harder than I thought to locate a video card that both has an x1 connector, and is low-profile (I'd really rather not snip the bracket at the back just so it'll fit the case). I know they're out there, and I've seen one with Display Port outputs, but I don't have a monitor with this connection. So to reiterate, it needs to be: - x1 connector - low profile - VGA out (though DVI would be okay; I have some spare adapters) Can anyone recommend anything at all?

• Apache https is slow

  - by raucous12

  Hey, I've set apache up to use SSL with a self signed certificate. With https (KeepAlive on), I can get over 3000 requests per second. However, with https (KeepAlive off), I can only get 13 requests per second. I know there is supposed to be a bit of an overhead, but this seems abnormal.

• How to Monitor Network in Medium-Sized Company?

  - by Kyle Lowry

  I work at a medium sized company (100+ employees). An issue that has been cropping up is network performance, internet access in particular. We have about 70 or more computers, a mix of Mac OS X and Windows XP & 7 machines. We have several servers (Exchange server, PC file servers, MS SQL, Blackberry, FTP, Mac server, etc). There are four main switches, a SonicWall firewall, and probably a couple routers in the server room with a dozen or so more scattered around the building. The network structure has grown organically over a number of years; and, as far as I know, there really isn't a monitoring solution in place. When we experience network issues (slow connections, dropped packets, and so on), our general solution is to power cycle some hardware or go around to each employee and ask them if they are uploading/downloading any large files. This is really inefficient and time consuming, and it does not allow us to monitor the network, tackling potential problems proactively. I would like to find a solution that would allow me to monitor network usage company-wide in real time, with detail going down to the individual computer, ideally. Given the hodgepodge of equipment and operating systems, what would be the best way to set up some kind of monitoring solution? Hardware, software, restructuring our network architecture?

• Datastage 8.7 installs fine on Window7 without any errors but it can not launch localhost:9080 web console

  - by user265273

  When I launch the web console, I get page can not be displayed error. What I have tried so far: I have re-installed DS about 7 times, and each time, I get same errors. I added entries in etc/hosts file for local host and my host name. I have turned off firewall. My hardware/software setup. My host system is window8.1. My vmware workstation is 7. The guest os is windows 7 enterprise x64. I have installed 10g, and given dba role to public. I have installed VS 5, and ms visual c++ 2010 express. I have installed msxml. IE version is 10. Firewall is off. My internet works fine It passed all the DS requirement tests and install completed successfully. When I launch my vmware guest instance, I do get SQL5000c error upon boot which I have tried to ignore in some installs and in some, I used db2systray -clean command to get rid of it. But that has not helped solve the webconsole connect failure to my host. I have spent over 2 weeks exclusively on this issue and badly need some help.

• How can I take browser screenshots at a higher resolution than my browser supports?

  - by user53575

  I need to take a screenshot of a website as it would appear on a very high resolution monitor... say 16000x12800 pixels. My laptop's screen has a native resolution of 1280x800. Basically, I need to simulate having a monitor resolution much higher than my monitor and video card actually supports. I want the screenshot of the site to look pretty much how it does when you hit CTRL MINUS (zoom out) in Firefox repeatedly, but without any loss of pixels due to scaling. How can I do this? Is there some way to use virtual machine software to simulate a super-high-res display? If not, is there some way to open a browser window bigger than the screen, and then capture its contents as a PNG somehow? Anything else that might work? Here was an answer: http://superuser.com/questions/120266/how-can-i-take-browser-screenshots-at-a-higher-resolution-than-my-browser-support But it doesn't work. Firefox remains in the resolution of the physical screen. The window blinks and shrinks back to normal resolution. Please Help!!

• Upgrade to Q9550 or i7 920 on a budget?

  - by evan

  I'm planning to upgrade my computer and torn between maxing out the system I have or investing in the X58 architecture. I'm currently using a E6600 Core 2 Duo with 4GB of RAM (800mhz) on an Asus PK5-E motherboard which I built two years ago. My original plan was that one day I'd upgrade machine to 8GB (1066mhz, the max the PK5-E allows) and to the Core 2 QuadQ9550 to give the machine a good four years of life. However, that was before the i7 came out. I use my computer mainly for software development , which I do inside Virtual Machines, and the i7 seems ideal for that because it no longer is limited by the speed of the FSB? And when I looked into it, getting 8GB DDR3 RAM isn't much more expensive than the 8GB of DDR2 and the i7 920 is comparable in price to the Q9550, which doesn't make much sense to me? So the question is it worth swapping the motherboard out for around $250 and upgrading all three components or using that money on SSD or 10rpm drive for the existing system's OS/Apps/Virtual Machine drive? Or just put the $250 towards a completely new machine in a year or two? Would the i7 really give that much of boost compared to the Q9550 for what I'd be using it for? Thanks in advance for your input!!!

• Why is my new PC so slow at startup?

  - by rumtscho

  Bought a new PC this weekend, and it works really good. Only I have one big problem: startup time. Its BIOS needs 62 sec to load, then from Grub start to pw entering screen it's another 26 sec. I think this is a lot, because my old PC needs 34 sec for BIOS and another 8 sec to pw screen. After I enter the pw, the desktop is usable with practically no delay on both. The new PC is a core i7-930, running a Lucid Lynx 64 bit from a Intel Postville SSD (no internal HDs). The old PC is a Pentium 4 celeron (forgot the clock speed) running a Lucid Lynx 32 bit from an ATA 100 hard drive. Neither PC is overclocked. The new one has boot sequence 1.DVD ROM, 2.SSD (connected over SATA in AHCI mode), 3. removable drive. The old one boots from 1. DVD ROM, 2. HDD, 3. Floppy. Neither has a second OS installed. The new one has less software installed than the old one (I think), but the boot time difference was noticeable even before I made any installs. As far as I know, just the SSD should be enough to make a noticeable difference in boot time. I thought that having a good mainboard on the new PC as opposed to the basic office model on the old one would also mean a faster loading BIOS. If these assumptions are right, I guess I must have misconfigured something in the BIOS of the new PC. How should I configure it for a fast boot? It has an ASUS P6X58D board with an AMI BIOS, if you need the BIOS revision number I could post that too.

• What tools can I use to locate the IP of a machine on my network?

  - by user134918

  I am logged in to a remote Windows Server machine and am trying to attach it to a VPN for a LAN that I am also connected to locally from another Windows machine using Remotr Desktop. I can connect the remote machine to the VPN but when I do so, I lose my remote desktop connection. I am now in a situation where I know/think that the remote machine is on my LAN, but do not know what its current IP is and can therefor not connect to it again. I do not have any control over the infrastructure, all I have is a remote machine that I do control, and another machine that I also control that is connected to the same LAN as I'm trying to get the remote machine on using the existing VPN. What tools are available for Windows to allow me to locate the machine on my LAN again? I am imagining that there must be a tool that broadcasts the machines new IP using multicast, or tries to log in to a server component running somewhere with a know IP. Effectively, I am looking for some software that I can run on my remote machine, as well as my local machine, to allow me to discover the new IP address (on the LAN) assigned to the remote machine after connecting to the VPN.

• How do I install Apache Portable Runtime?

  - by apache

  My Apache is installed by yum install apache And now I'm trying to install subversion server from source following instructions here. But when I try to configure,get an error: [root@vps303 subversion-1.6.9]# ./configure configure: Configuring Subversion 1.6.9 configure: creating config.nice checking for gcc... gcc checking for C compiler default output file name... a.out checking whether the C compiler works... yes ... checking for APR... no configure: WARNING: APR not found The Apache Portable Runtime (APR) library cannot be found. Please install APR on this system and supply the appropriate --with-apr option to 'configure' or get it with SVN and put it in a subdirectory of this source: svn co \ http://svn.apache.org/repos/asf/apr/apr/branches/1.2.x \ apr Run that right here in the top level of the Subversion tree. Afterwards, run apr/buildconf in that subdirectory and then run configure again here. Whichever of the above you do, you probably need to do something similar for apr-util, either providing both --with-apr and --with-apr-util to 'configure', or getting both from SVN with: svn co \ http://svn.apache.org/repos/asf/apr/apr-util/branches/1.2.x \ apr-util configure: error: no suitable apr found How do I get around this problem? BTW,will both client and server software be installed by compiling from source?

• mail server checklist..

  - by Jeff

  currently we ran into some issues with our mail server setup. im preparing a list of actions that we should enforce and use in order to maintain a proper email solution within our company. we have around 80 exchange users, and send mass emails out almost on a monthly bases to 20,000 + customers each time.. the checklist i currently have: 1) mcafee mxlogic 'cloud' anti-spam functionality for incoming message. 2) antivirus on each computer in company 3) antivirus on exchange and DNS servers 4) setup SPF record 5) setup DKIM 6) setup domainkey 7) setup senderID 8) submit spf to microsoft, yahoo, etc. for 'whitelist' purposes. 9) configure size limits for messages in exchange to safe numbers 10) i have 2 outside IPs for my email server, incase one gets blacklisted, switch to the backup. 11) my internet site rests on a different ip than the mail server 12) all mass emails for company sent through 3rd party company (listtrak.com) 13) setup domain alias, media, enews, and bounce for the 3rd party mass mail software. 14) verify the setup using [email protected] 15) configure group policy and our opendns.org account to prevent unwanted actions and website viewing mass emails: 1) schedule them to send different amounts at different times (1,000 at 10am, 1,000 at 4pm, 1,000 10am next day).. 2) setup user prefences, decide what they want to receive ect. ( there interests) 3) send a more steady flow of email, maybe 100 a week with top new products instead of 20,000k every other month.. if anyone has suggestions or additions/subtractions to this checklist they are greatly appreciated. thank you

• Despeckle line art

  - by Dour High Arch

  We have a number of line-art charts unfortunately saved as JPEGs. They are now riddled with distracting compression artifacts or "speckles". Is there any way of removing these? I do not have the original files and it will be very difficult to recreate them. I am running Windows 7 and tried Paint.Net; none of the filters help. Posterize washed out all the colors and leaves the speckles. Blur makes text unreadable. Noise Reduction wrecks antialiasing of curved lines, and perversely enhances the speckles, making them look like checkerboards. Yes, I have Googled for software to do this; there are many programs that advertise despeckling but, after my experience with Paint.Net, do not want to experiment with applications that show no before and after images. The only example I have seen that does what I want is from a Photoshop tutorial. I have dozens of files and the tutorial requires considerable manual fine-tuning. I would prefer to automate or batch-process this task. Commercial apps are fine, but I do not want to spend over $600 and learning a complex program for a single task.

• zsh : How to list directory content with tab?

  - by Philippe CM

  I just switched from BASH to ZSH and thing are pretty good, but: when I start typing cd /usr/share/s and hit TAB, this is what I get : $ cd /usr/share/sane/ sane/ skype/ ssl-cert/ screen/ smplayer/ strigi/ seed-gtk3/ snmp/ synaptic/ sgml/ software-properties/ system-config-printer/ sgml-base/ soprano/ sysv-rc/ sgml-data/ sounds/ simple-scan/ splashy/ And this is ok. If I then hit TAB again, I get $ cd /usr/share/screen/, the next candidate, witch is also OK. (BTW, how do I cycle back to the previous candidate? Sorry, on to my question) Now what if I want to see the contents of /usr/share/screen/ now ? You now, BASH-style? The cursor is at the end of the line, will I have to ctrl-a (or home), then del del (to erase cd) then ls then ENTER? That seems like a lot of typing. (And it - possibly unnecessarily - enters the command in the history) Would not there be a key (maybe modifier-TAB? but the obvious candidates are already taken by the desktop... I digress) that would tell zsh to stop cycling through /usr/share/ and instead, just list the content /usr/share/screen/ ?

• Ubuntu 10.10 - PC shutdown before boot shortly after BIOS loads

  Hi - Since installing Ubuntu 10.10 from Karmic I've started getting problems with starting up the PC. I've done a complete wipe (Boot and Nuke) of the hard drive and reinstalled Ubuntu 10.10 but the problem still occurs. There is no dual boot on the PC, just Ubuntu. Here is the problem: Each morning, when I turn the PC on from being off overnight, the PC starts up and loads the BIOS. I get the following message : "Verifying DMI Pool Data... K8 NPT Data Change...Update New Data to DMI!....... Then poof the computer shuts off. However, after switching the computer back on around 6 or 7 times after it's turned itself off, it will eventually boot up without any problem. Also, once up and running for a while, I can shutdown and restart the PC first time, without any issues. I have also noticed a problem with the USB mouse being recognised and once I finally get the computer booted up, I need to unplug and then plug the mouse back in to get it working. I've opened the PC up and checked the connections (cables, cards and memory) and it all seems fine. The main issue with troubleshooting this problem is I cannot test any suggestions or fixes until the next morning because once the computer is up and running it will remain so! I do not leave the computer on overnight to save energy. So.. is this a hardware / boot software issue? This is a very odd problem and I have googled to no avail. Any suggestions? Many thanks Clem

• Where does Windows store MSI files for uninstallation?

  - by Nilzor

  I'm trying to figure out how Windows (XP through 7) is handling installation and uninstallation of MSI files. I have come up in situations where Windows Installer is unable to uninstall because it's missing the original MSI file, which leads me to believe that it stores a copy of all installed MSI packages somewhere. Where? I've had a couple of theories. It expectes it to reside in the same folder as it was installed from. The registry keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall does point to the original installation folder, and error messages when the MSI file is missing often point to this. Removing the MSI file from this folder does not hinder the uninstallation process though, so I've refused this theory. C:\Windows\Installer. This folder actually contains a bunch of seemingly randomly named MSI files. But this list is incomplete. I do find entries in the registry key mentioned in 1) which does not have an MSI copy in this folder. So how does this work? How is windows installer able to uninstall MSI-installed applications even though the MSI is not in 1) and not in 2)?
