Hello. My computer kept restarting. I came down to it this morning and I tried to launch an application, but it failed to start. I decided to restart the computer. When it came to the welcome screen, I clicked my name, but then without warning the computer restarted. As windows booted up for the second time, before getting to the welcome screen it went to a BSOD telling me "A problem has been detected and windows has been shut down to prevent damage to your computer". I don't remember the rest of the message but it said that it was dumping the contents of memory to disk. A timer ticked as it did this. Once that was finished, the computer shut down.
I then tried to boot into safe mode. I could do this and logged in sucesfully as "Administrator". Wondering if the problem had sorted itself, I logged out and then in as my regular account. A few moments after doing this the computer rebooted without warning.
Next I tried to use the Windows XP install disk to repair the system. I booted from the disk and selected the "repair" option. It scanned the disk for a while and then restarted.
I tried the install disk again, this time it gave me another BSOD. The message was different this time. I copied it down fully:

IF this is the first time you've seen this Stop error screen restart your computer. If this screen appears again follow these steps"
Check to make sure any new hardware or software is properly installed.
If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.
If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable compnents, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Next I tried to boot the machine from a Damn Small Linux cd. As it booted it stopped to give the following message:

There was more than this, but as I was copying it down, the text disappeared to display a black and white checked screen with a black X shaped mouse pointer, which could not be moved. At this point I powered off the machine.
Now the computer is even worse. On powering it up, it doesn't always display anything at all the the monitor (even the POST details) and does not appear to do anything. Other times, it will display the POST details and will begin to boot as normal, only to have the monitor turn black and stay that way, with the machine apparently not doing anything.
So anyone have any ideas what could be up? It seems to be certainly a hardware problem since both Windows and Linux seem affected. I have never used Damn Small Linux on this particular machine, so I don't know if it would normally boot without problems.
What do you suspect the problem would be? My first guess would be faulty memory (though it passes the memory check at POST). Any advice on what to do to try and fix this machine? I have not added or changed any hardware recently.
Any help with this matter would be greatly appreciated.
