Put this in the BSoD forum, although there's a BSoD it seems it would be more appropriate here.
Basically, I have a problem with my desktop computer (a Phillips Freevents PC). It came with Windows Vista already installed, and when I had previously had problems with that, I obtained a Windows 7 installation disk from a friend which worked temporarily and in the meantime I bought a Windows XP SP3 installation/repair disk and continued to use that. However, the computer began to reboot at random intervals and now just won't turn on at all. I have tried reinstalling the system time and time again to no avail. I currently have no system whatsoever on my computer.
The only change I can think of is when I installed Windows XP, many of the devices were missing and I used Device Doctor to install them again. However, now I can't get onto the system more than a few seconds at a time.
My computer is completely wiped at the minute and have no idea what to do.
Any help would be appreciated!
