It's been running Windows 7 x86 and Ubuntu 10.04 x86 lately. So here's what it's been doing: Will boot and run just fine and dandy, totally stable through days of Memtest, Prime95 torture testing, playing video games, etc. Then, if I turn off the system or hibernate it, many times it will refuse to boot. A lot of times, I have been able to revive it by removing the power plugs and data cables from all devices and removing the graphics card. The other day, however, I mistakenly put the computer into hibernate mode instead of sleep mode from Windows 7. Any attempts to revive it have failed. I have used multiple variations of the PSU and video card from my current computer, as well as the old A64 3000+ CPU. It refused to boot. Game over, man, it's game over! (For the motherboard, I think). Anyone have any ideas?
