Desktop PC troubles

Desktop PC was giving us troubles for like half a year. It seemed centered around graphics card (failed to POST, VGA card fail, crashes at runtime), but it did have some memory problems too (hard to reproduce; overnight gcc was ok, overnight memtester was not, with single-bit problems). Today Lenka worked with DVDs a bit, and result was crashes "a bit too often". That looked like a clue, so I tried disconnecting some hard drives. (This machine had 4 hdds + DVD RW)... and that helped. PC is now powered by two power supplies (400W + 300W), and I believe problem is solved. Next step is probably getting 2TB drive...

Morale of the story? Yes, power problems are easy to trigger in PCs, and no, power supply is not clever enough to shut down.
