Sadly, when the computer doesn't turn on, there are no beeps -- it's as if there is no motherboard, just the fans turn on. The box is pretty clean -- certainlly no mouse pee and not much dust. Its not overheating because this happens when its been off for a day. I haven't touched the seating of the memory, but alas I have only one chip, so I can't easily check the ram. But it seems unlikely since I could compile my kernel (many times) without any problems.... but what could explain inconsistent module loading errors?
