Strange problem, when my PC's upright and I turn it on, an alarm goes off and nothing loads, no splash screen, nothing. But when I put it on it's side, it loads ok.
The post code stops at 9.0, at first I thought this might have been a chip problem, but if the chip was screwed then putting the pc upright shouldn't make any difference.
I've put a new battery in just incase that was dead, the cpu fan block seems to be on tight, it just seems very strange that it works on it side which suggests there's something loose and not making contact when upright, but I can't see what else I can do apart from leaving it on it's side.
