...! The lights come on and all the fans work, but the BIOS isn't beeping and nothing comes up on the monitor... I've tried changing the motherboard, processor and graphics card... I have 2 RAM chips, and I've tried alternating between the two and the odds of both chips going at once are incredibly remote (But I'm buying another chip tomorrow just in case, I could do with more RAM anyway) I can't honestly think of what else it could be. We've tried disconnecting the HDDs and all other drives except the floppy, and nothing makes any difference. Is it possible that I caught a virus before that wiped the BIOS, remained on my HDD so when I bought a new motherboard it loaded up again and wiped the BIOS again? Please help! Thanks in advance...
