Taking a look at another person's computer for them, that's being selective when it decides to start up. It's an older P3 800. Once it's on everything is fine, but most of the time when I turn it on I get no signal while everything else powers up. I've tried taking out all pci cards, swapping the video card and power supply, and reformatting the hard drive. I'm about to start swapping the RAM out, but I was just wondering if anyone has an idea what could be causing this problem. I have to let it rest awhile too before it decides to power back up. Thanks.
