OK, put everything together, everything worked fine, installed everything, blah blah. I realized that my NIC was ISA, and my Epox 8K7A doesnt have ISA slots, so like an IDIOT I yanked the NIC out the computer while it was still running. The computer spontaneously shut down, and now won't even turn on when I hit the switch. I checked all the connections, I don't think anything came loose (especially checked the power switch; it is definitely still connected). What should I do? I have a spare PSU, should I try that? Or is there some breaker that I can flip or something. What could possibly cause the computer to shut down so spontaneously? (YES, it is still plugged in). PLEASE HELP
