I was taking a nap and when I woke up the power supply was dead. I replaced the power supply and have it all hooked up, but I now can't get my computer to boot up. The light on the MOBO is on, and everything seems to be good. One thing I noticed is the CPU fan no longer goes on where it had been previously plugged in. However, if I plug it in elsewhere, the fan works. So, now the question seems to be, is the CPU bad or is something wrong with the MOBO? Does anyone have any thoughts as to how I can test either or any other thoughts on troubleshooting?
