I have a Pent4 2.667 GHz dekstop that is having problems while booting up. The video card check runs fine but when it gets to the BIOS startup, it starts having problems. It displays the BIOS information and the processor info but then it stops. It doesn't run any memory tests. I thought it might be the RAM so I bought a new stick and the same thing happens. I actually got it to boot up fine but that was after a dozen or so power cycles. Once I was finished with that session and restarted the PC, it returned to freezing before the memory tests. Any ideas? I'm afraid it's the mobo that's the problem.
