I recently bought and installed an ASUS p5vdc-mx with an Intel Pentium 4 Dual Core 2.6 GHz processor. The installation was fine, and it ran for about a week. Now I will turn it on, it will start running like normal, there will be a click, the humming noise will lower in pitch (I think this is the hard drives spinning down as the fans don't seem to be changing speed), and the screen will lock at whatever it's doing. It will then click again, the humming will rise in pitch to where it was before, but the computer will remail locked. The power supply is giving me all I need (I have removed a hard drive and the graphics card and the problem is still there), the hard drives seem to be fine (don't know why that matters but hey), and the motherboard power light doesn't go out. I am guessing this is either a bad mobo or a bad processor. Any guesses which?
