Thanks for the reply. I have heard others having the same problem. My HP Pavilion laptop (Dv6485) also has a bad motherboard, and I know of another friend of mine who had one go out. I just want to be sure it's the MB because I can sell the CPU and don't want to sell someone a dead processor. I suspected a bad CPU because there was no beeps, even with the RAM out, which usually causes a beep code, and a sure sign of a bad processor is the absence of any beeps.
