Hardware failure, but what?

[kyleetrotter]

So my family's PC was randomly shutting down and I determined it was because the cpu was overheating because the heatsink was too dirty. We cleaned it and all was fine. I decided to reformat it and install a newer OS on it, and when I was auto updating the display driver, it turned off. I thought maybe it was still overheating, so I opened it up and saw that the heatsink was pulsing on and off and I knew it was dying.

So I ordered a new heatsink and now when I try to turn it on, everything boots up perfectly but I get no display from the monitor, not even the POST from the BIOS. Do you think it could be a fried cpu or a mobo problem?

Any ideas?

Reseat your CPU

I doubt the CPU is fried. Make sure you have the heatsink mounted correctly and that the fan is working (on top of the CPU). You may want to take out your CMOS battery (if you dont know what that means, it looks like a large watch battery that is silver). Leave it out for a minute or two and re-seat it. I had issues before to where I could not get my workstation detected by my monitor cause of the changes I made, and this was the only way it was fixed.
