Any advice for a computer geek?

Well I was upgrading my processor in my HP A6400f and I did the research to find one that is compatible with the stock motherboard. Well what happens is that I turn on the computer now and it goes for 2 mins. and then shuts down for no reason. I did alot of troubleshooting, I mean alot. I am a motherboard freak so I know what I am doing most of the time. I have a couple of things that might be wrong, either power supply (unlikely), overheating (doubt it but is still a possibility), Bios (already updated it, so it's unlikely), or incompatible (in which I proved wrong here:http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01324212&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3686671\My specs are here (besides the fact I have a quad core processor):http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01390590&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&lang=en&product=3686671I am frustrated

Overheating is more likely. After the computer shuts for no reason, if you turn it on again does it goes for another 2 minutes or it turns off earlier?

Sounds like a classic case of overheating. Did you apply new thermal paste and upgrade the heatsink/fan?

overheating for sure. Download speedfan and see what the temperature looks like, if you get enough time before it shuts off

+1 on carefully applying the thermal goo. lots of people feel foolproofed/safe because they certainly have the correct gigantic mega-heat sink of doom and it is locked in tight... but without the gel you're only transferring a fraction of the heat away from the cpu and into the heatsink
