Computer Randomly Shuts down

Hey guys, I'll get right down to the problem and what I've done.

My computer just started to randomly shut itself off. I've gone through completely reseated all hardware, replaced the power supply, tried known good working memory, even brought the computer to a different location with good known electricity. I haven't added any new hardware to my computer. When the computer shuts itself off, I have to press the power button and a BIOS message appears saying that the computer was shut down due to a Thermal Overheating problem.

With that being said, I removed the heat sink and fan off my processor, used isoprophyl rubbing alcohol and removed the old grease and put on new thermal grease. Artic Silver. I replaced the heat sink and fan (a nice zalman full copper fan) and the problem still occurs. This computer does run off a nice belkin surge protector normally. Oh and when I go into the BIOS after it shuts itself off, the processor heat is at about 50 celcieus

Any other ideas?

Thanks,
brandon

You can usually set the temp at which the CPU shuts itself off. Maybe that number was set too low for some reason? Look on google for your CPU plus max temps. What ever comes up as the max temp, change it to that in the BIOS

GOod point. And now that I think about that, I was searching for the temperature threshold in my BIOS settings. I was not able to find it. I will look online to see if they have that option.

Maybe one of you guys might know?
I have a Intel PERL850 MOBO

Thanks,
Brandon
