I have an MSI AE2010 AIO computer with an Athlon X2 3250e that has an overheating problem. It would work about 1 minute, then start rebooting, each time get less into the startup cycle until it would just shut off.
If I do get into the BIOS at this point, it will usually show that the hard drive can not be found. I originally thought it might be a power supply issue, but replacing that made no difference.
The reason I think it is a heat problem, is that I took the computer into the garage where the temperature was 0C (yay Canada) and the computer ran fine (although I froze my fingers), and ran PCMark 7 to completion.
The custom heatsink is pressure fitted to the CPU (no thermal paste) and GPU (I think) and sends the heat via two copper pipes to a small fan.
I've added thermal paste (arctic silver) to the heatsink, and the computer will now run for several minutes before shutting off.
I've kept the back off the computer, and placed a house fan blowing directly on the CPU. This allows the computer to keep running, as long as I don't overload the computer. As a load test I ran PCMark, and the computer hangs on test 2, but I can still operate the computer (play Spider Solitaire) at this time.
Speedfan shows that the computer shuts down when the CPU temperature reaches over 30C which seems very cool to me. I played a youtube video with the house fan turned off, and the temperature climbed to 40C before it shut off, but computer was unresponsive before that (although the video kept playing).
Given that this problem developed over time, and the CPU temperature at shutdown seems low to me, is it possible that the computer has overheated in the past, and now is more sensitive to heat?
Would the next repair step be to replace the CPU or to replace the heatsink ($70 from MSI)?
Or is there another component that is heat sensitive that I am not aware of?
Also, if there are more (better) diagnostic tips out there, would be much appreciated as well!
