Hi All,

I've done hours of research on this issue, and I am coming up empty. I would REALLY appreciate any help. The computer restarts randomly, even while in the BIOS. This occurs every 5-10 minutes. I'm really at a loss here!

1) Verified that RAM voltage and timing was correct.
2) Verified that CPU and GPU were within normal operating temps (see HWMonitor report attached)
3) Swapped out sticks of RAM. Only ran with 1 stick at a time.

The only 'strange' setting being returned from the HWMonitor report that I can tell is the "Temperature 1" (bold in the report) which is likely a faulty sensor, as I have seen many many threads with reports of extremely high temps for this component however it is not actually that hot. For a similiar issue see thread: http://www.tomshardware.com/forum/274657-31-computer-re...

Check the simple stuff first. Do you have a faulty power strip into which the computer and peripherals are plugged into?

My friend had this strange random re-boot issue, and the case was a faulty power strip.

Sorry, I should add one more detail. Ran Memtest86, it passed. I will have my friend verify the power strip when she gets home tonight.

Also one other 'strange' note, thought it could just be Windows thinking there is a problem, it removed her Firefox automatically after the very first reboot and gave the following error... She is on Windows 7 Ultimate x64. I would have thought it might be a software issue if the computer didn't restart while in the BIOS.

The program or feature "\??\C:\Program Fires (x86)\Mozilla Firefox\firefox.exe cannot start or run due to incompatibility with 64-bit versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

Anyways, I will check on that tonight! Thanks.

First check all internal cables are well connected and pc inside must be neat and dust free with plenty of airflow and case fans. Then if its still happening youse hot cpu tester pro for 6 hours to test all your hardware. Then yul know if you have bad hardware. If all test come up ok then try different chipset drivers and videocard drivers and make sure windows is up to date. Also make sure you have a good power supply with plenty of watts to run your hardware smoothly . Good luck

Are you sure that your CPU cooler is installed correctly? If it isn't it could be restarting itself as a safety feature. As far as I know it should be turning off rather than restarting if that is the case, but it is still worth checking.

to me it sounds like either drivers, or a psu having trouble putting out the proper power consistently

So just an update:
1) Power source isn't the issue. Tried different areas/plugging it into the wall.
2) The computer IS actually shutting down, not restarting like I originally thought (sucks working out the issue on the phone.)

This leads me to believe the issue is a thermal shutdown, I turned on the motherboards "Restart after power failure" option and it still did a complete shutdown with no restart. So either the motherboard is detecting something wrong with the voltage coming from the PSU OR it thinks something is overheating and shutting down.
3) We ruled out the video card by removing it and using the onboard card.
4) CPU is reporting temps in the low 40s Celsius during usage, nothing crazy. Heatsink appears to be flush with the processor and is on tightly, the fan wire is connected tightly and reporting RPMs.
5) All power cables/fan cables are secure.
6) I don't think it is a driver issue because the reboot can occur while in the BIOS. I realize there can be incompatibilities with a motherboard/BIOS and hardware, however the system was working for 1 month before the issue randomly cropped up last night. No updates have occurred in the last 2 weeks.

Unfortunately I don't have a PSU lying around to test my theory first, so... If any of you have any other thoughts I wouldn't mind them, but what would you all suggest I go about RMAing first?

something else i would try, is doing a fresh install of windows if you haven't.if it is actually shutting down, there are virii that do that

Sorry to reply to an old thread, but I was looking at high temps on TMPIN1 .... I have the same board. Just wanted to say that I doubt your crashes were because of temperature. I had similar problems with DDR3 1600 memory. It would pass memtest .... My suggestion would be to set your GSkill as 1333Mhz ... it is what I did and all was stable after that. There are many posts on the net about AM3 chipset and DDR3 1600 ... if you really want to run the 1600 some additional tweaks are needed in Bios, but the end results are negligable... just run 1333Mhz is my suggestion.
