Random reboots hard to troubleshoot

February 3, 2013 at 21:00:22
Specs: Windows XP, 4gb MB
I currently have the following setup:
Intel Core2Quad Q6600@2.40GHz
DFI Lanparty UT P35-T2R motherboard
4.0GB of G.Skill RAM
WD Raptor 10,000rpm hdd
PC Power and Cooling Silencer 750 EPS512 PSU
XFX GeForce 8800 GTS 512

For some reason I am getting random reboots and I cant find out whats bad. The HDD came from the last build I had and I just swapped it into this one and its been fine, but one day my computer just started randomly rebooting and I get no message. I turned off the "Automatic restart" in the control panel settings and it doesnt even give me a BSOD. I checked event viewer and got nothing. There is no trigger as well, although it seems to do it more when im playing Counter-Strike(i know its old). I dont think its a heat issue because I grabbed one of the garage fans and have it blowing right into the case and it doesnt seem to help. Sometimes it will reboot as soon as I get into the game and other times it will let me play a few rounds and then reboot. I did notice that if I run prime95 on the blended test or the large FFT test it reboots immediately, but if I run the small one I can run it with no errors. How can I troubleshoot this properly so I will know which component to replace? I already tried a new PSU and it had the same problem. Put one RAM stick in at a time, made sure and cleaned off all heatsinks, cpu and gpu are running at good temps, system is not overclocked...ran crystal disk on the hard drive and it said it was healthy, ran memtest for a couple hours with no problem, took out the sound card. My only guess right now is that its the motherboard, but how can I be absolutely certain?

Get AIDA64 and check CPU temperature (Computer > Sensor)
http://www.aida64.com/downloads
U can also run stability test (Tools > System Stability Test & leave only Stress CPU and FPU, un-tick the rest). Run the test ad click Statistics tab and monitor CPU temperature.

Did you check the CPU temp or just set up the "garage fan"? Check the reading in the BIOS. High 30s to low 40s at idle?

CPU temps are fine. When I check it its around 37°C and as soon as I start the Prime95 test it reboots.

If your internal temps are really in the good range (I like HWMonitor and SpeedFan) then you might want to try resetting your BIOS to defaults and the going back in and resetting your CPU, memory, hard drive/boot order, etc. to make sure that some more obscure setting has not become changed some how.
You can also try updating (or rolling back) your video driver to see if that is not causing it. It is possible that your driver has become corrupt or a new driver may have an error or compatibility issue. Likewise, you can try updating other drivers manually, especially if you have let Windows Update change any of your drivers recently. Use only the system or component manufacturer's site for drivers.

You have to be a little bit crazy to keep you from going insane.

I have had this problem for years unfortunately and when I decided to tackle it again, I updated the drivers for the motherboard and got the newest drivers for the vid card from nvidia. I reset the bios to defaults as well and nothing.

Run stability test & the same time monitor CPU temperature.

Disable automatic reboot on error.....

EDIT
"I turned off the "Automatic restart"
Ooops I missed that.

Always pop back and let us know the outcome - thanks

Sorry, missed it - have amended #8.

Can't add anything to what you've already done I'm afraid.

Always pop back and let us know the outcome - thanks
