Random Reboots w/ Homebuilt Computer

Specs: Windows 7, Intel I7 860/4 GB
Hello,

I've finally decided it's time to put this issue to rest and I don't mind changing out parts as necessary. Back in January of 2010, I bought parts to put my computer together which I will list below. Ever since then I randomly had reboots occur, but they wouldn't be often enough for me to address the issue, I always just figured it was not getting enough air circulation in the chassis. More recently it's been rebooting more regularly (a few times in one evening and sometimes wouldn't finish booting up). I've never seen the BSOD, only would I see it completely power down for about 5 seconds then autmatically spin up and reboot itself without an issue.

I've also recently been interested in doing some overclocking and would like to get rid of this issue if possible. I don't believe it is my CPU temps as I've done some preliminary checks of the temps recently and they don't seem to be going much higher that 40 degrees Celsius and idles around 30 degrees Celsius. Below is a list of all the equipment I've used to build my system. I started with a different video card than what I listed below. Thus, I don't believe that's the issue since I've had it this issue the whole time. Also, I haven't found any viruses that has caused this. Again, I've had this over the past couple of years happen while my computer would be running, but some evenings it would run better than others and I was starting to believe it was temperature related, but I'm doubting that theory. Any suggestions of what it may be would be helpful. I'm pretty savy with this stuff, but haven't tried troubleshooting it too extensively yet.

Thank you very much ahead of time!

Does it reboot while in the BIOS?

Not that i recall. I have only had issues when ive changed settings for overclocking and it would start rebooting and just hang. Ill try to play around in bios a bit tonight and see if i have problems. Any other areas that i should check? I have a suspicion its memory related. I just got another 4gb of the same memory. Ill swap it out and see if the problem tracks. Thanks so far for the help.

You're welcome. If it doesn't reboot in the BIOS then it sounds like a software problem and not a hardware problem. What if you apply the overclocking settings and stay in the BIOS. Does it reboot then?

The 1st thing you need to do is disable the auto-restart feature, that will allow the BSOD to be displayed.

And if you haven't already done so, test your RAM with memtest86+.

Check the voltage ratings on your memory and if needed, set them manually.
Run Memtest.
Update your drivers from component mfg's websites.
If you have not seen this yet, it is an pretty comprehensive overclock guide for your CPU.

Alright, so I've disables the auto-restart feature in Windows 7 and I've also started running Memtest for the night and day today. I'll see what happens when I come back. Unfortunately it will take a day or 2 of testing to really see if the problem goes away. I also set the BIOS back to defaults in case there was something I've done in the past that could be factoring into why it's not running right.

@ Fingers - You mentioned something about an overclocking guide, did you mean to put a link in the post to it?

Thank you all for the help so far. I'm going to keep trying things and keep updating this thread as I learn more. This will probably be an ongoing investigation for a week or two.

Check back above, I added it where it should have been.
Either I forgot to add it or it did not take for some reason.
