Windows 7: Random Reboots

I installed Windows 7 Ultimate (over XP) on December 5th, and have since had frequent, spontaneous reboots several times a day. When I check the event viewer after each reboot, it contains dozens of errors that I cannot make any sense of. I cannot find a c:\windows\minidump file, but I am attaching a copy of the errors I have had today from the event viewer. Please help!

It seems like a lot of the errors in eventvwr are related to the hard shutdown. Have you gotten a true BSOD? you can simply search on *.DMP for the file of it isnt in minidump. On 64 bit systems it is usually found in c:\windows and called memory.dmp

No, I haven't gotten a BSOD. My PC has either been rebooting or freezing. Just searched for *.dmp and got no matches.

This is just a guess. An upgrade from XP to 7 is not an accepted path. You said you installed windows 7 over XP. You did not do an upgrade did you?

I upgraded from XP to Windows 7 and had to choose a "custom" install. The custom install did not preserve any of my programs, but it did create a folder named WINDOWS.OLD that contained all of the files that were in "My Documents." I had to reinstall all of my software, and I deleted the WINDOWS.OLD folder after moving the files it contained to an external hard drive.

Sounds like you did everything right.

Either it's overheating or your PSU is a problem or it could also be bad RAM, but i doubt .


Could be a virus. Run a virus scan.

But for now try this click on compuer icon, go to properties, advanced settings, startup settings. Uncheck the box for automatic restart. This should work, but there is a deeper problem.

I unchecked "automatic restart" days ago, and it still spontaneously reboots. Five times already today. AVG Internet Security found nothing. Spybot Search and Destroy found nothing.

I've opened the case and all fans are working. I also have a liquid cooling system.

Unplugged the cable from the power supply to the DVD drive and tested it with a multimeter. Readings were normal (12V and 5V).

If it were me, I would try a repair install (use Windows 7 DVD and do an upgrade)
If that did not work. I would just reinstall.

Reinstalled Windows 7 as an upgrade as you suggested. Only one reboot since then, although I haven't used the computer much over the past couple days.

I downloaded HWMonitor and attached a screenshot of the results. Not sure how to interpret the readings but I'm guessing that the line for +12V should have readings close to 12? Does it look like my power supply is bad?
