Computer Keeps Restarting

PC keeps restarting by itself, no error screen just restarts. No new hardware has been installed.

I cant attach the perfmon html file since the program times out when creating the report

The BSOD Dump is attached


Is Windows 7 . . .
- x64
- the original installed OS on the system
- OEM

- hardware 3.5 years old
- OS installed 3.5 years ago

Possible reasons

How often does it happen? Is there any problem with the power supply? Are you using a battery backup that has installed software? Have you created a scheduled task? Do you get any kind of warning, like a popup window or a countdown?

It happens random from every 5min to 20min

No problem that I know of with the power supply

No battery backup

No scheduled tasks setup

No warning at all, and when restarted It does not say windows recovered from an error so this leads me to beleive its the PSU but I thought I would post the log here to see if someone can find something else causing it

Well now I am not sure its the psu since I left it sit with nothing running for 4 hours and its still on without restarting
