Computer sometimes runs perfect for days if not shut down.

Most other times I get numerous types of blue screens or other crashes usually after about 10-15 minutes of running. I have had times when after a crash I could not get the computer to run windows repair or get through the start procedure without crashing.
My computer is 4 years old running windows 7 with an i7 processor and a Radeon XD 5670 Video card. It just seems so random that it will start properly and then run perfectly if not shut down. I have reseated my video card and I can not see any loose connections. I know the obvious answer is to leave it running but we are subject to a lot of power disruptions here at this time of year.

If the problem is not obvious, all you can do at this point is troubleshoot the cause through process of elimination.

Have you checked the Windows system monitor to see what the logs/alerts might say about the crash?

My first guess would be a heat issue. Second guess a driver/software issue.

Have you checked out your cpu temps? Is the cpu heatsink seated properly? Was the cpu heatsink installed with the proper thermal paste? Does the case have good airflow?

Are all the chipset drivers up to date? Are all the component drivers up to date?

It doesn't seem to matter what program I am running, sometimes I start the computer and do nothing other than the virus checker running and come back and find it has restarted with the message that there was an unexpected shut down.

Thank you For your responses Chunkymonster. I have found the error messages that were captured seem to point to several different possibilities. I have tried to address the ones I could, updated all drivers, cleaned the computer, and checked the seating on cards and memory chips. The CPU has not been tampered with other than my blowing the dust out after the problems showed up. The computer has run perfectly for the past 2 days because I have not shut it down at all. I believe that I will take it in for repairs the next time it fails as it seems such an intermittent problem that I need someone to test the power supply and perhaps perform other tests that are above my capabilities.
Thank you.
