Fred,
How long does it run before it shuts down? And does the computer actually turn off or go into hibernation mode? If it takes about the same amount of time every time it would almost sound as if you have either a heating problem or an option that is doing it. Is this a new computer or something that has just started? Have you tried booting up in safe mode to see if it happens there? If not do so, and run all of your virus scans and spy ware programs while in safe mode. Also do you have System Restore with a restore point before this started? I have never had much luck with using System Restore but occasionally it will work. But if you have it and the problem continues, before going into safe mode, disable it and do a defrag. Then run your virus and spy ware scans and see if you can find anything. System Restore will store some parts of viruses and the only way to get rid of them is to flush it out. How long does it stay off before it starts back up? Also when you reloaded it, do you have the old type 2 or 3 disk set-up where you format the hard drive with one, load the system with another, and then the drivers and apps. with the other disk, or are you reloading from a partition on the hard drive?
