System boots up fine, when I run any programs the system reboots on me. I am still trying to use windows update. I am going thru computer withdraws.

Could be any number of things, but the most common cause of system reboots is drivers.

Have a look here: https://www.techspot.com/vb/topic44306.html

And try to elimate each step. One of them is likely your problem.

Good luck!

I did forget to mention this is a new setup.

I did finally get the latest bios loaded onto the computer.
The radeon 9800 pro card is installed ,but not the drivers. I can not keep the system up long enough to download the latest driver. It does semm to run the best in the morning. It took me 4 days to install 44 windows updates.
When I boot everything seems to be normal, temps are fine. 90 sec of going on line, it reboots.

something definately with the drivers, maybe a damaged usb port? maybe it shorted out the mobo or something.

I couldn't take it anymore, I started over with reformatting hd.

Everything semmed to be fine until I installed windows service pack 2. After installation, I rebooted. Every program I ran the system would reboot. The system would stayup long enough to check for patch updates. I remove SP2, everything is fine again.
