Go to Control Panel>Performance ,Maintenance>System> Advanced tab > Startup & Recovery.
select the Write an Event to the System Log , and Uncheck the Automatic restart.
Video card drivers and video settings in Bios often interfer with games ,but it will help if you get some error messages .Make note of them and then post back.
Also check that your firewall and/or antivirus is not conflicting.

What kind of video card do you have again?
Try opening the PC by taking the side panel off and play for awhile that way. If this "fixes" the games it just means you have a heat problem and need to add more fans to your case.
Good luck!
