Computer Just restarting itself D: (Help meh)

[Koolguyv2]

I havnt been on the website for forever...My main account got deleted or something,anyways

Whenever i play Counter strike source or any game i guess..The computer after a little bit will just restart itself,had the computer for 2years..Had never had aproblem...And its only on games..

I got a Dual core and a nice nivida Graph card or w/e they are called :P

But ill be playing for maybe 30minutes on Css and it will just freeze for a sec then restart,This is a custom built desktop and with Vista 32bit operations system..

And it also does it on minecraft now..But it takes about 1-2hours to restart playing minecraft,iget no errors or anything..It just retarts.

Could aswell be a small mistake within the custom built PC, perhaps short circuit / overheat.
The method you can find below should do the trick; reboot your PC after having changed the settings.

Start button -> Control Panel -> System and Maintenance -> System -> Advanced system settings (left side, Task Panel) -> Startup and Recovery -> Settings and then uncheck "Automatically restart" (under System Failure).

Ravallo beat me to it, but as far as I understood that isn't going to fix it. Just instead of a reboot, your computer will switch to an error screen and give you some debugging information (which will be useful in solving the actual problem).

Coretemp + Rivatuner = awesome method for keeping check on them temps. Once you've got that run Prime95 and Furmark to see if it's your CPU or GPU that's causing the crashes.
