Why the computer restarts during games?

When I'm just working on the computer, well, sitting there reading something, writing code, surfing the Internet etc, the computer does not restart and everything works fine. But when I start to play gta san andereas(or other games), he after some time restarts. Play gta in 20 min or less or more, then restart. I went to the event viewer and there kriticheskaya error kernel-power(System rebooted, completing the work correctly. Possible causes of the error: the system stopped responding, experienced a critical failure or suddenly power is off.). This I used to not have played gta as much as I wanted, and with the computer everything was fine. Have you searched the web for this error, found something that supposedly problems with the power supply, vidyuhi percent, with the disc. With BP all the rules, with the percent too, none too, hard so-so. The old drive is already 40791 hours worked. Since the state of alarm, writes crystal disk info. Before such nebylo, and so for a week.

Temperature hardware clearly surpasses.
Check it BP.

Maybe from hard. It has to be tested. But the Software just won't fight hard, so he's most likely on the verge.
