Strange Happenings When Gaming

[Le GoogelGuRu]

When I playing some old basic games like, for example, the game GeneRally... the computer suddenly restarts, like you hear the shutting down noise and then it starts up and loads Windows again from the beginning.

It happens on the exact same parts of each game listed below:

GeneRally - When I start racing.
Midtown Madness - When I click Exit To Windows

I have no clue what could be causing this, what are your thoughts?

Either a glitch/virus or your PSU isn't strong enough. What are the amps on the 12v?

I doubt it would be a PSU problem, but it's probably a software conflict. What exactly, I have no idea, but check to see if there is a patch available; or try to run the games in Compatibility Mode.

I tried the running-the-games-in-compatibility-mode and it still happens... Any other suggestions?

I doubt it, but could it be heat?
I am thinking its a conflict error. Try to enable the BSOD, i cant remeber how though, but someone here does
