PC crashing computer whilst playing games

[Mr Arky]

My nephews PC has a tendency to crash whilst playing games, and i'm sure the more graphically intense the game is, the more it was crash, yet it does it to simple 2d games.

Whilst playing, the monitor will say its going to sleep, followed by a black screen.
Then the windows start up recovery will appear, asking whether to start in safe mode or run normally saying it has recovered from a crash.

Strangely the actual computer seems to stay powered throughout the whole thing, with its lights and power still on.

It only does it when he is playing games.

Its just a simple pc, with a gt 240 and an amd processor.

It has ran fine in the past with games but have never seen it crash before like this.

Any suggestions?

Thanks

Could you list the full specs.

Also under administrative tools, check the error log, to see if its the driver crashing or losing power.

Thanks
