PC Locks up only when playing Certain Multiplayer Games

[epicmidget]

Hi. I have been having this problem for ages which my PC will Lock up after playing about 10 minutes in multiplayer games and require me having to manually turn off the PC and turn it back on. I have tried loads of fixes such as driver updates, cleaning of my PC etc. but nothing worked. What happens is the PC will instantly lock and the screen will freeze, there is also a loop of audio but only a loop of about 0.5 of a second of audio so its just a loud noise really. Singleplayer, i can play games for hours on end, no problems. Can you help me? Thanks. :confused:

Some of the Games i have noticed crashing are:

Battlefield 3

Tom Clancy's Ghost Recon Future Soldier

Assassins Creed: Brotherhood

Specs:

Intel core i5 650 @ 3.2 GHz

Nvidia GTX 570 1.28Gb

8gb RAM

Windows 7 64bit

Hanns-G HS233 120Hz Monitor
