I get a BSOD while playing games

[Snakebites1]

Hi there
I have been experiencing BSOD's for over a month now and they only occur when I play games and it is beginning to frustrate me so I would really appreciate it if someone could help me out

I only have 2 minidumps available as I recently tried re-installing the OS but the other BSOD's had the same error : UNEXPECTED_KERNEL_MODE_TRAP , STOP 0x0000007F

Thankyou

Have you tried updating your video card drivers?

Yes my video card drivers are up to date

ATI Radeon HD 5700 Series Graphics Card
ES 550W PSU
Gigabyte GA - MA74GM - S2 motherboard

Try removing the video drivers completely and re-installing them... The minidumps show that the ATI driver is at fault
