My PC has started crashing whilst playing full screen apps (mainly demanding games) The screen freezes turns sort of checkered with distorted colours, I have no choice but to reboot. Its getting stupid now, keeps happening after about 3 mins of playing.
I have virus scanned and found nothing, tried system restore and again no change, i thought it might be due to my harddrive being almost full (partition 1 = 105 gig cap 24.7 gig free partition 2 = 127 cap 10.9 free) but that was from deleting a vast amount of unused programs and still no change.
I have also update to the latest graphics card drives still no change.
I'm out of ideas really, i don't think it's my hardware because it has been working fine for the past year or so but here is my rig anyway:

Windows xp prof
service pack 3
250 hdd
4 gig ram
inter core 2 duo @2.2
nvidia 8600 GT
p965 Neo mobo

just in case here is a hijack this log:

help would be very much appriciated because these random crashes are just becoming rediculous.

thanks!

Hello and welcome to the forum.

I have removed your video as it contains language that is inappropriate for our audience.

I think it would be interesting to see what your GPU temps are following a gaming session. Download and run this: GPU-Z Video card GPU Information Utility

oh ok =?

i will post back with results.

I think the problem is over heating as my graphics card does not have a fan, i think i need a new one anyway but for now i have a usb fan pointed at the card ^^
