Hi all, Ive had this graphics card for 1-2 years now, and it was working fine - i could finally play titles like COD4 MW1 and MW2 on my pc when previously I couldnt. However, within the last 6 months or so (and i havent done anything about it) after about 5-8 mins of gameplay my computer will give me a black screen and restart automatically, or sometimes the ATI catalyst control centre enables VPU recover to get me back to the desktop. I opened my rig up after it overheated once, and it was really hot - the fan on the GPU seems to be spinning though. It was probably the hottest thing in the case, the heatsink on my Q6700 CPU was virtually cold. I cleansed the card of any dust, but didnt attempt to check any thermal paste there may be between the fan and the card. What I dont understand is why it started up all of a sudden? Is it a case of: A) Format and fresh install of everything, and using the latest drivers - i havent updated them for a while, but didnt think they would make a difference? B) Having a look at the thermal paste on the GPU? C) Suspecting the PSU, even though it was fine previously.. its a Levicom 450W PSU, bought years and years ago, and the minimum recommended spec is 450W i believe HELP!
