Hey guys, I have made a thread about this before but it was pretty dead and my problem hadn't occured for a while since so i thought it was okay. But, i was wrong, and up until recently i have been putting up with this annoying problem. The Image: The Problem: RANDOMLY, occuring anytime between 1-2 weeks, every 1 or 2 days or once a month, just randomly, i will get artifacts in-game. Little artifcats like little squares and black gaps in-game. This is when i know the problem occurs. So i leave the game before it crashes and the artifacts get worse. I then go to ATi Tool and scan for artifacts, the image above is what i get. If i leave it scanning for longer than 10 seconds or so it freezes my system and i have to hard reboot. .... The thing is, upon that hard reboot, my computer runs fine and a 'scan for artifacts' finds nothing and the card runs okay. OR, i could simply wait 10 minutes and run 'scan for artifacts' again without rebooting and the artifacts will be gone and i can carry on playing again. It is totally random. What i've tried: Well, i've never overclocked this card or fiddled with it like that in anyway for a start. I have adjusted the fan speeds with ATi Tool, it runs at like 100% on full load but never gets hotter than 60-70*C. I've cleaned out the card multiple times in the months i've been having this problem, it has an odd heat sync which likes to attract a lot of dust which i found ABSOLUTELY CAKED in dust the other day, im talking 1CM thick. So i cleaned that out and card ran 10*C cooler. re-fitted the card onto the motherboard. The Whine: Meh, admittedly i haven't done much since it works 80% of the time which leaves me even more cluelous as to what the problem may be. I have ordered this (Along with a nice new system recommended by Bruins, excluding the GFX card) in a vein attempt to perhaps fix the card as it may be the heat but the temps i run at aren't dangerous at all and shouldn't be giving me artifacts? Help Me: Pleeeeease? Thanks a lot my friends! SPECS: Operating System: Windows XP Pro - Service Pack 2 Motherboard: Nforce 4 Gigabyte GA-K8NS Ultra SKT 939 6.70 nForce drivers.
