OCuk value GTX260 problems, help needed!

Hi all,

Almost two months ago I purchased from OCuk one of the OCuk value nvidia 216 core 55 nm GTX260s. This turned out to be manufactured by Sparkle and worked very well. About half a week ago whilst playing Fallout 3 or DOW2 the screen would do a variety of bizarre things after about 30 seconds. The screen either freezes, with an occasional flicker and the games sound sometimes continuing, not letting me leave the game and requires me to restart the machine on the front. Other less common problems are the screen turning gray or the resolution dropping and parts of the screen appearing in different coloured rectangles. Sometimes after the physical restart the bios screen will be garbled resulting in it being totally unreadable. I tried running furmark to see if it was a graphics problem and the stability test will complete but stange gray images are displayed every few seconds.

I'm guessing this is some form of over heating problem so I have tried to monitor the heat on the run up to the problem using rivatuner. The last temp this records is 50 C before the freeze occurs which seems fine. I have checked to see if the cooler is loose and can't see any obvious signs of it. I have ran the gtx260 in two machines both displaying the same fault.

Any ideas?? I've got the feeling my card may be going back to Sparkle.

Thanks in advance,

Paul
 
Oh, I forgot to mention the card works fine when not in game and the second machine I used it on had a clean install of Windows XP with all the latest nvidia drivers.

2nd machine spec with clean install of Win XP:
Q6700 @ stock
EVGA 750i ***
4GB OCZ reaper ddr2
550W Hiper PSU
Creative Audigy 2 ZS platinum pro
 
Checked for dust build on heatsink at all, if not it could be the cause of some overheating. That 50c could be from the lock up point or their after, whats the consistant temp say 5 mins before?

No need to remove cover.

Look inside the area where the fans housed, any dust will build up across the heat sink fins. Compressed air blasted at the heatsinks exit point does the trick nicely, or just blowing hard :)
