Advice Needed - 6800 GT Overheating Problems

Hey all,

I'm having some trouble with my computer, getting random artifacts on the screen usually in the form of green and purple pixels during periods of heavier load (whilst scrolling websites fast or viewing pictures, especially during gaming when the artifacts are all over the place and the screen hangs every few seconds).


artifacts on pictures

All signs I can see point to my graphics card being on the fritz and overheating. It's an XFX Nvidia 6800 GT which has never been overclocked and is currently running at about 56 Idle and 70 ish during gaming, which although slightly high isn't at dangerous levels.

Most of the time it's producing a perfect picture and I was wondering if firstly you think I'm right and that it is a problem due to heat and secondly could I salvage the card by applying some Artic Silver and replacing the stock heatsink or is it a scrap and replace job?

I've tried using rivatuner to turn the cards fans all the way up and even underclocked the card to get the temperature down but it isnt having much effect.

My Computer Specs are as follows:

AMD 64 3400+ p
1GB Single Stick Kingston RAM#
ASUS K8V - SE Motherboard
XFX Nvidia 6800 GT
500W PSU

Any advice would be great, cheers for your help guys.
 
cheers for the quick response ku-suma,

i did try updating to the latest nvidia 84.21 drivers on there at the moment, i'll go and find some beta ones and see if they help but i think its probably hardware related.
 
Steps to take:

  1. Clean out the inside of your computer, removing dust
  2. Tidy all the cables up allowing more airflow from the fans
  3. Apply AS5 to the 6800GT
  4. If the temps still arnt reduced, then i would advise investing in a Arctic Cooling NV cooler.
 
cheers guys,

i did give my case a quick clean and made sure it was cable clear, but that didnt seem to drop the temperatures much. Thing is, the temps that the card is showing really shouldnt be high enough to screw up the picture like that, 75 degrees ish should still be fine.

anyway i'll give it another go and go see what xfx have to say about it all.
 
try underclocking it a bit, maybe XFX screwed up and undervolted it a bit on accident. that would cause it to give artifacts. RMA it.
