HELP NVIDIA 6800 GT GRAPHICS CARD

HELLO,,
I have a 6800 GT card installed.. recently it as started flashing little pixels all over the screen. then when i start a game up to play, it all goes funny screen then resets..
Any ideas what is wrong with it..
Many thanks

 

maybe the fan might not be working properly. The artifact you see on your screen are because the video card is overheating.

When you play a game, the video card is getting hotter because games are real hard on video cards. That is mostly why the game is crashing. the card over heats and the whole system crashes.

Open your pc and turn it on.
make sure your fan is working properly and it runs smoothly.

 

Thanks
Checked the fan its working. changed the power lead, that seams to have stopped the artifacts but when try to load a game it wont work.
Tried a performance test software it does the easy and medium 3d grafix but wont do the hard grafix.
Still baffled..
please help doin my nut in
thanks again

 

make sure you have the latest firmware of every thing and then check the cards temperature

 

I have the latest graphics drivers from nvidia and the card running around 70..
Still resetting when i try to play games or benchmark test.
Last nite tried the card in my mates pc runs fine plays ganes no errors..
So wot can it be.
Many thanks for ya time

 

what are your specs and what are your friend's?

 

does the card need extra power?

 

yes it does.

its a 6 pin i think

 

which drivers are you using
i'm using 77.77's on mine
but there may be a lot better ones
now... that driver was stable on initial
install way back when GT's were the card
to get... hope that helps my 2 pennies
