dodgy graphics card..green spots??

[dave g]

i have a new pc which i built the other month,the graphics card is a gigabyte gtx460 756mb card.

today i noticed some green speckles on the screen,they are there even in safe mode so im assuming its the card thats faulty and not the drivers??

i just put my monitor on the motherboards inbuilt graphics to test it and no speckles..i took a screen grab of the screen with speckles but they dont show up in the picture so had to use my camera.

first pic is with my camera and gtx 460,2nd pic is screen grab with gtx460..no dots.
with inbuilt mobo graphics i get no dots.

Are the spots there when you turn on the computer from cold?

If it happens after a while it could be that the card is over heating, try it with the side of the PC.

Does the power supply you are using have enough umph for all the components?

I run a 3 monitor system and was getting the exact same problem with just one of my screens. I tried another graphics card but it was still doing it. Turns out it was a monitor failing.

i have already tried the monitor on the inboard graphics as in first post..

When i plugged my monitor into the on-board card, it worked fine. Have you tried different resolution settings, also are you using Nvidia monitor control or similar package?
