Is my GTX 460 Faulty?

post #1 of 9
Thread Starter 
On certain shades of Grey, i get random flickering green pixels, if i take a print screen, they continue to flicker on that shade of grey in paint, and if i move the image around in paint, they follow it around.

But if i save and upload the image and send it to one of my friends to view, the green dots arent there. The print screen doesnt save the green dots, which makes me believe that it is either a majorish hardware fault, or a driver fault.

i really cant get a picture of this, but you're just going to have to go by what im saying

on the insides of the horseshoe shapes on this image, there is a random amount of flickering green pixels that appear


i really have no idea what to do, and i want to try and solve this issue before it gets any worse

It seems to me it can be a hardware failure, probably the GPU. White random pixels usually means memory, flickering textures/colors/jaggies = GPU. Try to ramp up the fan speed to 100% and see if it still does it; if not then the GPU is overheating and that would be the sole reason of the artifacts. If at max cooling it still does this then the card might be faulty. But before you begin, do a complete reinstall of the graphics drivers, you never know how a corrupted driver may act.

Hmm it could be the monitor itself. A lot of monitors use dithering to display colors outside of their bit range, meaning they make the pixels flash back and forth, rapidly, between two different colors to generate the illusion of a 3rd color. It could be that your monitor is at fault and failing to dither properly for that shade of grey.

Can you test it with any other pc, or try another monitor with your rig?

Being that it's only with grey, I see this being a lot more probable than it usually is.

However, first step is always to reinstall the drivers, I'd say re-install the drivers for your monitor as well.

its not my monitor, as it doesnt happen if i use the integrated graphics on my motherboard at the same resolution.

I will reinstall the drivers now to see if it still happens.

Also, my graphics card cant be overheating, It is idling now at 32 degrees, and i haven't seen it get above 55 degrees whilst gaming, (it reached 53 whilst playing crysis 2, which i would assume that those kind of temperatures are normal)

And my card is running at stock clocks (what the card came clocked at) so its at 715mhz for the core clock, and 1600mhz for the ram.

underclock the gpu and see if the problem persists

even when put back to stock clocks of 675mhz, the problem still persists

Hi patawic. How did you get on with the clean installation of your drivers? You could also try testing the card in a second rig to see if the same issues appear.
