Windows Crash to fuzzy screen...graphics card dying?

Hi All...

I'll make this brief, I originally posted into the memory section thinking a new kit of DDR3 was causing my problem - but old and new kits both get the same problem occurring.

my original post is "nvidia driver crash with 4GB DDR3?" in the memory section, and goes into more detail, but i haven't made 15 posts and this thing won't let me include the link!!

My PC crashes to a screen of artefact-filled fuzz as per the attached pic, when I try to run videos, or load a game, or run my TV Tuner application. Not every time but enough that i feel i'm playing russian roulette every time i run one of those apps

I've tried the latest certified drivers for my GTX280, and tried older ones to see if the new drivers were the issue. the problem occurred under Vista 32 and 64.

So now I'm starting to think it might be a hardware fault on the graphics card, and the other changes to my system were just coincidental...

any opinions valued!

Well, the CPU normally idles at 36 - 40 degrees C, i have a Noctua C12 cooler on it. I ran a 13 hour OCCT stress test on it with it OC'd to 3.2GHz (from 2.66GHz ) and it was stable. Current temp according to Everest is 38C

Graphics card is 55C as I've used Rivatuner to tweak the fan setting to 60% up from 40%

there's no way loading up a TV App is going to put that over the unsafe temperature mark!

The graphics card-to-monitor cable.

Normally it's either DVI, VGA or HDMI.

DVI and it's secure. Not sure how that being loose would cause a problem for video accelerated stuff when normal windows operation is fine though?

It wouldn't Did you buy the card new or used? Has the outer case of the 280 ever been removed?

I think you've cooked either the GPU or the RAM on the graphics card. I used to have a 7600GT in my HTPC which worked fine to begin with, until after a couple of months graphical glitches started to appear, and the system was very unstable. It turned out that the fan was spinning slower than it was reporting, and although I rectified the problem, the damage to the card had already been done.
