Faulty card?

[1ofaKind]

Hi All,

A while back I had some hard locksup playing Cod 4. Tried latest drivers etc made no diff.

Now I'm playing WoW and have noticed a bit of weird graphically 'not tearing' but like big polygon's appearing and very occasional glitchiness.

Thing is I have numerous lockups now in game where I can't get back to desktop. Music still plays etc.

Updated to latest drivers today & also ran Nvidia diag for 1 hour and it failed and crashed the diag.

So anything else I should test before I email Bfg about what to do (Had that card about 18 months now - 8800GTX OC).

I got this with a 7900gt I had and it was power related but not the psu but *** capacitors on the card failing. Although recently I've swapped a family member 8800gts due to this, playing at max res on cod4 & he was getting purple & grey squares on *** screen. Initially a reboot would fix it but its become more & more apparent and its come down to the card memory so in your case it could be the cards memory dying slowly.

Sorry ti hijack this thread,but earlier this evening,i was playing COD4,when it crashed,and i got a no signal on my monitor.
Powered off my pc,then restarted,and fired up COD4 again,and it played flawlessly for two hours,untill i quit,any ideas if this is a GPU/PSU problem,first time anything like this has happened(had this machine for about 19 months),GPU is an Inno 640mb 8800gts,thanks.

If its doing that at stock, I would RMA it.

Remove the card from the PC and see if you can remove any dust build up. I ran my GTX overclocked all the time and twice in games would the screen black out. If the game didn't freeze then it would throttle and reduce my FPS to about 30% of the power to let the GPU cool. I then ran ATI Tool to stress the GPU whilst monitoring the GPU and core temperature and seen the card hitting 105'C which is the point of throttling. It seems as if the card was overheating so I took the card out, removed the little bit of dust build up and hey presto my overclock and games were perfect again.

It might be the problem, it might not be but it's worth a bash.

I downloaded ntune last night and put the temp monitoring on. Ran up WoW and was playing - alt-tabbed and the temp was 75 degs. I have put the latest drivers from nvidia's website on 175.19?

I will take the card out tonight and check. I haven't overclocked it - but it's factory overclocked to 636 or something like that.

I dunno if that nvidia stability test is bugged but it always crashes out after a couple of minutes.

Doesn't sound like overheating then but I'd give it check over anyway. Maybe try underclocking the card after you put it back in and see if the problems still remain. The process of elimination can be frustrating so good luck .
