recently upgraded from a x800gto2 to an EVGA 8800gts 640, but have been having real issues with Blue screens and strange game crashes. can play games for a while before they have weird texture crashes, but carry on running. have completely removed old drivers and using the forceware 162.18 drivers. anyone else having these problems or know of any solution.
You sure you removed the old drivers? I don't mean just catalyst control center, I mean the display driver too. Second, could you please post your power supply just for reference? Not trying to insult your intelligence here, just want to be sure. Lastly, it could actually be the GPU if those other things are fine. Is there any way you can go test it in a friend's computer or something?
If you are running vista; the drivers are the issue. The newer realeases of vista drivers have been so bad for me that I went back to xp. Go download the 158.45 driver (works perfectly) if you are on vista. If on xp, gl because the new xp drivers rock.
I have been runing a BFG 8800GTS 640 OC for about 2 months in vista 32 and haven't had one driver issue. I can't remember what driver I was running, but just updated to the newest one a couple of days ago and haven't had a problem yet.
From the symptoms, it sounds like a heat issue to me. Have you tried running with the side off you're case?
Aha! So I'm not the only one who has an issue with an 8800 GTS 640! Mine also came from EVGA. In my case, the card seems to be ok, but the 8800 doesn't like to play nice with AMD K7 and K8 chips. Its described in the release notes that come with the drivers. If I try to use Ntune, for instance, my computer locks solid, requiring a restart. And yes, trying the 162.18 driver didn't help at all. It disgusts me becuase the 7800 GTX that formerly occupied the computer didn't cause any problems at all.
As to your problem, it could be the Nvidia drivers or the psu doesn't have enough power. If its old, it may technically have enough power in wts, but has aged sufficiently to not deliver all that it claims. Other than that, a Seasonic 600wt should be fine, powerwise. I'd test the card in another computer, as has already been suggested. if it works there, then the card is probably good. If it s till causes trouble, then arrange for a RMA.
i have that card as well and none of these issues. I am running the .45 drivers and they are fine in vista. Secondly make sure that the vid card is alone on one of the 12v rails and all other 12v components on the other, that cards sucks the juice.
i am running XP PRO. just tried out 163.16 but to no avail. temperatures are all fine in ati tool and Everest, i have an antec P180 with plenty of fans, and all round after market heat sinks, etc, etc.
shall be building another PC for a friend soon so will try it out in a new system.
thanks for the help... maybe ill just have to rebuild...
