Hey, I realize that you get plenty of threads like this and that my description will probably be relatively unhelpful, but this is the best I know how to describe the issue.
I have an Nvidia GeForce 7900 GTOC. Lately it's been acting really twitchy; When I play games it'll randomly start rendering models incorrectly, jutting parts off of them, flashing random things, and just not working correctly.
The problem started a few months ago when I was using Star Trek Legacy; models started not appearing correct, like they were on strings or not in completed stages.
After this, it began happening in many different games, games that I have played successfully many times. FPS games like Quake IV or Prey are extremely difficult to get to run correctly; I keep having to restart the game to get it to work and then it will only stay correct for a while.
There are basically two different types of errors.
Consistent model/texture errors, where a model has a string jutting off of it.
and flashing model/texture, where models and textures flash across the screen with random white flashes. Flashes last for less than a second, but flash constantly.
I have all of my Nvidia drivers up to date, I have the latest DirectX, I've tried reinstalling the games and such, all that jazz.
Currently I'm running with ---- AMD Athlon 64 X2 Dual-Core LIVE! +4400 2048MB memory 320GB HD ----
I have no idea what this issue could be. Any help would be greatly appreciated.
I didn't make it!
You want to check your graphic card drivers and that you have the lastest versions directx . If problems persist , id recomment contacting nvidia
I really can't make heads or tails of your photos (the lines in the first could just as well be part of the game, for all I know), however based on your descriptions it sounds like you're getting texture corruption. It's a sort of artefacting, and in my experience tends to be suggestive of a memory problem. Possibly overheating, possibly going bad. Possibly just overclocked too much.
Check that, first. Stick a fan over it, if you have to. See if it helps.
I would also say the card is either over-heating or dying. Can you tell us its temperatures? You can use this program.
Take a look inside as well and see if the gfx card fan is choked with dust etc.
Take the card from OC to default frequency and see how is doing
Well I used the everest program and the temp fluctuates from 140-165 F. I've been told this is within the recommended temps is it not? So I would guess it's not overheating.
As for the overclock, I don't even know how to mess with that.
