Gpu issue

Setup:
Laptop
Win7 64
i7 740qm
Gtx 460m
6gb ram
Drivers were updated to something.97 I can't remember exactly. Really recent like a month.

The problem:
Play a game/work/surf. After enough hours of my Laptop running without restarts, literally minimum of 10 hours a day, game textures would appear broken/stretched/torn/3d errors.

Restarting does *not* fix this but shutting down and reopening it right away does.

I've tried driver reinstalls (clean).

I've tried system tune ups and moar updates.

Nothing has improved.

My gpu does not overheat nor is it OCed.

This started about a month ago I think. Possibly a little further back. This actually triggered the driver update for me. Would have been using a 3 month old driver otherwise.


Is my gtx 460m up for replacement?


Different problem on my ati 5850m but same laptop hardware:
Video does not show on laptop monitor. It does sometimes but I get a broken display. I confirm the LCD isn't broke because my gtx 460 work just fine except for the broken textures in 3d. Putting the display output on hdmi works perfectly fine though. No errors and stuff.

 

I have come across a similar issue before where the Nvidia card will down clock into power saving mode, my GTX590 does it. Usually it will happen after gaming for a long period then pausing the game on the main menu,upon resuming the game FPS is extremely low and the video can seem garbled, only solution I've found is to restart the computer, restarting the game alone doesn't work. So you could try to disable all power saving modes in Nvidia control panel and in windows.

You could try running a battery of stress tests back to back such as 3dmark, heaven benchmark to try and recreate the problem in a shorter time while monitoring temperatures

If your computer isn't overheating it could be a voltage or memory problem and the video data is being constantly corrupted until it becomes evident on screen.

Run this OCCT kombustor with error checking enabled, see of you can get it to error out.

When it happens check how much free memory you have and what processes are using your resources using task manager and resource monitor, whatever you find instead of restarting when it happens flush the memory cache.

I wouldn't necessarily consider having to reset the computer every 10 hours a problem, try and give you and your computer and break every couple of hours:-D

 

Noted.

I will do this when encounter the texture problems and run OCCT right there or tonight when I sleep

any ideas on the ati thing?



Thanks
