Green pixelation on my m806tu before a crash

Hi, I am getting some issues with my m860tu. When I am gaming primarily, after 15 minutes of playing, I am starting to get green artifacts on the screen and then it seems as though the system locks up. (I have noted this with Day of Defeat: Source at first and now tonight with Team Fortress 2)

This also appears to happen when I start the system after such a crash and I boot into windows 7 welcome screen.

Right now, I am using windows 7 safe mode with networking and there doesn't seem to be any issues right now. My drivers are the latest ones from nvidia 195.62 I believe. Or if not, I'm downloading them right now.

Could the issue be with my graphics card, which is a 9800m GT? And if so, I purchased my system from a now defunct company in August of 2008. Where could I possibly get service for my machine now?

 

Does this only happen with gaming? Have you checked your temperatures?

 

Right now it only happens after I game for 15 or so minutes, other than that, it doesn't happen.

I am updating my drivers and will monitor my temps and get back to you.

 

Your video is becoming unstable at high temperatures, pointing towards dying GDDR or a fault in the soldering of the card which can be solved by baking.

But most likely is the GDDR.

 

Is there a tutorial for doing this (baking)?

Update: I have uninstalled the nvidia drivers and I am running windows 7 at the basic resolution and there seems to be no issue with the green pixelation. You may be right with the temperatures.

 

Yes, there is one around here. Use the search option.

 

If you ruled out drivers, it's probably a bad GPU. Here's a tutorial on baking.

That looks very scary and I'm going see if the problem persists before I try doing something like that.

Has anyone actually done that in this forum and had success with it?

 

If you read the thread, a number of users have done so successfully.
I know at least some CLevo owners have done so as well.

 

How long will baking keep my card functioning though? Is this a process that I will have to continuously repeat?

 

Assuming baking works, most people will get a few more months out of a card before they maybe have to try again. The thing is, though, baking is largely a stopgap solution; it works because the solder on the board is inherently bad and develops cracks over time as the card heats and cools, so baking just reflows the solder to fill in those cracks.

If, on the other hand, the problem is bad GDDR, then you'll just have to get an entirely new card.
