15 minutes scan on BiT

9582 operations, 21118 errors

Nvidia Ge Force 7600 GT about 2 years old started showing recently.

Seeing weird texture drops in some games and on a black screen few "green looking" pixels.

Will post more info later, any advice until then?

This is a known issue with some systems.
See these old posts for details

In summary you can ignore a few of these errors. If you get a lot of them, then you should be more concerned.

I know I've read all of these topics but I got 21k of them thats why I am posting. Thats twice as much as operations scan performed.

I do see them, at the XP startup loading screen about 4-5 whitish/greenish pixel dots randomly placed.

Around 3-4 of those on most of the dark background.

My nVidia reads around 55°C GPU temperature in control panel. I've been hearing some weird sounds sounds lately but I thought it was my hard drive maulfunctioning. Could overheating be the reason for those?

I would swap out the video card and see if that fixes the problem. Sounds like the video RAM is bad.

I will take the card out and clean the agp contants and vent tommorow (which is I assume more than crowded with dust)

If that doesn't help I will need a step by step guide with the voltage checking thingy that some people said it helped them (I know nothing about that)

Worth mentioning everything else but that card is approx. 8 years old, so is motherboard, CPU and power supply. It's an very old IBM computer that came as a whole.. with the very small case aswell (not much place for fresh air surge)

How is 55°C by the way?

EDIT: Overheating, I left computer chill for most of the night (due to very busy schedule I had to keep it active most of the time) and BurnInTest scan shows a very small amount of error (I didn't let it run for 15 mins but I assume it would be less than 30 at this rate) while old PC doctor PASSED the test.
