my screen turns pixaltaed whenever I play games.

[zenkei]

I think it's overheating because it's incredibly hot when I touch it but I've opened the case and put a fan right next to it and still freezes and goes all pixaly. It also says that the driver has stopped working then recovered when I alt tabbed so, I tried different GPU drivers and updated to the latest version and that still didn't work. Help would be greatly appreciated

Here's a picture of what the screen looks like when it's pixalated

here are my specs ask me if you need more info:

Only thing I can think of left is either the PSU or card turning bad.

I have a 900 watt PSU that's decent right how would it be having trouble?

is it normal for a card to be like this after 2 years like even when I turn shadow warrior to low graphical settings it happens sometimes.

 

[zenkei]

Its most probably a burnt nvidia chip.

can that be fixed or is it better just to replace the graphics card?

 

[zenkei]

Did you ever changed the thermal paste? It may have leaked into places it should not. If yes, then thoroughly clean the graphics card with isopropyle alcohol and apply a small quantity of thermal paste in the center of the chip making sure it won't go outside of the chip.

I did a massive clean of the graphics card a month ago, because this problem was started then and I only started talking about it here. I opened it and saw no leakage only dust. So excuse my inexperience but would the thermal paste be visible at if it was leaking?

 

[zenkei]

Only in case of extreme leaking you can see it, otherwise a thorough cleaning is the only solution. Small thermal paste build up can be as much noticeable as water in a sky blue container.

well there's no leakage from what I've seen. But for these past few days with the weather cooling done in Aus, I've been able to run games like shadow warrior capably in medium level graphics, but not ultra like the game defaults my graphics card too cause it should be able to handle it. So I'll probably get thermal paste for the chip as well but, what are some solutions to cool down the comp quite well. On hot days opening up the computer and putting a fan next to it seems to have done nothing what else could I do besides water cooling cause I don't think that'd do much to be honest.
