Hi all,

I got Sager NP 9150 notbook with following specs:

- i7 3610

- 8GB DDR3

- 256GB Samsung 830 + 500GB HDD

- Intel HD

- Mobility Radeon HD 7970, Catalyst Mobility 13.9

- Windows 7 Professional x64 SP1

 

The problem is that I experience artifacts i games. But it's very random. I tested Crysis 2 and World of Tanks, in Crysis 2 I saw yellow shadows (but only once or twice), but I exerience corruption in WoT much more often.

Videos for illustration:

This happens also randomly - I can have a session when I see no artifacts, but sometimes I just fireup the notebook, run the game and I see glitches like in the videos from startup.

 

What is wrong with it?

The only time I experienced what is being described here was when my graphics chip and my CPU were overheating. A laptop cooler took care of the CPU and manually increasing fan speed solved the graphics issue. The higher the in-game settings, the more heat.

But on my computer it happens only in one game and it does not matter if the graphic chip is hot or not - I can doble-click the game and see stuff like that on the videos from very beginning, sometime after an hour and sometimes I can play and all is OK.

I figured out that the corruption happens in 95% when I Alt+Tab the game and then return to it.

 

Tried also Tomb Raider, so far no issues.
