Garry's Mod VERY WEIRD crash.

[Alexybob]

Hi all,

I am having a very strange problem and I can't find any answers anywhere. At seemingly random times, the game will crash, and my screens look like this:

I have no clue what could possibly cause it, its not overheating on the part of my gpu, but it could be my RAM.

Specs:
Win7 64 Bit
Nforce 780i
4GB DDR2 RAM
Intel Q6600 2.4 O/Cd to 3.0Ghz
GeForce GTX260
1000W Power Supply

Any and all help would be appreciated.
Thanks,
Alex

Edit: This problem is exclusive to Gmod, forgot to point that out.

Thank you all for the help. I mean really? Not even a response?

It looks like your video card is dying to me. RMA it.
