Dunno if anyone can help or identify the problem, but ever since I updated the nvidia drivers on my Asus G53 laptop it's been getting bad artifacts. I was seeing it in the aero elements of Windows and I can't even run Unreal Tournament 3 because it glitches out and freezes. It was behaving itself just fine before the update. I had a solid 60 FPS in UT3 and now I can't even get past the first menu. I went back to the older drivers that worked before, but it's still acting up. Tried OC scanner and it can't even properly render the EVGA logo. I figured it was overheating, but the GPU temp is only in the 60s. During tests or when trying to run a game the screen gets artifacts all over it and/or crashes the driver or freezes. 

 I managed to get this error about OpenGL:

I am outputting through HDMI to a display, even using the laptop screen it still can't run any games. Well, I did get games to run for a while without artifacts by down-clocking, but the FPS was halved. Then I went back to default clocks and it was still halved. I checked power management to see if it was throttling something, but it was still on high performance. I have tried a clean install of the old drivers, but it's still being stupid. I'm lucky to get it working and even when I do it's only half the speed it was before. I don't get how something functioning perfectly fine can be irrevocably broken by a newer driver to the point where even the old driver doesn't work. All I can do with this now is browse the internet and if I'm lucky the GPU won't throw a fit.
