Almost all games on laptop are pixelated?

So, almost all of my games are pixelated and it's been like that for some time. I don't think the temperature, checked on HWMonitor, and the only games that are not pixelated are The Sims 2&3 and Minecraft.
I have an Acer Aspire 5755G
Windows 7 Ultimate,64-bit(Service Pack 1)
DirectX runtime version: 11.0
Processor Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz 2.20 GHz
Installed Memory(RAM): 8,00 GB (7,85 usable)
Graphics Card Information:
GeForce GT 540M
Driver Version:285.90

And I had owned it for like 2 years or so. And a long time ago I kind of dropped it on the ground…
But after I dropped it, the games still worked and after a long time they became pixelated.
And I wanted to take a screensho, but I can't for some reason.

Sounds like you need to get a new one. Or send it on repair.

There are 2 possibilities. You physically damage the video card OR you need to update your video card drivers to the newest version from the nvidia website.

It's your video card, it does not support some games, like ig game uses OpenGL4.0 etc.
and your vido card supports OpenGL3.6 that might be a problem. Becouse other games still works, and try
change resolutions up, maybe help? You can find resolutions of games in options -- > video
