Why freeze my monitor when I play games?

[LeoIeiri]

I dont know reasons but around 20 - 30 minutes sometimes my screen freeze,another times distorcion color and glitches

I buy a Nvidia GT 710 2GB ram and I have this problem only play games with old nvidia geforce 210 1GB not this

I have updated all drivers and for precaution I put again nvidia geforce 210 and I format windows 8.1

I wanna play battlefield 3 with GT 710 with nivida 210 fps and screen is very low

Freezes are usually due to either the card not having enough power, or due to overheating. Distortion and glitches (artificts) are usually due to memory corruption or the card failing to output textures or shaders correctly (sometimes due to overheating).
