Why does my PC freezes during gameplay?

[diversion1001]

I cant solve this problem, and i have been trying for a while.When i play games like samp (San andreas multiplayer), Call of duty (all versions), or league of legends my PC just freezes when i get into a big war, fight or a lot of smoke and dirt just freezes everything, even the keyboard and mouse and sound.Then i must restart my PC and all over again.

Processor : AMD Athlon(tm) X4 750K Quad Core Processor 3.40 GHz
GPU : NVIDIA GeForce GT 640
RAM : 4 GB

Please i need a solution !!

Your gpu is weak for those games. The best improvement you can make is a new video card.

1. Download HD tune pro and run a full scan of your hard drive to check for bad sectors or errors.

2. Make sure you have the latest Nvidia Graphics installed.

^ He has a GT 640 - look at the benchmarks - not a good gaming gpu.

BTW - What is your monitor resolution?

Its true he has a weak gaming card.

But keyboard and mouse shouldn't freeze right? You should be able to press Ctrl Alt Del to get back into the windows menu.

No Graphics Card should hang up the system entirely. Hang up the game, maybe.

The resolution question is a good one though, but Gt 640 is weak for almost every resolution.

weak gpus won't cause game freeze...yes you will get low fps but not a freeze...

I have had black screens & freezing caused by video cards - in my case the temps were getting high as the card worked hard.

Install MSI afterburner and monitor your gpu for load & temps.

I installed MSI afterburner and it didnt fix the whole problem, but i can play much, much longer now. Thank you !

With Afterburner I the fan profile, set my fans to come on sooner & faster so that when I game my gpu stays as cool as possible. Great free program.
