Heyo, this problem has been ongoing for my computer for quite a while now and only now have I decided to fix it. Whenever I run certain games like Bioshock Infinite, Rising Storm, Arma 3 Beta, and XCOM: Enemy Unknown my screen turns black and shuts off while my computer is still running. I realize this means that my graphics card is over heating and in order to not fry itself it has to turn off the source, but I was wondering if there was a way to fix it without using a lot of money. I have tried cleaning it and the power supply with the fans are working fine. All help is appreciated, thanks.
Computer Specs:
OS: Windows 7 Ultimate 64-bit
CPU: AMD Phenom(tm) 9650 Quad-Core Processor (4 CPUs), ~2.3GHz
Memory: 6144MB RAM
GPU: Card name: NVIDIA GeForce 9800 GT
If you need any other information just tell me, thanks.
