My PC freezes completely – the picture freezes, the screen gets garbled with lines and the sound gets stuck and a continuous humming sound comes out, when I play high graphic requirement games like Crysis and Bioshock 2. Once it happens, nothing works! No pressing of window key, no ctrl alt delete, nothing. I simply have to keep the power switch pressed, it shuts down and then I restart. The PC runs ok on restart, I can play games. Low graphic games don’t give any problem. High graphic games again give problem after time varying from 10 mins to 30 mins. Again if I force shut down and restart, the PC works like normal except in high end graphic games.
I was told power might be a problem but I have checked power requirement on some websites (put in your PC’s config and the site tells you the size of SMPS needed). I have more than 100 W more power than needed.
I spent like Rs. 100,000 (US $ 2500) on this PC just so I can play high graphic games at high setting smoothly. It feels like a complete waste of money and I might as well have bought something at one third the price.
I have tried scouring websites, tweaking BIOS settings, tweaking CCC etc etc. Nothing seems to work.
Can anyone here help ?
My PC configuration: Intel core i7 920, Gigabyte EX58UD5 mobo, 4 GB DDR3, 500 GB Hard drive, Radeon 4850 x 2, 1 GB graphic card, 650 W SMPS, Cooler Master CM620 cabinet, Windows 7 Home premium 64 bit and other stuff.
