Hello, my new PC is having a lot of problems with playing video files, I have tried with different players giving the same results.
It freezes and gives distroted color lines across the screen with a beeeeeeeep sound. It plays games at max settings without a problem, always with playing video files. (I have tried different files too).


I ran memtest, which ran for30 minutes no problem, cpu temp is around 40 and 1.4v. Reset the bios too, installed the latetst drivers for 5770. It also freezes everytime on prime95 on stock settings. I am using an old hard drive, but I did a format and reinstall through the windows cd. Using windows 7 64 bit 7600. Could it be the version of this windows causing this problem??
I was using this with my old system and had no problems....Any suggestions would be greatly appreciated!
