So decided to boost my computer and changed my old GTX260 the a new GTX560ti 448 core. After the card change my computer is running perfectly on desktop, while watching film and internet browsing. But when i start a game, after only 1-3 minutes of play the screen freezes with some white marks all over it and windows closes the game. This has happened i BF3, 3d mark and minecraft.
To solve the problem i tried:
- Reinstalling drivers
- Checking if i have a heat problem
- Changing powersupply (from Corsair HX520W to Cooler Master GX650W)
The only thing that have worked is to underclock my brand new card from core 732 mhz to 675 mhs. Now i complete 3d mark test and play BF3.
Is this a normal thing having to do? Can it be caused by the rest of my computer parts (old)?
