"one of these solutions have helped. And I did not want to buy a new graphics card. So I came up with the solution (after a long search) that you need to put the CPU Core voltage of 1.25 V . And since it works wonderfully.
I have a i7 4770K CPU and a NvidiaGeForce GTX 680."

and i was going to try it.

ive already done memtest, it said nothing was found.

Nope none of these are working.
I launch assetto corsa for 3 minutes i start to hear buzzing strange sounds and fuzziness from my monitor.
then my pc freezes and i have to press my case power reset button.
and log back on > even viewer: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
