So this started happenimg from yesterday when i was playing gta v.My screen got frozen suddenly and i was getting green patches on the screen and pc would restart.Now i did a full os reinstall but now the graphics drivers are not getting installed ,the pc is gettimg forced restart at 4 % of driver install.The pc is booting perfectly without the driver even with the gpu intact.I tried installing in safe mode but when i restarted the pc,again got green stripes and the display wont come up.I have gtx 760 direct cu II oc.I have tried installing old drivers but same.
