Recently i had purchased new pc With Follow details:
Processor: Intel I7 2600K
Ram: 4GB DDR3x2
Graphic: ATI Radeon HD 6850
But from the day of purchase i started facing the problem: "Display Driver stopped responding and has recovered"
so i format the pc, then again same error,i had updated driver and updated bios and tried a lot of things but nothing helped, so finally i complained to seller and got replace my graphic card and now everything is fine, So every one else having the problem, try replacing the card.
