My graphics card stopped responding all of a sudden when i was using my web browser, crashed with a white screen. Then when i restarted the machine, it didn't start, hung on to a black screen. i tried resetting the pc and it started up but this time with 2 red lines on the screen. The screen appeared like there's no driver installed with the minimum resolution in place. then when i tried to update the driver via device manager, it went to black screen. and now it doesnt start.
