last night i was playing games and then my pc crashed with a striped screen. after then when ever i boot up my pc crashes after couple of minute. then i uninstalled the driver. Now if i plug in my gpu my pc becomes slow. it takes time to boot up as well. some time it shows no hard drive found error msg. and also if i try to install the driver again it will crash the whole pc. Any one knows whats the problem here? my gpu dead or there is some other problem.
