My computer suddenly stops reacting when i using it.
I remember the first time it happened i was playing GTA:sa,the screen stopped suddenly and no more reations.I don't think the virus cause it because i haven't have any online service when the first time it happens,also it happened just after i bought my computer few days later and i tried to re-install the window but it still happens.
Signs of stopping reacting:
It begin "program busy" suddenly but the mouse can be moved like this
Then,it become no more reactions and the mouse can't be moved anymore,at the same time, some black bars appear and some place of the screen was twisted like this
It always happens ,sometimes when i open a folder ,sometimes when i playing a song with the media player,sometine when i doing nothing, and the black bars remain the same place but the twisted part will change positsion,
what's wrong with my computer,please HELP ME
