Ive kicked my CPU unexpectedly and started to face these problems,When I start the computer,i get a small beep that lasts about 0.23-0.69 sec(really small in intensity,not so loud as the normal beeps) and the computer starts normally,after some time when i open a game(Witcher 2 or DOTA 2) (OR) connect a pen drive,monitor goes black with no signal and the same beep i mentioned earlier goes on infinitely,it never stops until i pull out the plug this happens no only in the above two cases but when i open 14-19 tabs in chrome, I've tried blowing compressed air and cleaning the card but both of em aren't working.Help appreciated..I almost forgot to tell that its a brand new one,i just bought it 3 days back
