So I just bought a PC and installed windows ,drivers,etc...it turned off by itself on a weird way .. mouse started blinking,keyboard turned off,screen went black,PC shut down but the power button was blinking and then I pressed it and it turned on and went right back to windows ..where I left off ..what the hell happened ?

It's the power-saving configuration that makes it act like this. Your computer may be configured to "sleep" and also shuts down the hard drive quickly when you are away from your PC. You may go to Control Panel -> Hardware and Sound -> Power Options to adjust one of the Preferred plans your PC is using. I'd particular prevent the hard drive to hibernate or sleep or turn off too quickly by giving it a large number.
