if you have a standard monitor plug it in and on the lower right will be a gpu control panel. set the video output to 640 by 480 the lowest for pc. if you dont have a monitor if you see the pc (hp splash screen) hit f8 go into windows safe mode and then change the video res and reboot if there nothing on screen at power of the computer check your tv settings.
