well i tried reboot my friedn pc and it work, but the display stteings are mess up. they only let me go to the lowest quality and i cant run any software. is there a way to fix this? please help me out.
You can also try updating the video card drivers. If it's an OEM computer, check the manufacturer's website for updates. If it's a custom built PC, then check the website for the motherboard for updates (if it's using built-in video) or check the manufacturer's website for updates of the video card (ATI, Nvidia, etc...).
