So I had a old ATI 5770 video card lying around and thought I would change out my moms ATI 4830 for that one. So I unplugged the 4830 and put in the 5770 and then plugged into the onboard video and restarted windows. Well nothing happened and my monitor never loaded so I tried the video card and still nothing. I tried everything and the monitor never loads. The old video card DVI VGA HDMI resetting CMOS even different HDD's and nothing. I cant even press Ctrl+Alt+Del and make the computer restart. Any help would really be appreciated since it isn't even my computer and now it doesn't work.
