I was rebuilding my computer bit by bit after my old one died on me. I recently purchased a motherboard/cpu and I used an old harddrive with windows xp on it and my old video card from my previous pc.
Everything worked fine, all usb ports were up and running, monitor worked great. Than I went to install Windows 7 on my computer from a usb thumbdrive.
Everything went smoothly until I got the the first restart. When the computer turned on again, all fans were turning, hard drive was spinning, and led lights turned on but my monitor went black saying no connection, and none of my usb ports work (no lights on my keyboard or mouse).
