You have made a common error in as much as you have not reloaded your Video drivers. It is always prudent when refomatting and reloading to write down the name of the drivers for Sound, Video and Modem. If you have the driver discs all well and good, if not you will need to download them from the Net. You may have to remove the cards and look on them to ascertain the correct name for the drivers in order to look for them on the net. If the Sound, Video and modem are integrated on the motherboard, you should find all the drivers on the motherboard disc. Good Luck..........Dave
