You can uninstall drivers through device manager. Right click Computer and select manage. Highlight device manager on the side. You'll be presented with multiple categories, each with items in them. You can try click on them to uninstall. If you are using the same Windows install that was orignally used with different hardware you you've changed the motherboard and processor, but left the hard drive, this is probably causing all the problems. Make sure all the old drivers get cleared out.
