I have read your post five or six times, and it still isn't really clear! What exactly did you replace the heatsink on to cause these errors? Your first mention is of a video card, and the correct drivers should fix this. Your main post concerns usb drivers, so how is the video card connected with this?
It would help if we knew your computer type and model number, unless it is a self/white box build, and then it would be helpful to know the motherboard manufacturer and model no. All this will be helpful in troubleshooting the problem!
