this sounds like an overly aggressive registry cleaning and you may have to do a a restore repair.

i have just done a full recovery (fresh install of windows)on this notebook and installed SP1 and nothing else except the latest drivers for the printer. have been fixing pc,s for 8 years and don't know what is the issue here, is it a dodgey usb controller or bad CPU requests ?????? HELP

It turned out to be a usb cable that did not have good enough sheilding.

tried a new cable and it works every time.
