Please let us know what new drivers were required. What were they called, what were they for & where did you donwload them from? If Windows update, do they show up in a fresh scan (choose the Custom button to scan for all possible updates)? Do they appear in Add or Remove Programs as installed?
There may be an entry in the Startup folder that's causing this. Start > All Programs > Startup. See anything there that may be the cause?
Also check in msconfig. Start > All Programs > Run. Type msconfig in the box & click OK. In the SCU applet that opens, click on the Startup tab. Do you see anything there that may be the cause? G
