Hmm. Ok. That's not from Device Manager.

Go to Start - Run, then type in msconfig and press enter
Click on the Startup tab
Look for any entries that might be driver related and uncheck them. You can always recheck them if necessary.

Otherwise, check Control Panel - Add/Remove Programs and see which drivers are listed. Then you can try uninstalling a driver, and then rebooting to see if it pops up again. Do them ONE at a time, so you can pinpoint which driver is the problem.
