This should not be happening during the install of SP2. It is either a 3rd party program or more offten a device driver that is doing this. The best action would to be to remove any additional devices by unpluging them from the computer (eg. Scanners, printers, any device not needed to boot and have a network connection). Also make sure that all virus scanners, or extra little applications that are running in the notification area (aka system tray/the little icons near the time). You can usually disable these by right-clicking them and selecting exit.
Let me know if this helps or not.
