Couple of days back my son decided to check his computer(XP Home) by running Chkdsk. Now whenever he fires up his computer he gets message 'press a key before 'x' seconds to stop Chkdsk from running.' He is not aware of choosing the program to run on every start up and would like to stop it from doing so. Is there some way he can stop this? We assume it's somehow connected to the 'startup' menu, but don't know which one to untick.
