I'm having a problem that halts the boot up process of my system when it hits the Windows Welcome screen. What happens is I get a Warning box with no message in it..just the options to click yes or no. This will also happen if I add another user and the box appears as soon as I click on the user to logon. If I click no the systems boots up...and if I click yes the system boots up but seems slower than usual. I have ran anti-virus, anti-spy software and I have checked the event viewer...but there are no errors. Any suggestions? Thanks!
