jus today i started noticing a vista hang after the bootup..it stays on the black screen for about a min before the logon screen, before this it was like 2 seconds...
If it has only happened today i would not worry, It is more than likly an update like stated in the previous post. If it continues to happen re-post. Just out of interest are you getting alot of activity on your router if you have one?(This will indicate updates and other traffic)
sorry guys..forgot to let u know..problems solved..it happens as always..when i schedule a chkdsk..it never works and freezes ur next boot up...jus had to reboot with normal config
