Improper restart

I honestly can't tie these two together, but I never had this problem until SP1 was downloaded. I entered into the situation where I needed to restart the computer and it won't do it. It appears to but right before the multicolored balls begin their dance there is a blinking cursor up in the upper left hand quadrant of the screen. This is as far as it goes. The keyboard is dead as ctrl/alt/delete doesn't work. I checked the Microsoft tech area but can't find anything helpful.

Boot into System Recovery Options to run Startup Repair a few times.

Use the DVD or Repair CD: System Repair Disc - Create

Startup Repair should automate System Restore, but try it also from the Options list anyway.

Well, I'm almost embarrassed to tell you, but maybe it will help someone else. One of mt usb hubs went south. I just unplugged everything but the mouse. Then I unplugged the mouse and connected it to that hub and it wouldn't restart. Again, thanks for your help. I'll try to troubleshoot more before I cry wolf.
