Please Help! Windows Vista logon problem

[ucrdem]

10. Hmm. Here's what I'd try next:

Shut down normally, unplug or power off, wait 30 seconds, power on and boot up normally. Then repeat (shut down normally, etc.) 2 or 3 times, and see if Windows repairs itself, which is something it happens to be good at.

If that doesn't do it, and you can download and install apps, I'd try either installing Microsoft Security Essentials, from the MS website, and/or Spybot Search and Destroy, free home edition, link here: http://www.safer-networking.org/spybot2-own-mirror-3/

Let them update before scanning, then do a full scan. MSE will be quicker than Spybot which can take awhile. Follow the prompts to fix any issues, shut down, cross your fingers, and more than likely your PC will start up again normally if it hasn't already. If it doesn't, you might have to go to plan B, a repair-reinstall using the DVD. But let's hope not. Good luck!
