I recently bought a new laptop (Toshiba Satellite) that runs Windows Vista Home Premium. I haven't had any issues, until I installed a series of Windows Updates on 8/16/2007. Now my computer restarts automatically everytime I choose "shutdown" from the start menu. The only way I can successfully turn it off is by manually holding the power button on the computer until it turns off.
I've tried doing a system restore to before the problem started, but it hasn't helped.
I'd appreciate any suggestions for a fix! Thanks.
