Since you restored and it worked until you rebooted, maybe there is spyware. Have you run your antispyware and antivirus programs? Run them in safe mode by pressing F8 once per second on reboot. You may even have to disable system restore by right clicking on my computer/properties/system restore-check turn off system restore, then run your anti stuff and after reboot turn system restore back on.
Only a suggestion,
I have been having a major problem with my desktop view when I turn my computer on or restart it - its blown up to quadruple the size and no toolbar at the bottom. I have tried several things to fix it. I uninstalled the adapter driver and restarted the computer and it reinstalled it and then i updated the driver. that didn't work. I reset the screen resolution many times and every time i restart it - it goes right back to the blow up desktop screen view........I also went back and restored the computer to a date 2 weeks prior and it was great for a little while (like a day or so) then when I restarted the computer we were back to where we were. i have never had this happen before and i have not clue what to do. Any ideas?
