Have you run anti-virus/spyware/adware scans? If you ran these and found/fixed problems before the restore, then the problem may have been restored as well. If this is the case, then you may need to run the scans and fix the problem again and then delete the restore points.
Hope this is helpful.
When I boot up my computer it won't load any programs until it makes the Windows XP loading sound.(The sound that plays when you log into Windows XP) After it plays the notice everything runs fine, but it takes a few mintues before it will play the sound and load and sometimes it will freeze and lock up randomly and I have to restart my computer manuel by pushing the power button. And also my computer won't recognize my external DVD Burner, but all my other USB cords work. Thank you in advance for your feedback and help.
