I recently formatted my hard drive and was in the process of setting up my burner, wireless, and web cam when I got a message saying that they cannot be set up because I needed SP2 or higher. I went to microsoft/windows and did the download and install. After restarted my PC I can only get 4 bit color and screen resolution can't be set any higher than 600x800. I did a virus scan and avg found nothing. Any suggestions?
