Extremely slow boot windows 7 usually 8 -10 hours of waiting. To get to this point . has taken this computer 73 hours - from reboot because of hang up to restart. Then internet. Find page. Open. So far no one has answers or believes me, but to try sell me programs that don't work. I've run hunderds of anti virus, malware and other scans to no avail. Deleted history, defrag and unloaded and reloaded Windows 7. I'm this close to get a 3.1 computer which is light years faster with less hang ups.
