Hello, So I'm trying to fix my dads computer. It had a bunch of spyware/viruses/etc, I think I got rid of most of them with a combination of spybot, combofix and windows antivirus. When I try to boot up, it regularly freezes during the Windows XP boot screen. I can usually get safe mode to load but it will occasionally freeze in safe mode and require me to hold the power button to turn it off. HP Pavilion 750n Windows XP Thank you.
