I don't know much about computers, so when I tried installing iTunes, and the computer completely froze, I shut it off manually, and upon restart, accidentally set all of the BIOS settings for my motherboard to defaults, now when trying to boot my computer, it gets stuck at the loading windows screen, I already tried reinstalling Windows 7.. Any suggestions?
