I loaded Windows 7 Ultimate 32-Bits and then entered my ID and password. Rebooting PC it accepted my password. PC responded with Windows 7. Then loaded Intel CD of "Express Installer Drivers" and rebooted PC. After rebooting PC it refused my Password entry. Then tried to load Windows 7 Ultimate 64-Bits repeating steps one two and got same result again. Would software or media programs offering to replace forgotten passwords obtained on the Internet be helpful? If please indicate which one of the many available. Are there BIOS updates to install that would help? Are there drivers on the Intel CD named "Drivers and Documentation" that need to be installed also? Do you have an manual to download for the Intel Board "DZ77GA-70"? I Booted up to the BIOS and found place where ID and or Password could be changed. So I selected new ID and Password for computer. Rebooted Computer but could not get in Windows-7, or CD, or BIOS. It recommended my sending an email to Intel address of http://support.intel.com/support/motherboards/desktop.
Software/Hardware used: Windows 7 64-Bits with Intel Board :DZ77GA-70K (Extreme Series)
