I tried to reset my Windows 7 password as I had forgotten it and on instructions from various sites, entered the BIOS, made what I thought were the correct changes then things went downhill fast. I don't know what I'm doing in BIOS but I thought others did and now, when I try to get into BIOS, it requests a password. After about 3 tries, I get the message "SYSTEM LOCKED' Help please = I don't know what I'm doing !!!!
