I want to do a clean os installation in my hp 425 but can't access the bios. Everytime I go into the bios, I'm prompt with "User ID: bios administrator" and when i enter the password 3 times incorrectly, it says authication failed". I reset the cmos , hold the power button down for 1 minute without any power on but nothing works. Can someone please help me remove this password or tell me the default password for this please. Greatly appreciate it !
