I am not able to go to the BIOS. In the first screen it shows the option to go to bios or expressrecovery or boot options, but the keyboaard becomes unresponsive immidiately. ;( I tried booting with a bootable disk but no use. The first screen gets stuck each time. Please help

Itried stupid stuff like taking out the mb baterry and putting it back, and taking out the processor and putting it back again, but nothing worked...
Please help me someone.
Is there anywa to reset the BIOS or disable core unlockers through hardware? any key on the mb to rest it? :S
or may be audio device problem??? not likely :S
