I went into bios settings just then and adjusted the cpu freuquency etc... and now the system won't do anything, the screen doesn't even come on! what do I do??

Surely all I would need to do is reset bios???

Do you know where the Clear CMOS is on your mobo?

Is that the battery?

DO I just take battery out and out back in?

Remove your battery that should clear it
