Hi, PZEROFGH has given you a solution for your problem, allow me to re-enforce what you said about backing up bios. ALWAYS backup, no matter what, always. I don't know how many times I've had to fix a problem like this, and it is avoidable. Anyway, I learned the hard way, just like you and I wish you success in fixing the issue.
Also, do some research before flashing bios, it's not a task to be undertaken by those without a prior understanding of it.
I\'m already visualizing the duct tape over your mouth...
