You may want to provide a bit of details here, what is the brand/model of the system, why were you playing around with your drivers? You have a broken monitor, why do you expect it to work? You may want to provide a bit of details about the system. Don't know why you would reset the BIOS to fix a driver issue unless you had no image at all and needed to get it back.
