Computer problem?

You will not lose any information by resetting BIOS. One thing you might have to replace is the small battery that keeps your BIOS memory. This is a small silver disk on your motherboard and should have a model number starting with CR. To reset your BIOS you should have a jumper on your motherboard that has a label something like BIOS or CMOS. Move the jumper over, power on your computer, after a few seconds, power it off. Place the jumper back to original position, then power computer up again. Or, just remove the battery for a minute. Good luck!
