Motherboards often include hundreds of settings in the BIOS to adjust the performance and stability of your computer. Many of these settings, when improperly configured, can prevent the computer from booting. The traditional way of resetting the BIOS when it doesn't boot is to open the case and place a jumper on the motherboard or remove the battery for several minutes. Most newer motherboards include a reset button near the peripheral ports. The Gigabyte GA-X58A-UD3R uses this more convenient method.
Power down your computer by selecting "Shut down" in the Windows task bar or press the power button on your case for four seconds. Leave the power cable plugged in and the switch on the back of your case in the "On" position.
Press the "Clr CMOS" button on the back of your computer for five seconds until the computer boots. The button is located with the peripheral ports between a USB port and the coaxial S/PDIF port.
Press the "Delete" key when your computer starts up to enter the BIOS set-up.
- Pressing the "Clr CMOS" button while the computer is powered on could result in data loss.
