Sometimes it is necessary to reset your PC's BIOS
Whenever you make adjustments to your PC's BIOS (or Basic Input Output Operating System), you run the risk of your computer not turning on, or not functioning the way you would like it to. In order to fix this problem it is necessary to reset the PC's BIOS. Here's reset a PC BIOS.
Instructions
1. First we will assume that you are still able to access your PC's BIOS. On most computers, you can access the PC BIOS by pressing the Del key when the computer turns on. This should bring you to a screen with many options, your PC's BIOS. From here you should flip through the options until you find the option to reset a PC BIOS to the default settings.
2. If you cannot turn on your PC due to problems with your BIOS, you need to reset a PC BIOS... but how? The BIOS information is stored even when your computer is turned off via the CMOS battery. There are two ways to clear the information on the CMOS battery and reset a PC BIOS.
3. The first way to remove the memory on the BIOS is to use the jumper pins on the motherboard. Make sure you first unplug your PC's power supply. There are three pins near the CMOS battery that will say "CLR_CMOS" or "RESET BIOS". Move the jumper over one pin so it is on the middle pin and the pin it was not on previously. Press the power button on your computer and wait a few minutes. Return the jumper to its original location. Plug your PC's power supply back in and turn on your computer. Your PC BIOS should be reset.
4. If your BIOS still does not work, I find this method the most reliable, though somewhat difficult. Unplug your computer from its power source and remove the CMOS battery. It may be a little difficult to pry out, so be careful not to break anything. You may want to try to use a flat-headed screwdriver. Once the battery is out, keep it out for several minutes (lets say five minutes just to be safe). This will definitely reset a PC BIOS to its original settings. Return the CMOS battery to its original slot, and turn your computer back on.
