Reset Your BIOS

Did you recently upgrade your PC, change its components, or test a setting in the BIOS that now stops it from power up all the way? Here's how to reset your BIOS.

First of all, if you have, read the manual to the motherboard and look for BIOS or CMOS Reset.

Generally, the easiest and least fiddly method is to remove the power cord from the computer, open it and look for a button battery (usually bigger than the ones in a watch) remove it for for five or ten minutes. Theoretically this should work.

If no manual is handy and removing the battery did not work try the following methods:

METHOD 1

1. Power down your PC.
2. Open your CPU
3. Find the 3-pin jumper near the power supply on the motherboard, typically labeled "clear cmos" or "reset bios".
4. Remove the jumper from the default position (typically connecting the 1st and 2nd pins).
5. Replace the jumper to connect the 2nd and 3rd pins.
6. Push the power button on the front of your PC once.
7. Wait a minute.and switch off again 
8. Return the jumper to its default position, connecting the 1st and 2nd pins.
9. Power on your PC with its front power button.

METHOD 2

1. open Command Prompt , click Start Menu > Run > type CMD (enter).
2. type debug (enter).
3. then type this bellow code

o 70 10

o 71 20

type quit.

exit.

METHOD 3

1. Open the CPU
2. Remove the CMOS battery. This should be a regular 3V, round, flat watch battery.
3. Wait at least 5 minutes.
4. Reinsert the CMOS battery.
5. Move the rocker-style switch at the back of your PC (if applicable), to the on (I) position.
6. Power on your PC with its front power button.

METHOD 4

1. Turn on your computer and press the key on your keyboard to enter the BIOS. This is typically the Del (delete) key. Pre-built systems from major manufacturers may use a function key such as F1, F2, or F10.
2. Go to the last tab or page of your BIOS.
3. Select an option similar to "restore factory settings".
4. Save your changes and confirm your selection if necessary. This will often be combined with the process of exiting a BIOS. Some BIOS types may have this as a separate option such as "F10: Save Changes".
