2 Easy Ways to Flash the BIOS When Your Computer Won't Start

When your PC won't boot, it's almost difficult to fix anything, so flashing the BIOS may be your only option.

The basic input and output system of a computer is one of its most important components, and it is extremely sensitive to any changes or adjustments.

Flashing the BIOS simply means upgrading it or restoring it to default settings, which will undo any changes.

Even if your computer won't boot, you can flash the BIOS with the help of this article. So, without further ado, let’s get started.

How to refresh the BIOS when the computer cannot boot?

1. From a bootable USB flash drive or update the BIOS

1. Using another computer or laptop, visit your motherboard or computer manufacturer's website and find the support page.
2. They should list your motherboard or laptop model. In our example, we go to the ASUS Help Center and enter our motherboard model number.
3. Then download the BIOS file.
4. If the downloaded file is a ZIP file, please extract the content.
5. Look for the BIOS file in the contents of the unzipped file and note the location of this BIOS file.
6. Before starting the BIOS flash process, save the BIOS file to an external device such as a USB drive.
7. Boot the failed computer after making sure it is plugged in or the laptop is fully charged and plugged in.
8. After the computer starts, press the keys specified in the manufacturer's instructions to enter the BIOS screen for a BIOS update. F1, F2, Delete, F8, Esc, or other keys can be used.
9. After entering the BIOS panel, start the update process according to your computer model. (To complete the upgrade, you may want to check out a different tutorial on the manufacturer's website.)
10. The BIOS flash can take anywhere from a few minutes to a few hours, and your system will reboot after the BIOS update is complete.

It is important not to interrupt the power supply to your computer; therefore, any interruption may cause BIOS corruption, rendering your computer unusable.

Remember, this is only an option if your computer can boot into BIOS instead of Windows.

2. Remove the motherboard battery to reset the BIOS

1. Unplug the computer from the electrical outlet and shut it down. Make sure to release any remaining power in the machine by holding down the Power button.
2. Remove the side door of the chassis.
3. On the motherboard, look for the CMOS battery. Most motherboards today use flat, round cells that are slightly less than an inch in diameter.
4. Slide your fingers under one edge of the battery and gently pry up. The battery may have some kind of locking mechanism that you need to open.

Although this may seem like a complicated process, by following these steps, you'll find it easy to update or flash your BIOS to get your PC working again.

If none of the other options work, flashing the BIOS may be the answer, don't worry, it won't damage your motherboard if it doesn't break.

Reading the manufacturer's manual will also help reduce the chance of the BIOS flash process failing, so it's a good idea to visit the manufacturer's website and read the information.
