BIOS error correction steps

If your system has a BIOS error, this procedure will help you fix it. If the BIOS update process fails, your system will be unavailable until you replace the BIOS code. You have two options: install a removable BIOS chip (if the BIOS is in the socket chip). Use the BIOS recovery function (available on many systems with a surface or BIOS chip installed).

How do you know if your BIOS is corrupted?

One of the most obvious signs of a damaged BIOS is the lack of a POST screen. The POST screen is a status screen that is displayed after turning on the PC and displays basic information about the equipment, for example B. The type and speed of the processor, the amount of installed memory and the data of the hard disk.



A computer is a very complex machine. When equipment fails or is damaged, many different symptoms may appear, but not all of them directly indicate a real problem. Hardware problems can lead to unexplained error messages, poor performance, and devices that do not function properly or that do not appear at all. If a hardware component is required for basic computer operation due to a BIOS failure, the computer may refuse to start.

BIOS stands for Core I / O. This is the very first thing a computer accesses when it is turned on. The BIOS provides the computer with all the information it needs to work: such as memory, hardware, and basic processor settings. The boot process used by the BIOS is called POST. The BIOS is located in the ROM chip (read-only), which is installed directly on the motherboard. In most cases, the BIOS chip is installed in a removable outlet so that it can be replaced. Information in the BIOS can often be updated and changed by a process that doesn’tCalled flash memory.

Because the BIOS first enters the computer at boot time, symptoms of BIOS failure or damage usually occur during POST. Strange error messages may appear, or the hardware may not be recognized correctly. Another symptom of a BIOS problem is the computer's RAM, which is usually counted during the POST procedure, does not count properly, or generates an error message during the count. The most common sign of BIOS corruption or failure is that the BIOS simply rejects the POST. If the computer turns on but does not start, there may be a problem in the BIOS.

BIOS problems can be resolved by checking the settings in the BIOS settings menu. This can be done during the POST procedure by pressing the configuration key, usually “F2” or the “DELETE” key, when prompted. The ability to access the BIOS setup usually indicates that the BIOS is working correctly. Check your BIOS settings to make sure there are no problems with the wrong settings. You can also try resetting the BIOS by changing the correct jumps PCs on the motherboard. For reset instructions, see the documentation that came with your computer or motherboard. If you recently tried the BIOS firmware, it may have ruined the BIOS. If you try to use flash memory again, it will usually overwrite all corrupted data from the previous flash memory and solve the problem. Finally, on many motherboards, the BIOS chip can be replaced as a last resort if the chip itself is broken.

If the problem is not directly related to the current BIOS flash memory, the likelihood that the BIOS chip is causing the problems is very small. The signs and symptoms of a BIOS failure or damage are the same as with other hardware errors, such as a memory or motherboard. Try to eliminate some hardware errors before restoring the BIOS.



What to Do When BIOS stops working?

If you cannot access the BIOS setup at boot time, follow these steps to clear CMOS:
  1. Turn off all peripheral devices connected to the computer.
  2. Unplug the power cord from the AC source.
  3. Remove the computer cover.
  4. Locate the battery on the map.
  5. Wait one hour and reconnect the battery.
