It’s only normal that you would wonder what went wrong when your computer started slowing down, crashing, or failing to boot. The problem can be with the software, but most likely with the hardware. If your system won’t even load the operating system, it can be extremely tough to diagnose hardware issues. The third step is to use BIOS diagnostics. These are necessary for checking your computer's hardware and what’s causing the issue.
Basic Input/Output System is known as BIOS. It’s stored in a small program on a chip in your computer’s motherboard. The first thing that is loaded when you turn on your computer is the BIOS. It ensures that everything from the CPU to memory (RAM) and the hard drive is functioning. Then it helps to load your operating system, such as Windows or Linux.
During this early check, if something goes wrong, the BIOS can display a message or beep a series of beeps to indicate there’s a problem. Although not all hardware malfunctions cause an obvious error, running BIOS diagnostics is useful for that purpose.
Integrated utilities known as BIOS diagnostics are employed for testing your computer hardware. The BIOS or UEFI (a newer version of BIOS) contains several checks. Identifying hardware problems before loading the operating system is the target.
These utilities work by checking every part of the system, including the motherboard, hard drive, and RAM, to ensure everything is running as it should. BIOS diagnostics work at a lower level and can detect problems early on, unlike software diagnostics that run after the machine has been booted.
Since BIOS hardware diagnostics work even if your computer cannot start up normally, they are extremely useful. You will not be able to work with software-based utilities if your machine crashes before Windows boots. BIOS can still work, however, and its diagnostic tools can help you identify the problem.
The primary benefit of BIOS diagnostics is early detection. At times, your computer may not show any severe symptoms of problems until the hardware fails. Early discovery of such problems with BIOS diagnostics enables you to repair them before they turn into severe issues.
The accuracy of BIOS hardware diagnostics is also the reason why they play such a crucial role. They are often more reliable than software solutions since they directly interact with the hardware. An unreliable memory stick can pass undetected by a Windows application, but BIOS diagnostics can detect it instantly.
In case you're having problems such as freezing, random system crashes, unusual sounds, or failure to boot, you should consider performing BIOS diagnostics. These symptoms often show signs of hardware issues.
Precautionarily, it's advisable to occasionally run BIOS hardware diagnostics even if your computer seems to be running smoothly. This is particularly necessary if your computer is old or you've just added new hardware.
Shutting down your computer is the initial step towards learning how to perform BIOS diagnostics. Next, restart it and press the BIOS key consistently as the system boots up. This key usually is F2, F10, F12, Esc, or Del, depending on your computer's make.
The UEFI or BIOS configuration screen will then be displayed. The diagnostics menu is now available. It could be called "Diagnostics," "Tools," or a similar option.
You may select the hardware to test in the diagnostics section. Options for specific tests, such as RAM and hard drive testing, or whole system tests, may be displayed. Choose the desired test and adhere to the on-screen directions. Depending on the hardware being examined, certain tests can be completed in a matter of minutes, while others could take longer.
Once you do it a couple of times, it is easy to see how you are supposed to run BIOS hardware diagnostics. You will know if a piece of equipment is working or not with each test.
Different brands have different ways to access BIOS diagnostics. Here’s a simple guide for a few popular ones:
Dell: Press F12 when the Dell logo appears. Then choose “Diagnostics” from the boot menu.
HP: Press Esc at startup, then F2 to launch HP Hardware Diagnostics.
Lenovo: Press F1 or F2 during startup to enter BIOS. The diagnostics option will be in the main menu.
Knowing how to run hardware diagnostics for BIOS on your specific brand will save you time and effort when issues arise.
The BIOS will output the results when the tests are complete. Your hardware is likely fine if all the tests pass. The BIOS will give you an error code or message if there is a problem. You can frequently look up this code on the Internet or your manufacturer's site.
For example, you can choose to replace your hard disk and back up your contents in case the diagnostic test gives a failure reading. System freezes or crashes can be corrected by replacing the RAM stick in case faults are read from the memory test.
Thanks to BIOS hardware diagnostics, you’ll know exactly which part of your computer is causing problems. This prevents you from replacing parts that aren’t broken and helps you fix only what’s necessary.
BIOS diagnostics are not limitless, though. They are useful, but not all components can be comprehensively tested by all BIOS utilities. They may check if a component is there and that it will power up, but they may not perform comprehensive tests for stability or operation.
Once your operating system has loaded, consider using software to perform detailed diagnostics if the BIOS reports all OK, but your computer still isn't functioning properly.
BIOS upgrades can also improve diagnostic capability. New versions can include enhanced utilities, bug fixes, or support for more modern hardware. It may be beneficial to update your BIOS if your computer is behaving erratically and is out of date.
For BIOS updates, go to the manufacturer's website for your computer. Download the latest one by searching for your model. Update the BIOS cautiously, so read the instructions carefully.
Running BIOS diagnostics regularly will assist you in detecting problems sooner. Just like regular medical checkups, keeping the computer hardware may keep it in good health for several years. Professionals, gamers, and students who heavily rely on their smartphones on a day-to-day basis might find this very helpful.
For the most part, these hardware problems can only be identified by BIOS diagnostics. Along with this, they run at a system level instead of on an operating system, so you can use it for troubleshooting when your computer won’t boot.
Every computer user needs to learn how to run BIOS diagnostics, how to run hardware diagnostics for BIOS. These tools will help you figure out the exact cause in case you need to deal with a failing hard drive, faulty memory, or unexpected shutdowns.
