Stuck on BIOS Screen: Troubleshooting Guide

Introduction: Being stuck on BIOS screen is a frustrating scenario – your computer powers on but gets stuck in the firmware (BIOS/UEFI) interface or logo, never loading Windows. This problem can happen on any PC or laptop, and it typically points to an underlying hardware or configuration issue. In this comprehensive guide, we’ll explain why a PC might get stuck on BIOS screen and walk you through effective DIY troubleshooting steps to resolve it. Our goal is to save you time and stress by helping you fix the issue yourself if possible, and to know when to seek professional help. With over 15 years of IT repair experience, Esmond Service Centre (ESC) has encountered countless “stuck on BIOS” cases – our experts share proven solutions and insights below.

A typical BIOS menu screen (Boot settings). If a computer is stuck on this BIOS screen, it indicates a boot process problem preventing Windows from loading.

One common cause of a PC getting stuck on BIOS screen is peripheral or hardware conflicts. External devices (USB drives, printers, external hard disks, etc.) and loosely connected internal components can interfere with the boot sequence. In fact, peripherals like a mouse, keyboard, or USB drive have been known to cause the stuck on BIOS screen issue by conflicting with system initialization. Similarly, if components like RAM or the graphics card are not firmly seated, the motherboard might halt at BIOS.

Steps to Try:

• Power Off and Unplug: Shut down the PC and disconnect the power cable. Remove all external devices except the keyboard and monitor.
  
  

• Inspect Connections: Open the computer case (for desktops) and gently check that RAM modules, GPU, and storage cables (SATA/Power cables) are securely attached. Reseat any loose components by removing and reinserting them.
  
  

• Boot Without Peripherals: With internal connections secured, power on the PC with no external peripherals plugged in. See if it now passes the BIOS screen.
  
  

• Isolate the Culprit: If the PC boots normally, one of the peripherals was causing the conflict. Connect your devices back one at a time, restarting each time, to identify which device triggers the stuck on BIOS screen issue. Replace or avoid using the faulty device.

Why This Works: Disconnecting externals and securing internal connections eliminates potential hardware conflicts. The BIOS performs hardware checks at startup – a bad USB device or an improperly connected component can stall this process. By removing peripherals and ensuring components are properly seated, you allow the BIOS to complete its checks and proceed to boot. This basic fix often resolves cases where a simple conflict or loose connection was keeping the system stuck on BIOS screen.

Incorrect BIOS settings are another frequent reason for a PC being stuck on BIOS screen. Notably, a wrong boot order (boot sequence) can prevent the system from finding a bootable operating system drive, effectively trapping you in BIOS. For example, if the BIOS is set to boot from a USB or network that isn’t present, the PC may not progress. Similarly, certain BIOS configurations (legacy/UEFI mode mismatches, enabled “fast boot” or virtualization settings) might cause boot issues if misconfigured.

Steps to Check Boot Settings:

1. Enter BIOS Setup: Restart the computer and immediately press the required key to enter BIOS (common keys are Del, F2, F10, or Esc depending on your motherboard).
   
   

2. Load Default Settings: Once in the BIOS menu, find the option to “Load Setup Defaults” or “Optimized Defaults” and apply it. This resets the BIOS settings to a stable default state.
   
   

3. Check Boot Priority: Navigate to the Boot Order or Boot Priority section. Ensure your primary hard drive or SSD (the one with Windows installed) is listed as the first boot device. If an incorrect device (like an empty DVD drive or USB) was first, adjust the order so the system drive is first.
   
   

4. Save and Exit: Save the changes (usually by pressing F10) and restart the PC.

Why This Helps: Resetting to default BIOS settings clears any misconfigurations that might have been preventing boot (for instance, accidental changes or BIOS updates that altered settings). An incorrect boot order is a well-known cause of being stuck on BIOS screen, because the system might be trying to boot from a non-bootable source. By ensuring the correct drive is prioritized, you enable the BIOS to hand off control to the operating system loader on that drive. Often, simply loading defaults and fixing the boot sequence resolves the issue and allows the PC to continue booting normally instead of being stuck on BIOS screen.

If basic settings adjustments didn’t work, the next step is to clear the CMOS, which is the memory chip that stores your BIOS configuration. Clearing CMOS (also known as resetting the BIOS) will revert all BIOS settings to factory defaults by physically draining the CMOS battery or using a motherboard jumper. This can resolve deeper firmware issues – for example, if the BIOS got into a weird state or a recent change is causing the boot hang (leaving your computer stuck on BIOS screen). Problems or corruption in the CMOS data can directly affect startup, so resetting it is a powerful troubleshooting step.

How to Clear CMOS:

• Power Down and Unplug: Shut down the PC and disconnect the power cord. Ground yourself to avoid static discharge.
  
  

• Access the Motherboard: Open the case and locate the small round CMOS battery on the motherboard (looks like a coin cell).
  
  

• Remove the Battery: Gently remove the CMOS battery from its slot. Wait about 5–15 minutes to ensure the CMOS memory resets (some motherboards have clear CMOS jumpers – you can use that as an alternative per your motherboard manual).
  
  

• Reinsert Battery and Boot: Place the battery back in its socket (or reset the jumper) and plug in the PC. Power it on and see if the BIOS screen issue is resolved.

Why This Works: The CMOS battery preserves BIOS settings (like boot order, date/time) when the PC is off. By removing it, we force the BIOS to revert to default settings at the next startup. This can clear any incorrect setting or glitch that was keeping the machine stuck on BIOS screen. Essentially, it gives the BIOS a “fresh start.” After a CMOS reset, you will need to re-enter any custom BIOS settings (if needed), but in many cases the system will boot normally again if a CMOS issue was the culprit.

Another reason you could be stuck on BIOS screen is hardware failure in critical components like RAM or the storage drive. Faulty RAM modules or memory slots often cause boot freezing – the system cannot proceed if it detects memory errors. Likewise, a malfunctioning boot drive (the hard disk or SSD with your OS) can prevent the BIOS from handing off control to any operating system. The BIOS may get stuck if it cannot communicate with the drive or if no valid OS is found.

Troubleshooting Steps:

• Test RAM Modules: If you have multiple RAM sticks, try booting with one stick at a time. Power off, remove all but one RAM module, and then try to boot. Rotate through each module and each slot. If the PC boots with some sticks but not others, you’ve identified a bad RAM module or slot. Replacing the faulty RAM can fix the BIOS freeze.
  
  

• Check for Drive Detection: Enter the BIOS setup and see if your primary storage drive is recognized in the SATA/M.2 storage list. If the drive is missing, the PC might be stuck in BIOS because it has nowhere to boot from. Reseat the drive’s cables (for SATA drives) or reinsert the drive (for M.2 SSDs) and check again.
  
  

• Try a Different Drive: If possible, connect a different hard drive or SSD that has a working OS, or use a bootable USB drive. If the computer boots from alternate media, your original boot drive may be faulty. You may need to replace the drive and reinstall Windows if it has failed.
  
  

• Listen for Beep Codes: Some motherboards emit beep codes on boot failure (e.g., a certain pattern for RAM errors). Refer to your motherboard’s manual if you hear beeps – it can hint at which hardware is problematic.

Why This Works: Eliminating bad RAM or drives is crucial because no amount of BIOS tweaking can help if a core component has failed. Memory issues are a common cause of BIOS boot problems, since the BIOS tests memory early on. By identifying a bad stick and replacing it, you restore normal boot functionality. Similarly, if the BIOS can’t detect a bootable drive, it will loop on BIOS screen. Ensuring a healthy drive with a proper OS is present allows the startup to progress beyond BIOS (no more stuck on BIOS screen). These advanced checks might require additional hardware or technical know-how, but they address deeper causes of a system being stuck on BIOS screen.

If you’ve tried the above and still find your PC stuck on BIOS screen, more advanced solutions may be necessary. Two possibilities to consider are a BIOS firmware update and a Windows bootloader repair or reinstallation. An outdated or corrupted BIOS can occasionally cause boot issues – manufacturers sometimes release BIOS updates to fix bugs including boot conflicts. Additionally, if the BIOS passes control to the drive but Windows fails to start, the issue might be a corrupted OS or bootloader (though in that case you usually get an error message rather than a stuck BIOS screen). For completeness, and especially if you see an endless reboot into BIOS, these steps are worth exploring:

• Update the BIOS: Visit your motherboard or laptop manufacturer’s support site and check for BIOS updates. Download the latest BIOS file and carefully follow their instructions to flash the BIOS (often using a USB drive or within the BIOS’s update utility). Caution: BIOS updating should be done carefully to avoid power loss or errors. A successful update can fix compatibility issues (e.g. with newer hardware) and resolve certain BIOS-level bugs. If your BIOS was heavily outdated, this might solve the stuck on BIOS screen problem.
  
  

• Repair or Reinstall Windows: Create a Windows installation media (USB) and boot from it (you may need to use the BIOS Boot Menu to select the USB). Try the “Startup Repair” tool provided in Windows Recovery to automatically fix boot problems. If that doesn’t help, consider backing up your data (you can attach the drive to another PC if needed) and then performing a clean installation of Windows. A fresh OS or repaired bootloader ensures that a software issue isn’t mistaken for a BIOS freeze.
  
  

• Professional Diagnostics: If none of the DIY fixes work, there could be a more obscure issue (like a faulty motherboard or CPU). At this stage, contacting a professional repair service is prudent. Complex problems such as motherboard firmware corruption or multiple component failures require advanced tools and expertise.
  
  

Why These Help: Updating the BIOS addresses the scenario where the firmware itself had a bug or incompatibility causing it to hang during startup. For instance, USB device conflicts or memory timing issues have been resolved by BIOS updates in some cases. Meanwhile, ensuring the Windows bootloader is intact covers the situation where the BIOS isn’t truly “stuck” but rather unable to hand off to a damaged operating system. By repairing the OS or reinstalling it, you eliminate software corruption as a factor (so your PC won’t remain stuck on BIOS screen due to a missing boot file). These advanced fixes go beyond routine troubleshooting, but they can resolve persistent cases of being stuck on BIOS screen that simple fixes didn’t address.

Sometimes it’s hard to know which approach to try first. Basic fixes are simpler and safe for anyone to perform, whereas advanced fixes might require technical skill or carry some risk. The table below compares basic vs. advanced BIOS troubleshooting methods:
