Troubleshooting a PC Stuck on Boot Screen After BIOS Configuration Changes

Experiencing boot-related issues can be quite stressful, especially when your computer becomes unresponsive after modifying BIOS settings. If your system is stuck on the startup screen following recent BIOS adjustments, this guide offers potential solutions to help you recover your PC and restore normal operation.

Scenario Overview:
Recently, a user made specific changes to the BIOS settings on a B450 PRO WIFI motherboard, enabling features such as 4G decoding and the Resizable BAR. After saving these settings and exiting the BIOS, the system became unresponsive, remaining on the initial boot screen. Attempts to restart or access BIOS again were unsuccessful, and peripheral devices also stopped responding.

Possible Causes:
Modifying advanced BIOS settings like 4G decoding and Resizable BAR can sometimes lead to system instability, especially if incompatible hardware configurations or BIOS firmware issues are present. These settings are designed to optimize performance for certain graphics cards and memory modules but can cause problems if not supported or configured correctly.

Recommended Troubleshooting Steps:

Power Cycle Your System:
Completely shut down your PC.
Unplug the power cable from the wall outlet.
Wait for at least 30 seconds to ensure all residual power drains.
Plug the power cable back in and attempt to power on the system.
Reset BIOS Settings to Default:
Turn off the PC and unplug it.
Locate the CMOS battery on your motherboard (a small coin-cell battery).
Carefully remove the CMOS battery and wait for approximately 5-10 minutes to fully clear the BIOS memory.
Reinsert the battery, reconnect power, and turn on the system.
This process resets BIOS settings to factory defaults, potentially resolving boot issues caused by updated configurations.
Use the Motherboard Jumper:
Alternatively, refer to your motherboard manual for the BIOS reset jumper.
Move the jumper to the clear position, power on briefly to reset BIOS, then move it back to the original position before powering on again.
Check Peripheral and Hardware Connections:
Ensure all cables, RAM modules, graphics cards, and other peripherals are properly seated.
Disconnect any non-essential hardware components to isolate potential conflicts.
Attempt BIOS Recovery:
Some motherboards support BIOS recovery procedures or dual BIOS features.
Consult your motherboard’s manual for specific instructions on BIOS reflash or recovery modes.
