Troubleshooting a Self-Built PC That Boots Directly into BIOS: A Step-by-Step Guide

Building your own computer can be a rewarding experience, but it often comes with unexpected challenges. Recently, a user shared a common issue where their self-built PC with specific hardware components would Boot directly into the BIOS instead of the operating system. Here’s a detailed overview of the problem, along with practical solutions to help you diagnose and resolve similar issues.

System Specifications:
– Motherboard: TUF Gaming B650-Plus WiFi
– CPU: AMD Ryzen 5 8400F (6 cores)
– RAM: 2x Kingston 16GB DDR4
– Graphics Card: NVIDIA RTX 1050 Ti
– Storage: Kingston M.2 1TB SSD

Problem Summary:
The user experienced a period of inactivity (no use for three days). Upon attempting to boot the system, it resulted in a black screen. After resetting the BIOS, they tried to restart the PC, but it now boots directly into BIOS setup, bypassing the operating system. Despite ensuring the boot drive is recognized and prioritized in BIOS settings, the problem persists. Multiple BIOS configurations, including toggling UEFI and Legacy modes, have not resolved the issue.

Common Causes and Troubleshooting Steps:

Verify Hardware Connections
Power Cables: Ensure all power connectors, especially to the motherboard and SSD, are securely attached.
RAM Installation: Confirm that RAM modules are properly seated in their slots. Try booting with one RAM stick at a time to identify potential issues.
Check Boot Priority Settings
Drive Recognition: Double-check in BIOS that the SSD is detected correctly.
Boot Order: Ensure that the SSD is set as the primary boot device.
Reset BIOS Settings
Clear CMOS: Perform a full CMOS reset by using the motherboard jumper or removing the BIOS battery for a few minutes. This can reset all BIOS settings to default and resolve corrupted configurations.
Assess BIOS Mode (UEFI vs. Legacy)
Switching between UEFI and Legacy modes can sometimes resolve boot issues. Since previous attempts didn’t help, ensure that your operating system installation matches the mode selected.
Inspect Storage Device Health
Drive Status: Use another system or a bootable diagnostic tool to verify the health and functionality of your SSD. A failing drive can cause boot failure.
Test with Minimal Hardware
Remove all peripherals and non-essential components.
Attempt to boot with only
