Computer post and black screen 2 -3 second after entering windows or ubuntu intstallation

Troubleshooting Black Screen Occurs Briefly After Windows or Ubuntu Installation Initiation

Introduction

Many PC enthusiasts and users encounter perplexing issues during OS installation, such as the system displaying a black screen shortly after starting the process. If you’ve experienced your computer posting successfully but then encountering a black screen just moments after initiating Windows or Ubuntu installation, you’re not alone. This article aims to guide you through identifying potential causes and effective troubleshooting steps for such issues.

Understanding the Problem

Typically, the sequence involves the system successfully powering on and entering the BIOS, with all hardware recognized properly—CPU, RAM, storage drives, USB devices, and graphics. However, when attempting to install an operating system, the screen briefly flashes or remains black within 2 seconds of clicking ‘Next’ or beginning installation, preventing progress.

Common Symptoms:

• Successful POST (Power-On Self-Test)
• Correct recognition of hardware components in BIOS
• Black or blank screen shortly after OS installer starts
• No visible errors or messages during the brief black screen

Potential Causes

Several hardware or software factors can contribute to this problem:

• Graphics Compatibility or Driver Issues
• Inadequate or incompatible power supply
• Faulty or improperly seated RAM or CPU
• Storage device issues or incompatibilities
• BIOS settings misconfiguration
• Overclocking or temperature protections interfering

Step-by-Step Troubleshooting

1. Verify Hardware Compatibility and Stability

2. Check that your hardware components are compatible with each other and support the intended OS.

3. Reset BIOS to defaults, ensuring no overclocking or aggressive settings are enabled.

4. Update your BIOS/UEFI firmware to the latest version from the motherboard manufacturer’s website, as updates often fix compatibility issues.

5. Test Components Individually

6. RAM: Test each RAM module individually in different slots to identify faulty modules.

7. GPU: Swap the existing GPU with a known good one, such as your GTX 1080, to rule out graphics card issues.
8. Storage: Use a different storage device or connect via different ports to exclude drive problems.

9. Power Supply: Confirm your PSU provides stable power; an insufficient or failing PSU can cause such issues.

10. Adjust BIOS Settings

11. Disable features like Fast Boot, Secure Boot, and CSM (Compatibility Support Module).

12. Set graphics output to integrated or primary GPU.
13. Disable XMP profiles temporarily to rule out RAM timing issues.

14. Enable or disable certain features like PCIe slots or others that might interfere.

15. Check Physical Connections
