Troubleshooting Black Screen After PC Crash: A Comprehensive Guide

If your computer is experiencing a black screen after a crash and you believe it to be a GPU issue, this guide will help you identify and resolve the problem. Here are some basic steps and tips to help you diagnose and potentially fix the issue.

Step-by-Step Checklist

If your fans are running, start by checking the following:

Unplug and replug your computer entirely. Check all the cables and ensure they are securely connected. Remove and clean the RAM with a new eraser if necessary.

Common Troubleshooting Steps

First, ensure your computer is properly powered and all components are functioning as expected:

Is your computer plugged in correctly? Is your monitor on and properly connected at both ends? Are all the lights in the cabinet indicators on and functioning? Is the breaker tripped at the outlet?

These steps are the initial troubleshooting measures to ensure your system is receiving power and functioning correctly.

Advanced Troubleshooting Steps

If the basic steps do not resolve the issue, consider the following advanced steps:

RAM and Motherboard Issues

Troubleshoot potential issues with the motherboard and RAM:

Remove all but one stick of RAM and try booting up. Replace the RAM and ensure the golden pins are clean. Reset the BIOS if necessary (refer to section below).

Graphics Card and Motherboard Issues

If you suspect a graphics card issue, try the following:

Try the on-board video to rule out the graphics card. If on-board video works, gauge whether the problem is with the graphics card or the motherboard drivers. Try your monitor on another known working system. Test the graphics card on another known system.

Resetting BIOS

Resetting the BIOS can sometimes resolve issues with your computer:

Locate the jumper on the motherboard near the CMOS. Set the jumper to the CLR (Clear) position and power on the computer. Once the PC boots up, shut it down and power it off. Return the jumper to its previous position to prevent clock resetting.

Conclusion

While these steps can help you diagnose and potentially resolve the issue of a black screen after a PC crash, determining the exact cause can be difficult without more specific details. If you are still experiencing issues, consider consulting a professional or reaching out to your hardware vendor for support.
