Diagnosing a GPU Failure: A Journey into Hardware Troubleshooting

When hardware issues arise, frustration can quickly set in, especially when your partner’s computer suddenly goes dark. Recently, I encountered such a predicament with my wife’s PC, which unexpectedly shut down and refused to power back on. I’m sharing our experience in hopes that it helps others who find themselves in a similar situation.

The Problem: A Sudden Shutdown

One day, while my wife was using her PC, it abruptly turned off and wouldn’t turn back on. Pressing the power button resulted in a fleeting burst of activity—the fans whirred for a moment before everything fell silent once more. My first instinct was to troubleshoot the components, starting with the graphics card.

Taking Action: GPU Removal

I decided to remove the graphics card, an EVGA GTX 950, and switch to the integrated graphics processor (IGPU) on the motherboard. To my relief, the system booted up without any issues. This led me to reinsert the GPU and attempt to power on the computer once again. Unfortunately, the machine remained unresponsive, leading me to suspect that the GPU might be the culprit.

Next Steps: Considerations Beyond the GPU

While my inclination was to blame the GPU, I took a moment to consider other possibilities. I inspected the card for any visible damage, such as burnt areas or blown capacitors, though my expertise in identifying such issues is limited. It also crossed my mind that the problem could potentially lie with the PCI-E slot or the power supply’s 12V rail. To avoid prematurely concluding that the GPU was at fault, I sought advice on further diagnostic steps.

A Community Response: Testing and Validation

After reaching out to other tech enthusiasts online, I received valuable insights about how to confirm the health of the GPU. These suggestions included testing the card in another functioning system with reliable components, which could provide clarity on whether the GPU itself was malfunctioning.

The Verdict: Confirmation of GPU Failure

Ultimately, I followed through with the advice given. I connected the GPU to my own computer—one known for its stability with all functioning parts. To my dismay, upon pressing the power button, the GPU indeed failed spectacularly, confirming it was beyond salvaging. Thankfully, the rest of my PC remained intact after this test.

In Conclusion

This experience highlights the importance of thorough troubleshooting and seeking advice from the community when faced with hardware issues. If you find yourself in a similar
