Troubleshooting a Failed Graphics Card: A Personal Experience

In the world of PC building and maintenance, encountering hardware failures is an unfortunate reality. Recently, I faced a challenging situation when my wife’s computer suddenly powered down and refused to turn back on. Below, I’ll share how I diagnosed the problem and ultimately confirmed that the graphics card was to blame.

The Initial Diagnosis

One day, my wife’s computer decided to power off unexpectedly. Following this incident, I encountered a perplexing issue: the system would attempt to start up only to shut down almost immediately. After a series of unsuccessful troubleshooting attempts, I decided to eliminate the GPU from the equation. I removed her EVGA GTX 950 graphics card and switched to the integrated GPU (IGPU) on the motherboard. To my relief, the system booted up smoothly.

However, when I reinstalled the GTX 950 and powered on the system again, all signs of life vanished, leading me to strongly suspect that the graphics card had failed.

Investigating the Graphics Card

To further my investigation, I took a close look at the graphics card. I searched for any visible damage, like scorch marks or swollen capacitors, but my inspection yielded no signs of distress. While it’s important to note that I’m not an expert in identifying hardware failures, I couldn’t help but consider that the issue might also reside in the PCI-E slot or possibly even in the power supply’s 12V rail.

Seeking Confirmation

At this point, I wanted to be certain that the graphics card was indeed the culprit before making any final conclusions. This realization led me to seek advice from knowledgeable individuals who could provide insights on alternative troubleshooting steps or tests that would confirm, without a doubt, whether the GPU was defective.

The Final Test

In a bid to put my suspicions to rest, I decided to test the graphics card on a different machine, one that was known to function well. Upon plugging in the GTX 950 and attempting to power it on, the situation escalated rapidly—the card failed immediately, which erased any doubts I had about its status. Fortunately, my primary PC remained unharmed, confirming the graphics card was indeed the source of the problem.

Conclusion

Experiencing a hardware failure can be frustrating, but with systematic troubleshooting, it’s possible to diagnose the issue. In this case, I learned a valuable lesson about the importance of thorough testing and the potential risks involved in working with seemingly functional components. If you find yourself
