Something keeps killing my GPUs
Something keeps killing my GPUs
My PC sometimes failed to display any video when powered on. This occurred occasionally (perhaps every few months) and became more frequent before the GPU failed. To resolve it, I would reinsert the RAM, often fixing the issue, then reconnect or reset the power cables—CPU, motherboard, GPU. Over time, it began shutting down after short periods, usually requiring a password to log in. Recently, it stopped working entirely, so I brought it to a repair shop. They noted the system didn’t power off during testing, but mentioned the GPU wasn’t detected in Windows and the HDMI port was faulty (other ports weren’t checked). They didn’t intervene further. I wasn’t sure what they meant, possibly indicating GPU failure. After swapping in an older GPU, video returned temporarily, but after about an hour it froze again. I returned it the next day, and they confirmed both GPUs were dead—testing on another machine. Now I rely on my CPU’s built-in graphics.
I’m concerned about what might have caused the GPUs to stop working. I don’t want another replacement that could fail soon; I’m worried about grounding issues, power supply, or even the monitor cable. The PC isn’t drawing power properly, and I suspect something physical might be interfering. The older GPUs were 1050 Ti and 8800 GS—those are high-end models. If vibrations from moving the table affected them, that could help. Using an extension cord might also play a role. I haven’t ruled out the PSU cable as a possibility, even though the newer GPU didn’t need one. The screen would freeze after hours, and rebooting didn’t restore video. I’m unsure if the monitor connection is the issue or something else entirely.
The brand on the power supply isn't specified in the text. The motherboard appears to be quite old, possibly showing signs of corrosion. It's worth noting that without proper grounding, static buildup can't safely escape, which might explain the issue. You may want to consult an electrician to assess whether grounding is feasible or if a GFCI outlet should be installed. If not, consider upgrading with a surge protector or power conditioner, such as the affordable Furman SS6B available on Amazon. The recurring problem with GPUs could point to either a faulty power supply or inconsistent wall power. If your devices are failing despite being plugged in, addressing the grounding issue first is likely the best step.
I understand my old PC is struggling, though the motherboard was recently replaced five years ago. The power outlet will be grounded, but I’m hesitant about adding another GPU or swapping the PSU right away. I know grounding matters for a computer, but why would it take so long to damage one GPU while protecting the other? I tried connecting the machine directly to the wall in another room during shutdown, and nothing changed much. If the issue is with the house’s power supply, it seems only the GPUs are affected, especially since frequent outages have happened locally.
Let me share a tale. I recently had to maintain my home furnace, which kept cycling on and off in short bursts. It was a high-end model from a reputable manufacturer, and I inspected each part carefully—swapped the flame sensor, adjusted the igniter, brought in a technician from the home warranty for a second look, replaced the gas valve, and even swapped out the circuit breaker with the furnace’s electronic board. I rewired everything meticulously, ensuring all connections were tight and secure.
Over time, the unit would work reliably for weeks before suddenly shutting down unexpectedly. They diagnosed it as a faulty control board but couldn’t pinpoint the exact cause. In my view, such an issue should have affected other connected devices on the same circuit—like basement outlets or the HVAC blower. Yet, the smart thermostat remained unaffected.
Curious, I traced the wiring back to the breaker box and discovered a junction box in the middle of the run. Inside, someone had spliced the cable, leaving a loose ground wire dangling. I replaced the wire nut with a proper splice and fixed the issue. The furnace stopped working, and all my efforts paid off.
The lesson? Electronics behave unpredictably. A single failure can disrupt multiple components. Sometimes, the answer is unclear—just try a basic fix like grounding the outlet or using a surge protector. Also, consider replacing the power supply, as older models like the Cougar VTE are flagged as unreliable. If problems persist, hidden corrosion on old boards might be the culprit.
It’s frustrating when you spend time and money troubleshooting something that seems to have no clear explanation. But sometimes, the simplest solutions—like a basic grounding or a quality power supply—make all the difference.
Alright, well I don't know if that makes me feel better or worse lol. Also didn't know there was a PSU tier list, but hopefully I only have to replace one of those things. Wish there was a way for me to reliably test a PCIe slot without killing a GPU.
