Overclocked GPU still working?
Overclocked GPU still working?
I increased the voltage on my 750Ti and my computer stopped working. I believe the GPU is the issue, but my damaged PC also affected its startup. I couldn't get it running again, so perhaps the problem isn't just with the GPU.
I'm trying to see if it still functions in my new PC.
Could putting the possibly broken 750Ti into my current system cause further damage?
I don't want to ruin both of my computers quickly.
No one can provide a clear solution. It all hinges on the specific damage and the safeguards in place for each part. Usually, they consider typical scenarios, such as inserting an 8-pin PCIe power connector into an 8-pin 'P4' (CPU power) port. However, a shorted circuit can lead to excessive current flow, potentially harming the motherboard, PSU, and connected devices. Many contemporary parts depend on voltage regulation and accept only 12 and 5 volts as input, making them more likely to endure because protective measures will activate (either overvoltage or overcurrent protection on the PSU) before overheating or unsafe power levels are allowed.
Unfortunately, there isn't really any clear guidance in this case. You either take the chance or avoid it. However, if the situation doesn't work and I later reinstall my new GPU into a new PC (replacing the original one from the start), will I still be able to use it?
Eximo :
Not 100% sure what you are asking.
If the components are all good it will work. If a component is bad, it won't. There is a potential for a shorted component to damage other components.
Wowowow wait, so if I put in my damaged 750Ti there is a potential I might also break other components? What components for example? And btw, I don't know if it's shortened, but I overclocked it too much so I fried it.
(and yes that was what I mean, that last sentence of yours)

The extent of the harm was altered by adjusting the voltage beyond its intended range. I believe it wasn't completely damaged since all connections remained intact. Changing the voltage on my 750Ti caused my screen to go dark. After disconnecting power and restarting, my PC experienced significant difficulty and lagged heavily, making games unplayable.
I planned to integrate this 750Ti into a new system where everything functions properly. I was told it should return to its original configuration, restoring any overclocking adjustments (unless physical damage has already occurred).
What are your thoughts on the likelihood of it functioning correctly and the risk of further harm to other parts?
At least: sorry for my delayed response, and thank you for your assistance.
I wouldn’t describe the damage by its nature, but rather by what occurred. The GPU’s condition remains uncertain. If you altered the GPU’s voltage via software and stopped using that software, it will revert to default settings. However, if you changed the GPU’s BIOS to set permanent values, those changes will persist. A short circuit isn’t necessarily about the wiring itself; it can occur anywhere in an electrical path, even at the transistor level. The connections within a PCB or GPU might fail long before the wiring does. To detect a short in a partially functional device, you’d need an ammeter and a known baseline current. If the GPU is overheating excessively due to such a short, it could explain why it becomes unusable. It’s impressive that it still functioned enough to get you into Windows.
If you’re using the old system, try running the GPU there before moving it to a new setup. Any probability would be a rough estimate. Electronics are generally unpredictable—about half the time—and it’s rare to find a component working partially. I’ve only seen a few personal cases in the past twenty years.
1) A CPU that shorted but still operated, with power supplies and ATX connectors failing after a few days. It ran extremely hot, likely because its temperature protection failed. The socket darkened toward the end, and I had to solder wires around the ATX connector.
2) A GPU showing random output problems, sometimes missing a DVI port entirely.
3) A blown PSU fuse that remained connected, dropping voltage from around 12V to about 10V and halting operation.
4) I built a computer where all parts worked individually but together caused massive instability.
5) A motherboard that can no longer recognize any memory slots, even though each slot and module functions properly. It simply fails to address anything above 8GB.
Usually, computers shut down with a loud noise or power cut, almost always due to power supply or circuit issues.
