GPU is generating video output yet remains unrecognized by the system.
Hello everyone, I recently assembled my first PC and it’s performing well so far. Everything seems fine with the drivers, and games are running smoothly. # How it went Last week I connected a mouse and noticed some static when the USB touched the case side. The screen went dark briefly before returning quickly. # The Issue Since then, the HDMI connection from my GPU remains functional, but my PC fails to recognize the graphics card. Performance drops significantly, and I can’t run any games or graphic-heavy tasks. Everything else works, though GUIs are slow. # Troubleshooting Steps I disconnected the card completely from both ends, checked the PSU cables, and plugged it back in. After inspecting everything, the problem persists. I examined the PCIe riser cable for any damage and think it might be the culprit behind the static and subsequent issues. Could this explain what’s happening? If the GPU fans are spinning, the RGB lights are on, and video appears via HDMI but isn’t managed by Device Manager or AMD Adrenalin, what does that suggest? Any advice would be invaluable. Thanks!
Do you see any bare wires on the riser, and could it be that the circuit is active rather than just holding static charge? Is the monitor solely connected to the GPU, or are there other ports involved? You won’t get a display from integrated graphics unless something is connected to the motherboard.
The case is grounded and a mouse has no connection to ground other than the USB port, so I don't see how it can be anything else. Its kinda unusual this would happen at all with a mouse, it usually happens when you connect a USB device with its own PSU due to them not having a true earth connection so when you connect to the REAL earth of the PC it causes a spark as the devices ground plane is pulled to REAL ground. I would constantly get small shocks when plugging in USB HDDs due to this, but its not damaging anything. While that doesn't look good, I kinda doubt its related as it doesn't look like the internal cable is damaged, just the outer sheathing.
The situation being grounded is puzzling, but I’m guessing static electricity wouldn’t accumulate under that scenario—though that’s not a joke. It’s really confusing what happened and I’m still trying to figure it out.
Sure, just let me know what specific details you're looking for about SecureCake.
