Fans work, but no display on monitor, no light on mouse.
Fans work, but no display on monitor, no light on mouse.
Hello, I’m experiencing issues with my PC. Pressing the power button causes the fans to spin, but nothing appears on the screen and the RGB mouse doesn’t light up. When I try to shut it down using the same button, it won’t turn off at all—it seems stuck in some kind of standby mode.
I began the case, and it suddenly started. What's going on? This cable looks unusual—what is this cable guy who fixed my PC leaving it behind? It seems to be coming from the GPU, probably through a 8-pin connector.
Your photo shows a slightly blurred image of a floppy drive power connector. It seems you have an old, non-modular power supply with many connectors for custom setups—this is likely the one you're seeing. If you don’t have a floppy drive, it remains unused inside your case. Unless something caused a short circuit (unlikely), it probably isn’t the source of your problem. I’d inspect the wiring around the cover to confirm no damage. A possible short from someone cutting into the lid could explain the issue. If you don’t spot any damage, we’ll need more details to proceed further.
