Your speakers might be causing a short circuit in your PC due to electrical issues or faulty connections.
I experienced a problem where my computer would shut down unexpectedly during startup and then fail to restart. I suspected the loose wire at the back of the power supply might be the cause, so tightening it often resolved the issue—probably because my mom sometimes cleans dust behind my desk while dusting. This kept happening repeatedly. When I moved the PC around to see if it would work, it didn’t, which made me think something might be short-circuiting or the PSU was malfunctioning (it’s an 800W Chinese model). I also checked the home’s grounding and all the power outlets, but everything seemed fine. My focus shifted to the speakers first since they worked when I checked them, but I’m still unsure whether it was the speakers or the PSU that caused the problem.
It seems there are multiple potential reasons for the issue. The unplugged power cable, faulty power supply, electrical tape wires, and improper wiring in the house could all be contributing factors.
Yes, I've noticed USB hubs causing short circuits in computers, but I've never heard of speakers doing the same. That's why I was puzzled. Also, after inspecting the loose cable, it looks fine—it wasn't damaged, so I assumed moving the PC around would help.
To join two wires safely, don’t simply connect them and secure with tape. Opt for correct connectors such as marrette wire connectors or butt splice connectors. If the outer covering on a wire is compromised, remove that section and attach the connector to link the cables. Once connected, apply electrical tape if needed. Note that the tape’s insulation might not fully prevent the wires from touching.
