I've been experiencing occasional electric shocks when using my USB cable to charge Bluetooth controllers, and I'm really worried about the potential damage to my devices. I've noticed that the shocks are stronger when my PC is off; while it's on, the sensation is just a mild tingle, but when the PC is off, it can actually hurt. I don't have any grounding in my house, which I've been told is a common solution. Is there anything else I could try? Can I keep using my PC in this state, or should I address this issue first?

It sounds like you might be feeling shocks due to a lack of grounding. Typically, if that’s the case, you'd notice it when touching exposed metal, like the ports or chassis of your PC. Unfortunately, the main fix is usually installing proper grounding in your home.
Honestly, if the cable is actually shocking you, it might be time to consider a replacement. Keeping a faulty cable around could lead to more serious issues down the line, especially with the age of your PC.
Since your PC is about 7 years old, and you've just upgraded components, it might be worth checking if the new power supply or graphics card is causing any grounding issues as well. Those parts can sometimes introduce problems if not set up correctly.
