Power supply cable... (I'm freaking out!)
At first I didn't even know what to think... Then I thought it wasn't anything important, but now I'm starting to freak out.
I am hearing "quiet" buzzing sounds coming out of my power supply. The power supply itself is very new but the cable I'm using is around 5 years old. If I reach to the cable and try to move it, pressing it deeper into the power supply box, the buzzing stops but as soon as I let go of it, the buzzing continues. It's as if the contact between the supply box and the cable is a bit loose, I can feel it while gently moving the cable. There are no other issues with the power except for this buzzing sound, but still I am freaking out.
The cable I'm using now is the same one I used with my old PC, which completely broke down; I had a similar problem with the monitor cable which, in the end, ruined my monitor and the whole PC. There was a shortage and suddenly I could hear and see the sparks on the back of the monitor, right where the cable is inserted. I turned off the PC in time because the monitor was almost caught on fire. Then I bought the current monitor and plugged it in, I tried to boot into WinXP but the RAM slots on the motherboard were completely dead and I couldn't even get to the BIOS. When I was building this new PC I changed everything... Except that power supply cable!
But I've been hearing this buzzing sounds for only a few days now, and just wanted to ask for advice, just in case.
Should I just buy a new cable, or can it be a different issue?
