I have built my pc during summer and it has been fine until two days ago. It started with a crackling noise and my pc not turning on correctly. It's not my pc case nor the power output as I have tried multiple sockets and my pc buttons do work as I have tested them multiple times. The only way to turn my pc on is to give it a power jolt by shutting down the power through the power output or button on the PSU itself, sometimes it takes multiple tries. I have tried checking the cables to see if everything is correctly connected and it seems to be so. I wonder if it's the cable or PSU itself that's a problem...

Not that kind of crackling wee eddie, google my PSU followed by crackling noises and look at the videos, and no it is not my fan brushing against something. I suspect the cable but looking for more ideas until I get a new cable.
