Hi, I've noticed a while ago that my PSU making a NON rapid and random faint ticking sound. It kind of sounds like the sound of two marbles hitting one another. I checked the PSU and I made 100% sure that the sound is not coming from the fan. There is absolutely nothing abstracting it's path. I'm not sure what to do currently. I've been experiencing this for a long time, but I didn't start caring until I got a BSOD this morning. What should I do at this point?
