So I decided to OC my new (to me) PC and was doing it how I normally do, moving the core clock up incrementally while running MSI Kombustor. Gpu temp got up to 80 eventually so I dialled it way back and stopped Kombustor, then a few seconds later my PC started to make a crackling noise. I turned it off for 10 mins and tried turning it back on but the noise was even louder, so I turned and left it off. It’s hard for me to say where the noise is coming from but I think it sounds like it’s from the PSU.
Has anyone experienced this before and have any ideas what I can do? Is it safe to turn on?
Thank you!
