Inescapable coil whine in Troubleshooting Posted October 6, 2020 6 hours ago, Dutch_Master said: Your system is only 6 months old, so your mainboard is still under warranty. RMA it, ASUS engineers would probably want to know what happened so they can prevent it on later models. You can exclude the GPU and PSU by re-installing your old system temporarily with the components from the new system. If the whining stops, the ASUS mainboard is at fault. Fixing coil-whine is extremely difficult w/o a selection of expensive tools, like logic analysers, scopes and spectrum analysis displays. And even if you have these, they're of little use if you don't know how to use them and where to look and look for. The RMA route is much easier, and cheaper The problem is that I don't have a replacement motherboard and I use my computer every day, so I'm in a bit of a pickle. I might just save up and purchase another one and then resell the one I've RMAed ... That's also the reason why I can't install the same components on my old system ( not all compatible, that old mobo is pretty dang ancient in comparison. ) I think I'll send the GPU to be checked over by the retailer since I won't lose anything if it isn't the issue other than a few days of waiting time, and if they say that's not the problem, I'll ask the people at the shop to check the motherboard for whine when they reinstall it all back in ... It's just weird to me that they said there was no whine when there was no GPU in the system. But that might just be because it didn't draw any power, thus not causing whine from the mobo. But yeah, it's really giving me a headache and I've seen horror stories of people replacing pretty much everything in their system and still having coil whine. I really hope that's not going to happen here, was really excited about this system so this is a big bummer. I'll just have to game with headphones on for the time being and deal with the headaches.
