go into your BIOS and try to find the XMP setting and disable it

You got XMP enabled? Try turning that off

An Aio Cooler, my bad. I've checked all the wires and theres nothing hitting any fan blades, but there is a small wire from one of my corsair fans that might be slightly touching the blades but I highly doubt it could be making grinding noise that bad.

My PC has been making a loud grinding noise on startup and immediately goes away after around 2 seconds. The noise does not appear after I close my PC and turn it on again, and only happens when I don't use my PC for a few hours and start it up again. I haven't had any trouble with this noise before I installed a new AIO Cooler and Graphics card but I've stressed tested the fans on both of them and cannot seem to find any noises that are abnormal. However, I've discovered a coil whine/static noise coming from my powersupply and I am wondering if that was the culprit for the loud grinding noise. I have a Corsair RM750x Gold power supply.

I meant no cables are touching the graphics card either, nothing is touching the graphics card

They aren't, no cables are touching the graphics card

Will it harm my graphics card if I leave it like this?
