Well, I'm about 4 generations behind, so I'm thinking Asus X99 Prime II ---> Asus X570-E (so I can maintain flashback) I7 6800k ---> Ryzen 3 3900x GTX 1080 ---> RTX2080Ti And I might also redo my custom loop and change to acryllic from soft tubing

Try updating your BIOS, if that doesn't work, find a working system to test the GPU in. If the GPU works in the other system, then you might have.a problem with the motherboard.

Looks like a bum SLI cable to me, try and RMA it I guess.

Have you updated your BIOS?

Try upgrading to the latest BIOS

Also, due to the fact it's a REALLY old engine, chances are it doesn't have multi-core rendering or any of the new fancy CPU instruction tweaks so it's probably also limited by that.

Oh yeah, noctua is one of the leading developers of heatsinks. They also specify their TDP dissipation on their coolers so that should help you find one that'll work for you

Also make sure to disable the xbox app in windows under game settings

That might be a problem as already the drive isn't getting mounted correctly, it actually sounds like his HDD controller has given up the ghost from the sounds of it.

Well, first off, the first video you posted shows you tried booting without RAM in. The PC will never POST without ram. Second, make sure that you use the correct RAM slot on your mobo if you're going to use only 1 ram stick.

Well, next option I would try is turning auto-negotiate off on both the switch port and your PC, then setting both to 100 or 1G full duplex and trying that.

@TreyYaBoy I would go look at Noctua's heatsink lineup then, they have some really great low-profile air coolers, they're just a little pricier than regular tower-style heatsinks.

Ah, did some scrounging on the asrock forums and apparently someone had the same issue until they updated their BIOS, so try that too.

Then I guarantee you have a group of SATA ports that are disabled. Have you tried plugging the drives into another computer?

When you say it's an NVME M.2, is it one that plugs into your PCIe slot, or the M.2 slot?
