EDIT: ended up being 1 faulty ram stick, 1 (supposedly) bad psu, an overcooked cpu, a dead aio cooler and (potentially) a faulty psu. Thanks Linux bros.
I did the memtest. Figured out 1 out of 4 ram sticks are bad and sent it out on an RMA. Took the whole rig to a local shop and he load tested the PSU. It failed twice. He recommended I replace the PSU then the motherboard if I still had issues. So I replaced the PSU with a new unit, still the exact same issues. So I replaced the motherboard with a used one. Still the exact same issues. I updated the BIOS. Same issues but a new, more red Asus logo (yay).
I still cannot, for the love of AntiChrist, boot the thing. At. All. Not even from a usb. Attempting to fresh install windows and i have zero input from any devices.
I am at my wits end and I need my PC back up and running.
Linux bros blocked immediately.
I'm going off just the info in this post. Have you tried a known working CPU? IIRC, both the CPU and motherboard must support TPM for it to work. If it's not the motherboard, then the CPU is the likely culprit. And make sure the CPU is one your motherboard will support even if it has the factory BIOS, just in case.
When troubleshooting, it's best to swap out parts one at a time, individually, with a known working component . Or vice versa; put one of your parts at a time in a known working computer.
I know sometimes that's not possible and you've got to take a best guess, but it's best to know for sure that replacing the part is going to fix the problem else you risk wasting money.
EDIT: And I'm not suggesting the CPU you have doesn't support TPM. I'm just thinking the CPU is messed up in some way that's preventing it from working properly. As if I needed another reason to hate TPM.
I dont have a spare cpu, no. And ive asked everyone i know who has a gaming pc. They all bought pre builts and cannot let me test their cpu (if they even have an amd4).
