TLDR; a GPU LED light on an Aorus X570 Ultra does not mean that the GPU is dead. My CPU is what died.
Posting this here as Tom's is good with Google Search Results. Someone with the same issue might find it. I wish I had found this while troubleshooting.
My computer just died on me last night; no warning, no BSoD, nothing. It rebooted and then would not start after that. When trying to boot, I noticed that the GPU LED was on permanently. I assumed the GPU was dead. I tried moving RAM sticks around, clearning the CMOS, removing the battery, and was unable to get it back up and running.
I'm running the following:
Motherboard: Aorus X570 Ultra Rev 1
Processor: Ryzen 3900x
RAM: G Skill Trident Z Neo 32 GB @ 3600 MHz (XMP)
GPU: Aorus RTX 2070 Super 8G
This morning I got up and went to Best Buy and sourced an MSI 5500 XT thinking I'd use that until I got the RMA on my 2070S completed. To my surprise, I got the same result and the computer wouldn't boot. This computer is what I use for work and it absolutely needed to be running on Monday (tomorrow). Because of this, I got in my car and drove 50 miles to the nearest Micro Center, where I would be able to buy an entire system and use that to troubleshoot. Worst case scenario, I'd just build a new system and use that to work until I could figure out what was going on with my computer.
At Microcenter, I bought a new Asus X570 motherboard, a new 3900X, and the same RAM sticks I had. I also got a new PSU, just in case, but my current one is less than 6 months old and is a 850W Seasonic, more than enough to handle my system. This and the 5500 XT is a new system and should most definitely work. Came back home and got to work. I was about $1,200 in at this point.
I decided to start with the motherboard, thinking that there is no "motherboard" LED on this board and could likely be the culprit. I've never gotten to a point where I trust it completely for some reason. After completely dismantling my system and putting it back together with the new motherboard, I got the same result. Would not boot.
I have been using and putting together computers for over 20 years and I've never had a CPU just die on me. However, this is what I tried next. I put in the new 3900x on the new Asus board and it fired up and I was able to get into the BIOS. I couldn't believe it.
It was then time to take the whole thing apart, put in my old motherboard, and reconnect everything. Once I did that, I closed the case, connected all the cables and everything worked again.
Tomorrow I will drive back to Micro Center and Best Buy and attempt to return the items I didn't end up needing.
I think it is unfortunate that there is no better way to indicate where the failure of the 4 main components is. Even an LED that says "other" would at least help cross out the GPU as the possible cause, particularly on CPUs without integrated graphics where you cannot test the GPU if you don't have another one around. Does anyone know why the motherboard would have the GPU LED lit but the CPU is what had failed?
Now onto RMAing this CPU.
By the way, the only thing I've done to this CPU is underclocking it to 1.275 volts when I needed this to remain quiet using Ryzen Master. This gave me an all core speed of 4.2 GHZ without temps going insane. I don't know why by default these systems sent up to 1.4 volts to the CPU when idle.
