Question PC not booting after changing position of AIO

[misterdeege]

I built my first full PC about two months ago, all parts are brand new. Everything was fine until my AIO started making a loud grinding noise yesterday, so I figured that it was time to shut down the PC and try to fix the issue. I was playing Cyberpunk at the time, and temps got up to the high 90s. I figured that perhaps the pump was trying to push air, so I tried mounting it on the top of my case (instead of the side) to try to get the air out of the pump. But now, when I try to boot the computer, it does not boot. All components light up (GPU, AIO, fans, motherboard, etc...) but none of the peripherals (monitor, keyboard, mouse). Upon turning the PC on. The AIO also still occasionally makes that noise, but quieter (sometimes it doesnt make any noise at all). The DRAM light flashes then turns off, the CPU light then flashes and turns off, then both again, then the DRAM light stays on. Ive tried to reseat the CPU, clearing the CMOS, and reseating the RAM (all slots using 1 stick). I cannot for the life of me figure out what is going on. In fear of a dead AIO (which would be weird since I got the thing just 2 months ago) I've only allowed the PC to try to boot for a short amount of time, then turning it back off. I know I'll probably have to get a new AIO, but the PC should still at least boot, right?
Specs:
CPU: Ryzen 7 7800x3d
Motherboard: Gigabyte B650 Gaming X AX
Memory: 2x16 G.Skill Trident Z5 RGB
CPU Cooler: Lian Li Galahad II Trinity Performance
GPU: Radeon RX 6800XT
PSU: Corsair RM1000x

Edit: I also failed to mention that the AIO pump lights stay on even when the PC is off, if that helps at all.

AIO started making a loud grinding noise

Sounds like catastrophic bearing failure. Most likely inside the pump itself.

But now, when I try to boot the computer, it does not boot.

Where is the AIO connected? Into CPU_FAN header? If so, that header must send feedback of RPM back to MoBo, for PC to boot. Else-ways, MoBo thinks CPU cooler is toast and safeguard stops PC to operate.

which would be weird since I got the thing just 2 months ago

Can you tell me the reason why your AIO has warranty?

Yes, the AIO is connected to the CPU_FAN header at the top. I'm glad to know that there are safeguards in place so I don't fry my CPU. Unfortunately, I threw out the box and reciept (like an idiot) so I don't have the serial number or proof to register a warranty. So it looks like I'll just have to save up a bit more and buy a new one. Thanks for all your help.

That's a good life lesson actually.

I'd go with tower-type air cooler (e.g Noctua). Cheaper, far more reliable and in terms of cooling, equal to AIO (since both are cooled by ambient air).
