Evening,,
I've driven myself into a wall, I'm desperate
TLDR : PC barely show any signs of life except during very specific hours
First of all, obligatory system specs :
CPU : Ryzen 5 2600
Mobo : B450 Steel Legend (was MSI X370 SLI Plus)
RAM : T-Force Delta R DDR4 3000 32 (16x2) GB RGB
GPU : Yeston RX 6800 XT
SSD : Samsung PM1725a 1.5 TB
HDD : An old 500 GB Seagate Momentus Thin
PSU : Seasonic S12G Gold
Cooler : Cryorig H7 QL
Case : some random chinese $20 case
So long story short, I have this B450 Steel Legend motherboard just sitting around upstairs in an unused PC, so I decided to replace my own PC's motherboard with the B450. The B450 worked well before this, it used to be installed on my cousins PC who since have moved (before I installed the B450 motherboard into my PC, I tried booting up my cousin's PC, no problem).
Anyway, here's the head scratcher :
After installing everything, the PC refuses to boot. When the PSU is switched on, only the RGB lights on the motherboard lights up (and the cooler lights), but the PC won't turn on at all. Power button, restart button, even shorting the front panel headers does nothing. It just refuses to boot under any circumstances. I'm sure the other parts in the PC is fine, it's working just fine before I replaced the motherboard with the B450 just short moments ago.
The weird part is, the PC would turn on by itself for absolutely no reason near midnight. Like I said, it's possessed I'm telling you. When the PC mysteriously turns on, it works fine. The power button work, the reset button too, RGB lights etc. Everything works perfectly. I can shut it down and the PC would turn on with the press of the power button with no problem at all, as long as it's near midnight. Then the PC would refuse to boot again when it's not at the "magic hour", showing no signs of life (except the RGB lights), with the power button / header not functioning, nothing turns it on. Then come midnight (around 11 pm) and it would boot by itself and starts working again until I shut it down outside the "magic hour", in which the cycle continues.
I've never seen this sort of problem, it looks like the PC is in some sort of timer in which it will boot at certain time but not outside it. This means everytime I wanted to use the PC, I would have to wait until "the demon" kicks in and boot the PC for me.
I've tried everything by the book, triple checked everything (trust me, I had 2 days to work with it), some things I've tried :
Reinstalling my old X370 motherboard into the PC boots it up normally, so again I know it's not the other parts. Heck, the B450 motherboard was a reliable workhorse when my cousin was still using it, it ran almost 24/7 no problem (he rarely shut it down). The entire problem only appeared right after I "transplanted" the B450 into my PC.
Any input is welcome, I'm starting to think the moon phases has something to do with the ability of my PC to boot.
EDIT : Accidentally wrote "removing CMOS clock" instead of "removing CMOS battery",, fixed

I've tried everything by the book, triple checked everything (trust me, I had 2 days to work with it), some things I've tried :
- Tried different CPUs (R5 2600, R3 2200G, R3 1200)
- Different RAM kits (8GB Tforce, 32 GB Tforce, and everything in between)
- Different SSDs (an Adata and my Samsung)
- Different GPUs (6800XT and Vega 56)
- Different PSU (Seasonic and a FSP PSU)
- Different case (including no case)
- Resetting BIOS countless times, removing CMOS battery
- Rebuilding the entire thing from scratch, 3 times
- Using different screws to screw the motherboard to the case
- Trying to boot with the least part installed (CPU and the cooler, CPU and RAM, CPU, RAM, and GPU, and all sorts of combinations)
- Reinstalling the motherboard back to my cousin's PC (same symptoms weirdly)
Reinstalling my old X370 motherboard into the PC boots it up normally, so again I know it's not the other parts. Heck, the B450 motherboard was a reliable workhorse when my cousin was still using it, it ran almost 24/7 no problem (he rarely shut it down).
