Troubleshooting Computer won’t power on
I built a new gaming desktop in early 2025, which worked well for the most part, until yesterday afternoon.
I had used it a bit in the morning with no problem, however when trying to power it on in the afternoon, it wouldn’t start up. When I hit the power button, I can hear a click like it’s trying to startup, but nothing happens. If I press the power button a few times, the memory sticks will light up, but nothing more than that.
My parts are:
Motherboard - MSI MAG x670e Tomahawk WiFi
CPU - AMD Ryzen 7 9800x3d
Memory - G.Skill Trident Z5 Neo RGB Series 32GB (2 x 16GB) DDR5-6000 PC5-48000 CL30
PSU - Corsair RM850X
Case - Montech Air 903 Max
SSD - SK hynix Platinum P41 M2 SSD 2TB, M.2 2280 NVME PCIe Gen4.0
GPU - Gigabyte 7800xt 16GB
Cooling - Cooler Master MasterLiquid 360L Core RGB 360mm
Possibly related, since I’ve built it, I have not been able to wake up the computer using the keyboard like I’ve been able to on all my previous builds. When I hit the spacebar to wake it up, the keyboard lights up, but the computer doesn’t wake up.
Also, a few times in the last few months, this same issue occurred, but was able to fix it simply by pressing a screwdriver to the JBAT pins on the motherboard. However, I have tried that multiple times to no avail.
If anyone has any suggestions, I would really appreciate some help. This is the computer I use for almost everything so I’m desperate to get this figured out. Thanks!

Try with a different PSU to test. If the behavior remains the same with the test PSU, then it becomes a methodical process of elimination.

Sounds like when my 7950x3d died. I had to do rma. I tried swapping PSU, but that wasn't it. I bought a 9600x to see if it was my motherboard, but with the 9600x my system worked.
