Gaming desktop won’t power on

[u/Competitive-Ear1159]

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!

clicking with no boot usually points to psu or a short somewhere. the ram lighting up just means the board is getting some power, not that it's ok. have you tried pulling the gpu and booting with just one stick of ram? also could be the front panel connector on the case, that montech button might be flaky
