I was playing BeamNG when my PC suddenly froze. After powering it off with the button, it refuses to boot now. I noticed one of my RAM sticks wasn't seated properly, but it still recognized 96GB of RAM before freezing (which I thought would help with flight sims, even though I don't really need that much).
Here's what's going on: the GPU LED and the LED at the front of the case both work, the power button seems fine, and the fans spin, but the fan LEDs are off. There's no signal to the monitor and no beep codes at all when I try to start it up.
My setup is as follows:
- Corsair CX750 PSU
- Gigabyte B650M Gaming Plus WiFi
- Ryzen 7600X
- RTX 4070ti
- 2x 48GB 5200DDR5 RAM
I've tried several things:
- Removing the power button plug from the motherboard and bridging the gap
- Removing the GPU and routing HDMI to the motherboard
- Taking out and swapping the RAM sticks, testing all 4 ports
- Unplugging everything and plugging it back in.
Unfortunately, none of this has worked. The speaker has not given any beep codes throughout the troubleshooting process. Any advice would be really appreciated. I don't have spare components to test with, and this is my first build, which has been fine for six months until now. Thanks in advance!

It sounds like your motherboard might be fried, especially if you've tried booting with just one RAM stick and the CPU and it still won't POST. It's also possible it could be your PSU causing the issue. You might want to consider resetting the BIOS or even removing the motherboard from the case to check for any grounding issues.

Resetting the BIOS would be a good next step. Also, pulling out the motherboard completely can help eliminate any potential grounding issues you might not see.
