Computer doesn’t turn on anymore

[iRaizen]

So I’ve had this computer for over 2 years now. It was working fine yesterday and today it just didn’t turn on. No fans. No boot. No lights on the mobo. I tried:

- Switching power cables with the computer in my living room
- Switching power breakers

Since none worked I bought a new PSU. Now It still won’t turn on and I’m getting a blinking Red Light around my chipset. I tried:

- Resetting the CMOS battery
- Replugging all the cables making sure they are on snug
- Replugging the RAM making sure they are on snug

I’m unsure where to go from here.

Corsair 850w (Previous PSU: EVGA 750w)
X370 Killer SLI
Ryzen 5 2600x
RTX 2080

Red light around chipset is normal, it's just RGB lighting.

Make sure your front panel connectors are correct
Make sure 24pin and 8pin power supply connectors are fully inserted (and 8pin is for CPU not GPU)
Try turning on without the GPU in after these (to see if it tries to turn on)

If not try some suggestions in this thread.

So far I tried:

- I got the 24 pin snug into the mobo and the 20 + 8 pin snug into the PSU.

- Recheck and readjusted all the front panel connectors

- I removed the GPU and tried turning it on

- I removed and readjusted my CPU cooler

- I removed the RAM and swapped between A1+A2 and B1+B2

- I removed the CMOS battery for 5mins

Still no fans, no rgb on my GPU, only the red pulsing light on my mobo

If you have that RGB light pulsating it means you're getting power to the board. It sounds like it simply isn't being powered on for some reason.

Did you plug in the 8/4 pin molex into the motherboard for the cpu power? (they are usually near the upper left corner of the mobo) Because I do not know what you mean by stating "20 + 8 pin snug into the PSU."

Most fully modular cables split up the 24pin connector at the PSU.

Okay so I got a new PSU, CPU and Mobo.
Still only getting Mobo RGB. When I press the power button there is a clicking sound from the PSU, the CPU Cooler turns on for a second, but still no boot screen. I initially switched out the EVGA 750w for the Corsair RM 850x, switched out all the cables as well, same outcome. Switched the 2600x/Killer SLI for 3600xt/Rog Strix B450-F, same outcome. Switched out the CPU coolers, same outcome. Cleared the CMOS, same outcome. Removed individual RAM and tried with no RAM (CMK16GX4M2B3000C15), same outcome. I tried jump starting the PC with a screwdriver, same outcome.

Deleted. Accidentally quoted myself.

Try it outside of the case. You've basically switched your entire rig now besides the case.

Are any of the diagnostic lights near the upper left corner of the memory on? (between the cpu and the memory nearest the cpu)
