RED Led CPU light on motherboard

[akeech01]

At my wit's end and have read multiple threads already.

Brand new parts:

MSI - B350 GAMING PLUS ATX AM4 Motherboard
AMD - Ryzen 5 1600 3.2GHz 6-Core Processor
Corsair TX 550m power supply
Asus - GeForce GTX 1080 8GB TURBO Video Card
ADATA - Ultimate SU800 512GB 2.5" Solid State Drive

No video output on monitor,
I have benched it and just have the mobo, cpu, heatsink, memory and psu. When I short the power switch and turn it on the red cpu LED is still there. I have reset the bios and reseated the ram but don't know what to do. CPU looks fine when I took it out and checked and power supply is connected correctly. Can anyone please help? Much appreciated!

Make sure your ram is in slots A2 and B2, but just try for now with 1 stick in A2 only, you never said which ram you have.

Also, I know there is no on board graphics, but see if it still gets stuck on the cpu led without the graphics card installed or if it gets stuck on a different led.

Something to note is it is still very possible that it needs A bios update to support that cpu as these boards are only a couple of months old and were only released initially with R7 only support.

Thanks for the answer.

I have Team - Dark 16GB (2 x 8GB) DDR4-3000 Memory with one stick in the A2 position.

I took out the graphics card It's just the PSU, motherboard, CPU and memory right now.

Funny thing is I could get into the bios a couple times at the start but then it would randomly shut down or freeze when I tried to boot from a flash drive with windows. I'll be taking it to a computer repair shop tomorrow to see what they have to say. This is my first time building a PC so I am kind of new to this.

Ahh, if you've managed to get to the bios a few times already, then it's not a bios issue.

One little trick I learned over at the msi website, and you can try this with either the cpu removed or all of them ram is, remove all of your ram, then power on the computer, if you have a speaker plugged into the board you'll hear it beep, switch off, clear the cmos, but use the jumper on the motherboard, then put only 1 stick in and try and start again, try this with the cpu too.

When clearing the cmos, try a couple of different tools on the jumper pins, car key, kitchen knife, flat head screw driver etc, sometimes one will work and the other won't.

Don't try and get your ram upto speed in the bios yet, first thing I would do when you get to the bios is update it, just leave everything at stock settings, also whilst trying to install Windows, leave everything at stock settings, mess with ram speeds etc once you've got Windows on and the bios updated.

I have the same issue with my X470 Gaming Plus, tried different RAM, 1 RAM stick, even a new PSU. The CPU led is red, no POST, resetting CMOS, the Jumper, etc no video signal. Gonna try a new CPU.
