Ryzen won't post

I've been banging my head against a wall all week. Started by having issues installing windows but now I can't even post.

Ryzen 1600
Msi b350m mortar arctic
Corsair vengeance lpx 2133 DDR4 2x8

Nothing on screen using my video card or the onboard dvi port.
Tried a single ram stick in each slot.
Usually CPU light stays on. With ram in slot 4 it's the ram light instead of CPU light
I've reset cmos.

All drives are removed at this point.

Has my CPU which was working Now died? I could boot Linux before and briefly had windows running and now nothing.

Please help

  1. I would be looking at the motherboard since it did start up one time.

  2. Also I have never touched any overclocking settings

  3. Try a barebones boot. Make sure both 24-pin and 8-pin connections from your power supply are plugged in to the motherboard. Make sure CPU is clamped down and heatsink is properly secured. Plug in onboard video from motherboard to your monitor. Do not plug in anything else (keyboard, mouse, GPU, RAM, SATA drives, etc). Boot up, and POST should display a message on your monitor about 'no memory installed'

    There could be a slew of issues, so let's narrow it down.
    Do all your fans spin and LEDs light up?
    Does your MOBO have beep codes?
    Did you try a different monitor?
    Is the voltage setting on your MOBO at 115v (North America) or 230v (Europe)?
    If you manage to reach the UEFI/BIOS, check which SATA port your storage drive is plugged in to and try a diff SATA port.
    Look at the spec sheet for your motherboard. Are the CPU and RAM lights supposed to indicate an issue or a successful connection?

  4. I have tried barebones booting. With no RAM both the ram led and cpu led light up. These are meant to indicate an error so I'm leaning towards either the cpu or the motherboard.
    It's definitely not the graphics card or the monitors as I am using them right now.
    No motherboard speaker so I don't have beep codes to work with.

    Can't get to UEFI at all.
    Strange that I was able to boot linux fine for a few days and now I can't get it to post.

    Did you boot to Linux from a flash drive, hard drive, or disc? Just an idea, you could try again with Yumi installed to a flash drive https://www.pendrivelinux.com/yumi-multiboot-usb-creator/

    The scariest component to mess with is the CPU- but you may need to inspect it. AMD uses PGA (pins are on the processor) while Intel uses LGA (pins are on the motherboard), and if any of these pins are bent, you're screwed. Take a look at the processor pins, reseat in to its socket, apply new thermal paste, and put the heat sink back on.

    When you first started installing Windows, at what point did it crash?
    Did you change any settings in the UEFI/BIOS?
    If the MOBO came with a disc, try booting to that. On startup, mash the DEL key or whatever key is assigned by your motherboard

  6. Similar thing happened to me. My first boot is fine, and I went on installing Win 7, and because I couldn't get windows 7 to instantly work on Ryzen systems, after Win 7 installation, I tried to copy AMD Drivers to the OS installed HDD. When I put it back on, there's not post. The CPU led blink and then nothing. The fans and leds are on. Tried removing the RAM, cleared CMOS, GPU, reinstalled CPU, nothing works. The only thing I haven't try yet is to flash the BIOS. It seems like there's some way to flash the BIOS even when there's no post. I would be nice to know if your situation is getting better, and post the update here.

  7. I had the same problem with the MSI B350M motherboard, the assembly was correct and did not turn on, the technician simply switched the battery that was zero power, ready the computer called after the exchange!

  8. My previous answer is wrong- this is an ongoing issue with B350M motherboards and Ryzen processors.

    I actually saw the issue firsthand this weekend when installing a Ryzen 3 to an ASrock B350M motherboard. All the hardware was brand new from Newegg. The only things plugged in were Power Supply > Motherboard > Processor > CPU Fan and the system would not POST. Even without RAM, your motherboard will still communicate through beep codes or video display that you are missing memory. Fans and LEDs would spin up for about 15 seconds, then reboot.

    What is interesting is after hours of configuration testing- lots of reboots, different GPU, different display types (DVI and HDMI), unplugging CMOS for 5 minutes, clearing CMOS with jumper, booting with and without RAM, re-seating Ryzen and heatsink, crying out to the PC gods for an answer, I was able to boot successfully long enough to install Windows 10 and test a Steam game.

    HOWEVER, the issue is completely intermittent. No matter how many times I got it to work, it was only temporary and the system would randomly crash every single time. This motherboard had its beep codes disabled by default, so once I enabled them in the UEFI menu it would do 3 short beeps, pause, and 8 short beeps (https://ddr4motherboard.com/beepcodes/ASROCK-AB350M-PRO4). I am sending it back to Newegg for a replacement- I will do the exact same testing with a new motherboard to see if the issue is because of an unlucky defective board or because of a poorly made product. This issue is all over the internet, so my guess is the latter.

    Do you know if the technician replaced the CMOS battery?

    I solved my problem, which I also believe that will solve yours and others with the same problem, by taking the motherboard to msi service center, and let them flash the bios. The main problem with most of the boards as far as I searched from the internet are BIOS, and RAM. With BIOS as the main culprit. Back then we'll need a Ryzen 7 series cpu to be able to flash the BIOS if your motherboard haven't got the up to date BIOS installed, I don't know about now. If you receive your new mobo and still having the same problem, I would suggest you to bring it to a service center and let them update it for you.

  11. I updated the BIOS from v2.00 (out of box factory version) to v3.10, but this is an ASRock motherboard (http://www.asrock.com/mb/AMD/AB350M/#BIOS). I'm also using Ryzen 3, not 7. It did not solve the issue. I'm not sure if these manufacturers are using the same BIOS/UEFI images but the symptoms we are having are the same.

    Did MSI give you any service notes or paperwork? I'm interested to see exactly what they did.

    As far as I read it happens to all AM4 motherboard, regardless of the manufacturer. Mine is a MSI B350 PC MATE. What I meant was you need a Ryzen 7 to flash the BIOS, and then install your Ryzen 3 or 5 to make it work, that's if you got a Ryzen 7 at hand. But I might be wrong, so if there are other people who knows for sure, please do correct me.

    Well they don't give me anything, but they told me that what they did is only flashing the BIOS, and that was also my request when I took it to them. Because I'm very positive by reading people's complaints, that's the only thing that needed to be done. What I forgot to make sure was whether they used a Ryzen 7 or not when they flashed it. To make things simple and quick, if you got a ASROCK service center near you, just let them flash it for you. It only took me about thirty minutes of waiting.
