PC not POSTing or outputting display

[BrendanW098]

Hi, my specs are:

• Ryzen 5 3600 - stock speeds
• MSI B450M Mortar MAX
• 2x 8GB Corsair Vengeance RAM @ 3000MHz
• EVGA GTX 1070 FTW
• Corsair CX 450M PSU
• 1TB WD Blue
• 240GB WD M.2

I built this PC yesterday and all was working fine. It POSTed, I went into the BIOS to OC the RAM to 3000MHz. Installed windows 10 form USB onto the M.2 drive. Installed all necessary drivers and then installed CSGO and ArmA 3 from Steam. All was working fine yesterday and the games were running smoothly and problem free.

I powered up the system today, windows started up, I signed in and all was going well. After about 2-3 minutes, the PC shut down and the CPU EZ Debug LED was lit on the motherboard. Since then, the system has not started up, no display is being outputted from the GPU. The CPU EZ Debug LED lights up when turning the system on but does not stay illuminated.

 

So far I have done the following to try and fix the solution:

• Reseated the CPU, ensuring there are no bent pins
• Reseated the GPU
• Reseated RAM
• Used a different PSU to power the system, incase of a faulty CPU power cable
• Tried a basic configuration with 1 stick of RAM (used both one at a time), CPU and GPU
• Unplugged both M.2 and HDD incase of driver errors
• Flashed the BIOS to the latest stable version from MSI Mortar MAX support page

After this, the issue is still persistent. When powering on the system, all lights and fans spin that should but there is still no display output - there is no output to even get into the BIOS or access boot menu etc. The CPU EZ Debug light lights up when the system is powered on but this then goes off.

 

Any help on this would be greatly appreciated.

Have you reset the CMOS?

Do you have multiple monitors? Check the display cable, try turning off and on the monitor, try a different port on the gpu, try a different gpu if you have one, try using that gpu in a different system, take out the cmos battery and have the mobo reset, and tell me what happens when you do anything I listed.

It actually sounds like the machine is POSTing fine, have you verified the monitor is working? It possibly switched to another Input, the cable might be bad or even the monitor might have died.

He flashed the BIOS, this performs a CMOS reset.

Only if the BIOS update is successful, and given that the built in BIOS updating feature is limited in it's ability to notify users of what's happening it's possible it didn't. CMOS reset never hurts to try.

Its possible that he saved the settings as a profile tho. Not saying for sure that's the case but its easy to do and fixes a lot of things especially if the gpu isn't sending an output during boot.

I haven't reset the CMOS itself, but I did flash the BIOS which should've reset the CMOS as Master Disaster said. I will try a CMOS reset on it's own though.

 

I only have the one monitor and there are no onboard graphics so the only output can be from the GPU.

I have tried plugging it into a known working TV and there is still no output. Have also tried a different HDMI cable.

This is the very reason why I personally would never use BIOS Flashback. You have no idea what its doing at any given time.

I have just reset the CMOS by removing the battery for 3 minutes, still no joy. 

The system seems to boot, no lights are lit up on the EZ Debug, all fans spinning etc. but there is still no output to the display.

GPU might have failed. Interestingly when I bought my Vega 64 it was DOA and the system also froze on the CPU LED, not the GPU one. I RMAed it, got a replacement and it worked great from then on.

Do you have another GPU you can try? Back when I bought my 290x I had it running for about 8-10 hours before it shit out on me and needed to be replaced, so it's possible yours is just defective even after running for a short while.

That's weird, I will try and find another GPU tomorrow to see if it is that. I would be odd though since the GPU was working absolutely fine yesterday

I don't no, I shall try to find another tomorrow to test if it is this.

I cleared the CMOS and once that was done the GOU outputted the display to press F1 to initiate setup or F2 to use default values, so I'm happy there's nothing wrong with the GPU.

I went into the BIOS and left without changing anything and the issue is still persisting and I also cannot get back to this stage by resetting the CMOS again, as even when I reset the CMOS no display is being shown.

I believe there may be an issue with the RAM being OC'd to 3000MHz but I can't get back into the BIOS to change this.

2 things.

 

1) That probably means the BIOS update failed so once you get back into BIOS check the version number. Chances are updating the BIOS will clear this issue up.

2) How exactly are you resetting the CMOS?

1) Ahh ok, I will try and get back in but atm its not outputting any display again.

2) I'm resetting the CMOS by removing the battery for ~10 mins as the motherboard didn't come with the jumper cap
