A320M Pro 4 no post after reboot

   Hi,
Im having problems with my ASRock A320M Pro4, 

In general the system works fine, however frequently on reboot from Windows the system sits with a blank screen and no post.

Whilst up it is fine and stable, however on a windows update restart etc it will just sit on blank screen, monitor is not powered up so im assuming the graphics card is not running.

There are no motherboard beeps and Windows thinks it has shutdown the system as far as i can tell.

Im running the latest BIOS and have tried a CMOS reset but it still happens.

Anyone have any suggestions? 

im running :

Windows 10 Creators
ASRock A320 Pro4
Ryzen 3 2200
8GB Crucial DDR4 2400
1050 GTX Graphics Card

	mjinglis, please post your BIOS/UEFI version. I assume you do not have a speaker to listen for beeps. Please get one and tell us what the beep code is. Does all 8GB of your memory show in W10 Task manager? Enjoy, John.

	Running BIOS 4.50 I do have a speaker and there are no beeps whatsoever (i know the speaker works as when i go into the BIOS when it works, i get one beep). Windows 10 is showing all 8GB memory in the task manager and system properties.

	mjinglis, I suggest you give Beta BIOS/UEFI 4.63 a go. Enjoy, John.

	Well it doesn't fail to post any more on reboot. Now the whole system freezes up randomly after a period of hours. Only thing that has changed is the BIOS... Its made it worse!

	Sorry you have a new problem now, mjinglis. It does not have to be a Beta BIOS/UEFI problem, but you can always go back. I assume you were running for much longer than it takes to hang now? If your memory is two sticks, please remove one and see how it goes. If it continues to hang, please try the other. Please let us hear the results. Enjoy, John.

	Thanks for your help, No it runs for less time, I have tried switching out the ram altogether with known good ram and it still has this behaviour. I've tried a different operating system, a different power supply, a different graphics card and a different boot drive, none of them fixed it. Given it will run for 24 hours on a benchmarking test, it doesn't seem like a hardware issue, but likewise since it happens on a different operating system it doesn't seem like software, so i have come down to motherboard or BIOS

	mjinglis, sounds like you have done a good testing job. Please open an ASRock ticket and see what they think. I had a bad X370 MB (required RMA) that hung when memory was in slot A1 or A2. Good luck and enjoy, John.

	Given up i've tried everything, One thing is for sure 4.6 is awful firmware, system crashes all the time, i've gone back to 4.50 and raised a support ticket, something is fundamentally wrong. Less than impressed with ASRock so far

	Could it be a powerplan issue? I know it cause problems for me ( and still does) and wifi is another suspect area. try disabling in BIOS
