I experienced a "new" issue, for me. The standoffs from the prior ATX board were sitting directly under the solder points for the memory. Reboot loop. Don't ask me how long it took me to work that out. Debugging had taken me to the conclusion that the board was warped since it didn't boot when I put in the screws in the upper left side of board.]]> Thu, 27 Feb 2020 06:29:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=9750&PID=73174&title=asrock-b450m-pro4-boot-problems#73174 <![CDATA[ASROCK B450M Pro4 - Boot Problems : uda-h wrote:Hello all,that...]]> https://forum.asrock.com/forum_posts.asp?TID=9750&PID=63482&title=asrock-b450m-pro4-boot-problems#63482 Author: xhue

The cause is your OLD PSU which has only 2.5A 5Vsb.

I spent quite some time discovering this issue.
Something like 5 days :-)



How much power consumption do you have on the 5V rail? ]]> Sat, 01 Jun 2019 20:20:00 +0000 https://forum.asrock.com/forum_posts.asp?TID=9750&PID=63482&title=asrock-b450m-pro4-boot-problems#63482 <![CDATA[ASROCK B450M Pro4 - Boot Problems : Hello all,that problem is related...]]> https://forum.asrock.com/forum_posts.asp?TID=9750&PID=63481&title=asrock-b450m-pro4-boot-problems#63481 Author: uda-h

I had a similar issue with my B450M Pro4. 

However disabling fast boot in Windows itself and updating to the newest BIOS seems to have fixed it. 
It seems that the manual XMP Settings in the BIOS couldn't be loaded after shutting down the system because of Windows fast boot which prevents certain parts of the system to completely shut down after it has been turned off. 

Which actually brought my RAM down to 2100MHz instead of the normal 3000MHz. 

Now after disabling Windows fast boot in the energy settings in Windows and updating to the newest BIOS seems to have fixed the issue for me.

By Odin! I swear ASRock's A/AB series must be the most RMA'd ones ever... Big smile

P.S. I'm glad that all is OK for OP now. Hug

After contacting ASRock support, they had a few other recommended troubleshooting steps.

The primary recommendation was to remove the board from the case, and to only attach the CPU/CPU Cooler, 1 RAM module, GPU, and boot device. 

The result of this test was the same as with the board fully connected in the case - it still wouldn't boot after a shutdown.

I ended up replacing the board, and everything functioned normally.

Thanks for the helpful ideas!
