0xc000021a Windows 11 crash / boots to BIOS

Dave Burris

I have two Beelink SER5 Max PCs running Windows 11 Pro giving the same error randomly: Your device ran into a problem and needs to restart. 0xc000021a. When it reboots, it boots to the BIOS screen. Power cycling it or disconnecting the power cable seems to allow it to boot again into Windows 11, but it will eventually crash again. The PC fans seem to get loud at times indicating a possible thermal issue. All Windows updates are applied. Are there any known hardware or BIOS issues with these units?

Model: SER5 MAX-L-32500EJ0W64PRO-DPXA
Serial Number: B68005HG21665

Hello Dave,

Sorry for the trouble.

Please repeatedly press delete key as soon as you turn on the PC, go to BIOS. Please send us a picture of the Main page, we will check if you need to update the BIOS.

Please change another power supply.

It is recommended that you can go to Microsoft official website to download the corresponding lastest win11 PRO system file to install, this is the tutorial: https://url.bee-link.cn/74zu

Please remember to backup the data.

Have a nice day~
