MPG Z590 Gaming Force Bug?

[ander1239154d02d6]

Noticed something weird the other day. My Wife’s build refused to go into the BIOS whenever I would hit the Delete Key. The PC would just hang during POST on a black screen. The debug LED would be either A1 or B4. I eventually got into the BIOS by just hitting the delete key once instead of my normal spamming of it. Anyone else have this issue? I was only one BIOS revision behind so I updated it. However the PC appears fine. Just whenever I need to get into the BIOS it can be a pain.

Hi
It may be a bug, though such can be triggered by many different factors and aren't exactly easy to replicate. Sometimes even video cable can be the root cause of all kinds of issues.
I'd suggest you contact MSI about this, but unless they have exact hardware and peripherals on hand, it may not be possible to replicate for them. >>How to contact MSI.<<

Try to press Ctrl+Alt+Del and see if it gets display after reboot.
If your monitor has any power related setting in OSD menu, try to set it to power standby mode, for example, MSI monitor has Power Button Standby in OSD menu > Setting.
