Question Pc won't boot after bios update

[blue_Fire]

Just updated the bios for the MSI z390 Pro Gaming Carbon to 7B17v1B. Now when I try to turn on my pc it will flash on for a split second then turn off.
PC specs:
Motherboard: MSI z390 pro gaming carbon
Cpu: 9900k
Gpu: zotac rtx 2080 amp!
Ram: Gskill Trident Z 3200mhz 32GB

Any recommendations on how to fix it?

What BIOS version were you on prior to the update? You could try and disconnect from the wall and then remove the CMOS battery for at least 30 minutes, before replacing. Make and model of your PSU and it's age?

Unfortunately not sure of my previous bios version. And I'm using the corsair hx750 platinum which have had for a little over a year. I'll try removing the CMOS battery

I've seen boards that behave such that, after a BIOS update and/or reset, the board will power down immediately after you turn it on. But after a second or two, it will power on by itself again.

Removing the CMOS battery unfortunately hasn't worked any other suggestions?
