Cybertron PC installed A4-5300 FM2 CPU onto a FM2+ motherboard and now can't install A10-8850B FM2+ CPU because of RADEON HD7840D vs RADEON R7 conflicts. 

Error 182 – Radeon Software Install Detected AMD Graphics Hardware in Your System Configuration That Is Not Supported With This Software Installation

The computer screen goes black when with the A10-8850B CPU installed but works with the A4-5300 reinstalled. DDU was used to delete A4/HD files but can't install A10/R7 with A4 CPU installed. win10-radeon-software-adrenalin-2020-edition-20.4.2-may25 is creating the conflict

Thanks

That is for the 5300... https://www.amd.com/en/support/apu/amd-series-processors/amd-business-class-dual-core-a4-series-apu-... 

And

That is for the 8850... https://www.amd.com/en/support/apu/amd-pro-series-processors/amd-pro-series-a10-apu-for-desktops/6th... 

So... The updated display driver will not work properly with the 5300.

According to MSI Support for your Motherboard's CPU SUPPORT LIST, the A10-8850B is not listed as being compatible. Which is why it won't boot up since there is no BIOS version that recognizes that specific Processor: Support For A55M-E33 | Motherboard - The world leader in motherboard design | MSI Global 

These are the only A10 Processors supported by your Motherboard:

Thanks, this is my first crash course on motherboards not knowing there are many for FM2+ sockets thinking MSI was not up to date. I am maxing out the motherboard to last longer after installing 32gb RAM sticks and ordered A10-7850K
