BIOS Version - SOX5810J.86A.5561.2011.0516.2023
I had tried to upgrade to WIN 11 but the install failed and, thnking about it, that's when the troubles began, after I swapped out the ASUS (i9) motherboard and reverted back to the DX58. I thought that WIN 11 would give me the improved performance but the DX58 wouldn't cope with the UEFI(?) specification
