I seem to be having this issue where when I turn on my computer, I get a boot error code of 9C followed by an A2. I have to remove my network cable, wait for it to POST then login to Windows before I can get back to normal and plug in my network cable. Otherwise, the board will not POST.

A quick check online indicates that this code 9C appears to be a USB boot issue, which is strange as I have no USB boot drives in my system. I have my SSD set as the first priority for the boot order, so it should be going to my SSD right away when booting. This also appears to be widespread in MSI motherboard line-up (this 9C error, judging by the fact that different models of MSI boards seem to be having this issue).

Does anyone have any solutions? I've moved my SSD up to the top of the boot order chain, but it does not seem to be solving the problem, nor does clearing out the CMOS.

I might try testing out with a PS2 keyboard if that helps.
