im having issue whith my system during restart when the wireless keyboard receiver is plugged in. my system boots just fine from shut down even if the receiver is plugged in and it shows a couple of error codes (9c, d7 and a2)but it still proceeds to windows without a problem.
it also proceeds to normal boot up when I plugged in a different keyboard or mouse even if the wireless receiver is plugged in during boot up.

this only happens during reboot such as after installing an update. it 'll show the same codes however I get stuck in A2.

I already checked all my drives and their connectors and they are all recognized just fine in the bios and the system.

my motherboard is an MSI z97s SLI krait edition and my keyboard is Logitech k400r.

Thanks in advance!
