Question Normal for MSI Z97 Gaming 5 to flash 9C & A2 and cold boot to win10, boot time at 34.3sec on SSD?

I have read some topics about it, but want to double check.
While PC is booting, these codes flashes one by one on screen
(lower right corner) and on led which is on Motherboard.
But it doesn't stay on it , just short flash.
Cold Boot time from powering up -> MSI Dragon logo -> Windows 10
is 34.3 sec Last Bios Time on my Samsung 840 EVO 250GB SSD.
So is it OK (its doing some kind of checking) or it is sign that something wrong in system?
Sorry poor grammar!

Problem Fixed! I fix the issue by re-plugging the USb port for the Keyboard + Mouse into the correct USB 2.0 port. What dumb idiot i am, plugging my mouse and keyboard into the wrong USB port causing the 9C error delay flash from a few seconds to 15 - 20sec.

Now my boot time from power to desktop is 11 sec +
Admins, do mark this thread as closed or solved, sorry for the spam!

This user from tomshardware had the same problem as me and he solved it.

''Whenever i boot it the screen shows error codes at the bottom right corner including the 9C code hanging at around 15-20 sec followed with a A2 code hanging at 2 sec and it eventually boots to Windows. One thing that i've noticed is that when i disconnect all the devices that use USB the 9C code disappears but comes back once i connect something to a USB and boot the second time.''

Hi there,

Apologies, for the late reply.
Yes, apparently there were detection lags for certain chipsets @ that time.
One that I know of was SiliconPower USB 3 chipsets.
Once you plug-in, it took a long time to detect which affect the boot up.
But if you removed it and only plug in when in windows,
it was fine.
Thanks for the update.


Cheers.
