MSI Gaming 5 - Getting an A2 and 9C Error...

[LoneSurvivor]

After a night of gaming, I awoken earlier on today to find out that my computer is acting quite odd. When I try to boot it up, it will go through its usual dragon logo page while it loads, but would for about a second flash 9C and A2 on the lower right corner. My mobo shows this at the same time as well, in the temperature reading. Eventually the monitor will flash gray and dark twice and it'll go back to the dragon logo, loading once more. Pretty much goes like a never ending loop.

I didn't try anything too over the top such as messing around with CMOS, instead I did the following:
-Checked for any loose cables inside the PC
-Restarted the PC
-Check for any used ports that might have something that triggers these errors.
-Removed every external cable except the VGA and PSU cables and restarted the PC.
-Returned my BIOS settings to default (Not by CMOS, just through the moba setup page.)

I tried searching online for help, but to no avail. Most of them lacked the clear and simple message for a beginner geek like me, and the ones that did failed to help me.

But hopefully my dear friends at tomshardware can help! 😀

What do 9C and A2 mean?

Post your build.

I'm not exactly sure on what they are but they are errors that happen during the process of booting up your computer.

My Build:
-Motherboard: MSI GAMING 5
-CPU: i5 4690k
-GPU: Intel HD 4600
-PSU: CXM 750M

My bad, accidentally triple posted.

I bet they are in your motherboard manual.

9C is a USB error and A2 is an IDE error. Here's a couple of things to check:

Your system could be searching for a USB boot device Go into your BIOS and ensure that the boot priority is set for your OS drive.

Your system could be having issues with one of your connected USB devices. Try updating your chipset and USB drivers, as well as any appropriate drivers for attached devices.

You could also try connecting your devices to different USB ports.

Sorry for very late reply, but I can't find through the table of contents the list of errors at all. By OS drive, do you mean the hard drive that has the OS installed? Also, my bootup device priority shows a UFEI hard disk and just hard disk, which one should come first? I have also tried disconnecting everything except VGA and power cable (so I can see) and fails. I don't think that removing the VGA cable would change that, and also think that this pretty much rules out trying to connect devices to other ports. I'll try to update the drivers by downloading and inserting it from a USB, but I believe that I most likely updated most of them at least a month ago.

It is an old post, but I also had the C9 error code on my z87 g43 due to an USB stick plugged in upon starting the system. Similar experiences of other users are described here: https://forum-en.msi.com/index.php?topic=252491.0
I pick i7Baby´s answer as a solution.
