No, it’s not a Windows system malfunction, but a hardware issue that is preventing the OS from loading properly, and that’s why the boot/reboot sequence cannot be completed. Simply put, the Windows OS cannot be initiated. The motherboard 99 code is not even an actual error. It shows what stage it’s currently running and in this case, we are discussing problems within Super IO Initialization. In a few words, the debug code 99 is talking about an issue related to the boot process and more particularly with the master hard disk. Of course, the motherboard can cause the issue, but it might be something with the BIOS setup too. In this article we will try to find the proper fix for PC error code 99 and kidiconnect error code 99, so keep reading.

How can I fix the motherboard error code 99?

1. Set the SATA mode into AHCI

If you can go to BIOS, you should start the troubleshooting process by ensuring that the SATA mode is set into AHCI instead of IDE. Moreover, the boot order should follow the UEFI protocol by default.

2. Verify the Time and Date from BIOS

In order to fix the motherboard error code 99, you can also verify the Time and Date from BIOS. While your PC boots, keep pressing Del or certain F key to enter BIOS. Usually there will be a message saying to press a certain key (F1, F2, F10) to enter SETUP. SPONSORED If you can’t find this key, check your motherboard manual to see which key is used to enter BIOS.  Once you get to the Main menu, you have to locate the Time and Date section. Navigate to the section by using the arrows keys, and verify the time and date. Select Save and Exit to exit.

3. Reset or update CMOS

You can even choose to reset or update CMOS as this can easily fix the error code 99. Do note that depending on each manufacturer the BIOS options might differ. Updating BIOS without booting into Windows is possible only for newer motherboards while making a reset can be done by accessing factory settings. You can also reset the motherboard by removing and re-applying the BIOS battery, though this is a complex process which will imply in disassembling your PC, so be careful and try not to mess things up even worse. Note: Don’t be afraid to ask for more experienced help if you are not a tech expert.

4. Other troubleshooting solutions to apply

Verify the supply cables and make sure that HDD SATA is properly connected. Check all the other connections from your motherboard and make sure that everything is working by the book. Go to BIOS and check if the HDD is detected or not; if the HDD isn’t shown you might have a faulty HDD. Disconnect the peripherals before initiating a new reboot – just remove any external devices attached to your Windows device. Try to boot up only the motherboard – unplug everything else, besides your keyboard. Also, remove RAM and anything else that might not be required for an initial boot (including audio and USB from the motherboard). Please note that sound cards and NIC cards should be also disconnected. If you built your own PC, make sure that everything is connected as it should and that you didn’t forget anything else. Again, don’t hesitate and ask for an experienced opinion, depending on your own system configuration.

As already outlined, the debug code 99 describes Super IO Initialization issues. So, the fixes should focus on this particular field.
