Even, you can face this issue when you are working with your PC as well. Due to the IO initialization interface error, the running programs can crash automatically. Faulty Asus motherboard and an incorrect BIOS time with outdated CMOS are also responsible for this critical error.
Besides this, the wrong SATA cable mode and PCI slot with BIOS defectivity issues degrade the performance of the Asus motherboard quite often. However, we are going to explain the processes to get rid of them and for the severe issue, it is important to connect with professionals.
Resolve Asus Motherboard Error Code 99 with Easy Steps
Some of the solutions will help you to overcome the Asus motherboard issues. Moreover, those fixes are very important to handle the IO initialization error effectively. So, follow the steps below and get hassle-free solutions to fix the motherboard problem.
Fix 1: Verify the BIOS Date and Time
First, check whether all the cables and components are set up properly or not. Incorrect settings of system date and time are the main culprits for creating the motherboard issue.
So, you might check whether the data shown in the BIOS screen are correct or not. Modify the time and date fields respectively with the current date and time by following the steps sequentially.
- First, right-click on the Taskbar and select ‘Start the Task Manager’ from the pop-up menu.
- After that, click on the Startup tab from the Task Manager window. If you can’t see the date and time, then click on the More Details option.
- In case of wrong time, you might open the CMOS setup and locate the Date and Time from the Setup menu.
- Now, navigate the arrow keys and adjust an appropriate date and time respectively.
- Then, click on the Save button and exit from the window.
- At last, reboot the system and resolve the error code 99 easily.
Fix 2: Upgrade the BIOS
Older version of BIOS is another problem that triggers the Asus Motherboard Error Code 99. Moreover, the device fails to perform correctly if you use the outdated BIOS. So, perform the below tasks and improve the BIOS settings.
- Open the System Information window and now check the Asus system model number.
- Now, verify the BIOS version number and open the BIOS manufacturer’s website.
- Next, look for the BIOS update file and verify twice whether the latest file CMOS BIOS file is newer than the BIOS version.
- After that, download the update file and then install it correctly.
- Finally, try to restart the PC and check whether the Windows OS initialization issue got fixed or not.
Fix 3: Reset the CMOS
If the CMOS settings error occurs, then you need to reset it at the earliest. The CMOS jumper is very useful and the quickest way to perform it.
- Disconnect all the cable and wires attached with your Asus system and turn off the PC properly.
- Now, open the motherboard from the system and locate the CMOS jumper.
- Next, handle all the three pins of jumper very gently. Set the jumper from 1-2 position to 2-3 positions.
- After cleaning the CMOS slot, wait for 7-9 minutes and reset it again to 1-2 position.
- Finally, turn on the Asus device and perform the reset operation in the opened BIOS screen.
The above method is easier to perform but it is very difficult to complete if you are not a tech-savvy person. So, the best way is to consult with an expert before starting this program.
Fix 4: Disconnect the HDD
If the hard disk drive setup error occurs, then disconnect the HDD along with all the cables and wires attached with it. Then, detach all the external drives that are responsible for the motherboard 99 error.
- Remove the battery from the Asus device and separate the screws that are used to set the HDD into a cabinet.
- Now, slide the Hard Disk Drive carefully and then disconnect it.
- After that, disconnect all the cables and wires connected to the hard disk drive.
- Wait for a while and reset them properly and verify whether the motherboard issue got fixed or not.
Fix 5: Install a new Motherboard
If the motherboard itself creates the problem to access the PC, then you need to replace the motherboard. Install a new motherboard successfully with the following steps.
- Verify the motherboard compatibility with your Asus laptop and then remove all the cables, wires connected to the CPU cabinet.
- Now, locate the CPU cooler from the CPU cabinet and separate the CPU socket cover gently without damaging the pins attached to it.
- Then, install a new motherboard and set the socket cover again in a proper place.
- After that, place the CPU cooler gently in it’s slot and plug-in all the cables and wires tightly.
- Next, close the CPU cabinet and switch on the device along with the processor unit.
- Finally, start the Asus system and verify whether the system is working properly or not.
Here, we have discussed the various troubleshooting steps that are quite effective to overcome the motherboard issues. Moreover, we have tried to define the significant reasons behind this annoying issue.
Besides the above solutions, you can change the configure the SATA cables and then reinstall the OS to fix the faulty motherboard issue. Without technical support, it is tricky to perform resolve the critical PCI slot issue and damaged MBR with ease. So, hurry up for immediate help.
