一些使用MSI(MSI)主板的PC 用户遇到的问题是，当他们启动或重新启动Windows设备时，错误代码 99(error code 99)出现在黑屏的右下角。在这篇文章中，我们将找出潜在的原因，并为问题提供最合适的解决方案。
以下是潜在的罪魁祸首：
- 损坏的内核临时数据。
- BIOS / UEFI 不一致。
- 电源不足。
- USB 端口的 I/O 问题。
- 硬件问题。
主板错误代码 99
如果您遇到此问题，您可以尝试下面我们推荐的解决方案，看看是否有助于解决问题。
- 在 BIOS 中验证时间和日期
- 将磁盘控制器(Disk Controller)模式更改为 AHCI
- 移除(Remove)外围设备（如果适用）
- 清除 CMOS 电池
- 重置 BIOS
- (Connect)PS/2端口连接鼠标和/或键盘
- 更换主板。
让我们看一下关于列出的每个解决方案所涉及的过程的描述。
1]在BIOS中验证时间和日期
- 启动进入 BIOS(Boot into BIOS)。如果您无法启动进入 BIOS(unable to boot into BIOS) ，请遵循这些建议。
- 在主菜单(Main menu)中，使用箭头键导航到时间和日期(Time and Date )部分。
- 到达那里后，请确认时间和日期。
- 选择保存并退出(Save and Exit) 以退出。
现在尝试启动计算机，看看是否仍然出现错误。如果是这样，请尝试下一个解决方案。
2]将磁盘控制器模式(Disk Controller)更改(Change)为AHCI
当HDD控制器模式设置为IDE或RAID并且系统缺少适当的驱动程序时，系统可能会遇到错误。为了解决此问题，必须将磁盘控制器更换为AHCI。为此，您必须访问BIOS并按照正确的指南进行所需的更改。您可以在购买时提供的主板说明手册中找到正确的指南，或在互联网上查看。
注意(Note)：在将模式更改为AHCI之前，请在(AHCI)提升(elevated command prompt)的命令提示符下运行以下命令并重新启动计算机：
bcdedit /set {current} safeboot minimal (ALT: bcdedit /set safeboot minimal)
将模式设置为AHCI后，在提升的(AHCI)CMD提示符下运行以下命令并再次重新启动计算机。
bcdedit /deletevalue {current} safeboot (ALT: bcdedit /deletevalue safeboot)
如果问题仍然存在，请尝试下一个解决方案。
3]删除(Remove)外围设备（如果适用）
这可能是因为PSU（电源单元(Power Source Unit)）不足，无法为当前连接到 PC 的每个组件提供足够的电力。在这种情况下，如果您不想将PSU升级到容量更大的新设备，您唯一的选择是断开所有外围设备，如无线键盘、硬盘驱动器、打印机、USB集线器等。
4]清除CMOS电池
您可能需要硬件技术人员的服务。
- 关闭所有连接到计算机的外围设备。
- 从交流电源断开电源线。
- 卸下电脑盖。
- 找到板上的电池。电池可以放在水平或垂直的电池座中，也可以通过电线连接到板载接头。
如果电池在支架中，请注意电池上 + 和 - 的方向。使用中号一字螺丝刀，轻轻地将电池从其连接器中撬出。
如果电池通过电线连接到板载接头，请从板载接头断开电线。
- 等待一(Wait one)小时，然后重新连接电池。
- 重新盖上电脑盖。
- 重新插入计算机和所有设备。
问题还没有解决？尝试下一个解决方案。
5]重置BIOS
此解决方案要求您将 BIOS 设置重置为其默认值，看看是否有帮助。
6]通过PS/2端口连接(Connect)鼠标和/或键盘
如果您使用仍然有PS/2MSI主板，您可能会遇到此MOBO错误，因为您可能是由通过USB连接的外围设备引起的 I/O 问题。在这种情况下，您可以断开USB鼠标和键盘，并通过旧版PS/2端口插入较旧的外围设备。
7]更换MOBO
在这一点上，您可能会遇到短路，最终会弄乱您的内部结构。因此，如果设备仍在保修期内，您可以将主板或 PC 本身带入更换。
如果您的保修期已过，并且您的主板与您的CPU、GPU和RAM兼容，您可以更换有故障的MOBO并查看您的计算机是否可以正常启动。
希望这可以帮助！
Fix Motherboard error code 99 on Windows computers
Some PC users using MSI motherboards are exрeriencing the issue whereby when they boot or reboot their Windоws device, the error code 99 appears in the bottom-right corner of a black screen. In this post, we will identify the potential causes as well as provide the most suitable solutions to the issue.
Below are the potential culprits:
- Corrupted Kernel Temp Data.
- BIOS / UEFI Inconsistency.
- Insufficient PSU.
- I/O issue with USB ports.
- Hardware issue.
Motherboard error code 99
If you’re faced with this issue, you can try our recommended solutions below and see if that helps to resolve the issue.
- Verify Time and Date in BIOS
- Change the Disk Controller mode to AHCI
- Remove external peripherals (if applicable)
- Clear the CMOS battery
- Reset BIOS
- Connect mouse and/or keyboard via PS/2 ports
- Replace MOBO.
Let’s take a look at the description of the process involved concerning each of the listed solutions.
1] Verify Time and Date in BIOS
- Boot into BIOS. Follow these suggestions, if you are unable to boot into BIOS.
- At the Main menu, using the arrows keys, navigate to the Time and Date section.
- Once you get there, verify the time and date.
- Select Save and Exit to exit.
Now try booting your computer and see if you still get the error. If so, try the next solution.
2] Change the Disk Controller mode to AHCI
When the HDD controller mode is set to IDE or RAID and the system lacks appropriate drivers, the system might encounter the error. In order to fix the problem, the disk controller must be interchanged to AHCI. For that, you have to access the BIOS and make the required changes by following proper guidelines. You can find the proper guidelines in the instruction manual of the motherboard supplied at the time of buying it or check on the internet.
Note: Before you change the mode to AHCI, run the command below in an elevated command prompt and restart your computer:
bcdedit /set {current} safeboot minimal (ALT: bcdedit /set safeboot minimal)
After you have set the mode to AHCI, run the command below in elevated CMD prompt and restart the computer once again.
bcdedit /deletevalue {current} safeboot (ALT: bcdedit /deletevalue safeboot)
If the issue persists, try the next solution.
3] Remove external peripherals (if applicable)
This might because of an insufficient PSU (Power Source Unit) that’s unable to supply enough power for every component that’s currently connected to your PC. In which case, if you don’t want to upgrade your PSU to a new unit with a bigger capacity, your only option is to disconnect all external peripherals like wireless keyboards, hard drives, printers, USB hubs, etc.
4] Clear the CMOS battery
You may require the services of a hardware technician.
- Turn off all peripheral devices connected to the computer.
- Disconnect the power cord from the AC power source.
- Remove the computer cover.
- Find the battery on the board. The battery may be in a horizontal or vertical battery holder, or connected to an onboard header with a wire.
If the battery is in a holder, note the orientation of the + and – on the battery. With a medium flat-blade screwdriver, gently pry the battery-free from its connector.
If the battery is connected to an onboard header with a wire, disconnect the wire from the onboard header.
- Wait one hour, then reconnect the battery.
- Put the computer cover back on.
- Plug the computer and all devices back in.
The issue still unresolved? Try the next solution.
5] Reset BIOS
This solution requires you to reset the BIOS setting to its default values and see if that helps.
6] Connect mouse and/or keyboard via PS/2 ports
You may encounter this MOBO error, if you’re using an older MSI motherboard that still has PS/2 slots because you might be an I/O issue caused by peripherals connected via USB. In this case, you can disconnect the USB mouse and keyboard and plug in older peripherals via the legacy PS/2 port.
7] Replace MOBO
At this point, you might be up against a short circuit that ended up messing up with your internals. So, if the device is still under warranty, you can take the motherboard or the PC itself in for replacement.
In case your warranty has expired and you have a different motherboard that’s compatible with your CPU, GPU, and RAM, you can swap out the faulty MOBO and see if your computer boots up without issues.
Hope this helps!
