Question:

I have been experiencing random BSODs and mouse lagging in Windows 11 after switching from an Intel system to an AMD system. I also changed my GPU and added more RAM before the switch. I have tried many troubleshooting steps, including flashing the BIOS, reseating the RAM and GPU, running various tests and scans, and reinstalling Windows 11, but nothing has worked. I suspect that the problem is hardware-related, possibly with the CPU or RAM. What could be the cause of these issues and how can I fix them?

How to Solve BSODs and Mouse Lagging in Windows 11 After Switching to AMD System

If you have recently switched from an Intel system to an AMD system, and also changed your GPU and added more RAM, you may encounter some issues with your Windows 11 PC, such as random blue screens of death (BSODs) and mouse lagging or stuttering. These issues can be very frustrating and affect your productivity and gaming experience. In this article, we will explain the possible causes of these issues and how to fix them.

There are many factors that can cause BSODs and mouse lagging in Windows 11, especially after changing your hardware components. Some of the possible causes are:

• Incompatible or outdated drivers: Drivers are software that allow your hardware devices to communicate with your operating system. If your drivers are not compatible with your new hardware or Windows 11, or if they are outdated or corrupted, they can cause conflicts and errors that lead to BSODs and mouse lagging. This is especially true for your GPU and chipset drivers, which are essential for your graphics and system performance.
• Faulty or incompatible hardware: Sometimes, the hardware itself can be the source of the problem. If your new hardware is faulty or defective, or if it is not compatible with your motherboard or other components, it can cause instability and crashes that result in BSODs and mouse lagging. This is especially true for your CPU and RAM, which are crucial for your system performance and stability.
• Incorrect BIOS settings: BIOS is the firmware that controls the basic functions of your motherboard and hardware. If your BIOS settings are not correct or optimized for your new hardware or Windows 11, it can cause issues with your system booting and running. This can also lead to BSODs and mouse lagging. This is especially true if you have flashed your BIOS to make it compatible with your new CPU, or if you have enabled or disabled some features such as XMP, overclocking, or adaptive sync.
• Windows 11 bugs or glitches: Windows 11 is still a relatively new operating system, and it may have some bugs or glitches that affect its performance and compatibility with some hardware devices. Some of these bugs or glitches may cause BSODs and mouse lagging, especially after changing your hardware or updating your Windows 11. Microsoft is constantly releasing updates and patches to fix these issues, but sometimes they may introduce new ones.

How to Fix BSODs and Mouse Lagging in Windows 11

Depending on the cause of your BSODs and mouse lagging in Windows 11, there are different solutions that you can try. Here are some of the most common and effective ones:

• Update your drivers: The first and most important step is to update your drivers to the latest versions that are compatible with your new hardware and Windows 11. You can do this manually by visiting the official websites of your hardware manufacturers and downloading the drivers from there, or you can use a driver updater tool that can automatically scan your system and install the best drivers for you. You should pay special attention to your GPU and chipset drivers, as they are the most likely to cause BSODs and mouse lagging. You can also use the Device Manager to check for any missing, outdated, or faulty drivers and update or uninstall them accordingly.
• Check your hardware: The next step is to check your hardware for any faults or incompatibilities. You can do this by running some hardware diagnostic tools, such as the Windows Memory Diagnostic Tool, the Performance Monitor, or the System File Checker. These tools can help you identify and fix any errors or issues with your hardware devices, such as your CPU, RAM, GPU, or SSD. You can also use some third-party tools, such as CPU-Z, GPU-Z, or CrystalDiskInfo, to monitor your hardware performance and health. You should also check your hardware connections and make sure that everything is properly seated and plugged in. You may need to reseat your RAM and GPU, or change their slots, to ensure that they are working properly. You may also need to replace your hardware if it is faulty or incompatible with your system.
• Adjust your BIOS settings: The third step is to adjust your BIOS settings to make sure that they are correct and optimized for your new hardware and Windows 11. You can do this by entering your BIOS setup menu, usually by pressing a key such as F2, F10, or Delete, during the system startup. You should check your BIOS version and update it if necessary, to make sure that it supports your new CPU and other hardware devices. You should also check your BIOS features and settings, such as XMP, overclocking, adaptive sync, or power management, and enable or disable them according to your preferences and needs. You should also check your boot order and make sure that your Windows 11 drive is the first one. You may need to reset your BIOS settings to default if you are not sure what to change or if you encounter any problems.
• Update your Windows 11: The last step is to update your Windows 11 to the latest version that is available. You can do this by going to Settings > Windows Update and clicking on Check for updates. Windows 11 will automatically download and install any updates or patches that are available for your system. These updates or patches may fix some of the bugs or glitches that cause BSODs and mouse lagging, or improve the performance and compatibility of your system with your new hardware. You should also check for any optional updates or drivers that may be relevant for your system and install them if necessary.
