Now that we went over every potential culprit that might be responsible for this issue, let’s go over a list of fixes that other Windows 11 users have successfully used to fix these annoying occurrences where the PC randomly freezes before eventually crashing. Until then, you can make sure that you’re running with the latest BIOS update available for your motherboard.

Outdated BIOS or vBIOS version – BIOS-induced crashes and performance hiccups are to be expected until motherboard manufacturers begin to ship hardware running in the firmware that’s fully optimized for Windows 11.

The only option available as of now is to uninstall the software altogether. Unfortunately, there is no official or unofficial fix that will allow you to deal with this issue while keeping the software installed.

Sonic Studio 3 conflict – There is one particular tool from ASUS that is known to cause freezes when installed on Windows 11 (Sonic Studio 3).

To avoid this issue, you can either unplug the AC adapter or disable the ACPI Battery Control functionality using Device Manager.

Power Adapter bug – Certain laptop models (particularly ASUS and MSI models) seem to suffer from a Windows 11 bug where users start experiencing freezes and crashes as soon as the battery is fully charged.

The only workarounds for this bug are to switch the external display’s resolution to a 16:9 aspect ratio or disconnect the display entirely. As of now, there is no official fix from Microsoft.

Ultrawide bug – If you’re using an external ultrawide display, there’s a big chance you will experience the notorious bug where your screen freezes for a couple of seconds randomly.

To fix the issue in this case, you need to update your GPU driver fleet to the Windows 11 equivalents either by using Device Manager, WU, or the proprietary software from Nvidia or AMD.

Incompatible GPU drivers – Another reason why you might see this error is a scenario in which you recently upgraded to Windows 11 from an older Windows version and you’re still using the old GPU drivers that we’re migrated over.

If the freezing happens while your system tries to free up VRAM, you can fix the problem entirely by forcing your Windows 11 to work with a bigger paging file.

Insufficient VRAM – In case you are only working with 4 GB of RAM, issues of this kind can also be encountered whenever your system has to move temporary data to your virtual memory because RAM is already full.

In this case, you can resolve the freezes entirely by bringing your screen resolution down.

Unsustainable resolution – As it turns out, you can expect to face this type of issue on Windows 11 if you’re using a low-end GPU that’s not capable enough to handle the resolution you’re trying to enforce during resource-intensive tasks.
