Microsoft Windows Error Code 0x00000159: How to Fix It

Q: What causes Windows error code 0x00000159?

Error 0x00000159 is typically caused by faulty drivers (especially graphics or chipset drivers), corrupted system files, RAM issues, BIOS/UEFI problems, or conflicts with virtualization software that interfere with the IOMMU hardware component.

Q: Is error code 0x00000159 serious?

Yes, this is a critical system error that causes blue screen crashes. It indicates problems with hardware-level memory management and can lead to data loss if not addressed promptly. The system becomes unstable and may crash frequently.
