Fixing INVALID ACPI TABLE (0X000045) Stop Code on Windows 10 & 11 Step by Step

The INVALID ACPI TABLE (0x00000045) stop code, also known as a Blue Screen of Death (BSOD), is an error that can occur in Windows 10 and 11 when the system encounters issues with the Advanced Configuration and Power Interface (ACPI) tables. This error typically appears during startup or while using your computer, causing it to crash unexpectedly. While frustrating, this issue is often fixable with the right steps.

In this guide, well explain what causes the INVALID ACPI TABLE error, how to identify it, and provide step-by-step solutions to resolve it effectively. Whether you’re a beginner or an intermediate user, these methods should help stabilize your system.

What Causes the INVALID ACPI TABLE (0x00000045) Error?

The INVALID ACPI TABLE error occurs when Windows detects corruption or inconsistencies in the ACPI tables, which are used to manage hardware interactions like power states, sleep modes, and device communication. Common causes include:

  • Outdated or corrupted system files. Critical Windows components may become damaged due to improper shutdowns, driver conflicts, or software updates.
  • Faulty hardware drivers. Drivers for motherboard chipsets, graphics cards, or other hardware may not be properly installed or are incompatible with your system.
  • Corrupted firmware (BIOS/UEFI). Outdated or buggy BIOS/UEFI settings can trigger ACPI-related errors.
  • Overclocking or hardware issues. If youve recently overclocked your CPU, RAM, or other components, it may cause instability in the systems power management.
  • Malware or disk errors. In rare cases, malware or bad sectors on your storage drive can interfere with system stability.

The error often appears with a blue screen displaying:

*** STOP: 0x00000045 (0x0000000000000001, 0xFFFFFA80003C1D060, 0xFFFFF80002B7A9E0, 0xFFFFF80002B7A450)

How to Fix INVALID ACPI TABLE (0X00000045) in Windows 10 & 11

Below are the most effective methods to resolve this issue. Start with the simplest steps and proceed if needed.

—

###

Method 1: Run System File Checker (SFC) and DISM

Corrupted system files can trigger BSOD errors. Running System File Checker (SFC) and Deployment Image Servicing and Management (DISM) can repair missing or damaged files.

  • Open Command Prompt as Administrator:
    • Press Win + X, then select Terminal (Admin) or Command Prompt (Admin).
  • Run SFC Scan: 
    sfc /scannow

    Wait for the scan to complete. Restart your PC afterward.

  • Run DISM Repair: 
    DISM /Online /Cleanup-Image /RestoreHealth

    This may take several minutes. Once done, restart your computer.

After both scans, check if the error persists.

Method 2: Update or Reinstall Problematic Drivers

Outdated or conflicting drivers (especially chipset, graphics, or storage drivers) are a common cause. Heres how to update them:

  • Open Device Manager:
    Press Win + X, then select Device Manager.
  • Check for Problematic Drivers:
    Look under categories like:

    • System devices
    • Display adapters
    • Storage controllers
    • Universal Serial Bus controllers

    If you see a device with a yellow exclamation mark, right-click it and select Update driver.

  • Use Windows Update:
    Go to Windows Update (Settings > Update & Security) and install all pending updates.
  • Reinstall Drivers Manually:
    If updating doesnt work, download the latest drivers from the manufacturers website (e.g., Intel, NVIDIA, AMD).

Method 3: Check for BIOS/UEFI Updates

An outdated or buggy BIOS can cause ACPI-related crashes. Update it if your motherboard manufacturer provides a newer version.

  • Identify Your Motherboard Model:
    Open Task Manager (Ctrl+Shift+Esc), go to the Performance tab, and note the Motherboard details.
  • Download the Latest BIOS:
    Visit your motherboard manufacturers support page (e.g., ASUS, Gigabyte, MSI) and download the latest stable BIOS/UEFI version.
  • Update BIOS:
    Follow the manufacturers instructions carefully. This usually involves:

    • Creating a bootable USB drive with the BIOS file.
    • Entering BIOS setup (usually by pressing Del, F2, or F12 during startup).
    • Selecting the Update BIOS option and choosing the downloaded file.

Warning: Updating BIOS incorrectly can brick your motherboard. Ensure you have a backup power supply and follow instructions precisely.

Method 4: Disable Fast Startup (Hybrid Sleep)

Fast Startup, while convenient, can sometimes cause ACPI conflicts. Disabling it may resolve the issue:

  • Open Power Options:
    Press Win + R, type powercfg.cpl, and press Enter.
  • Click “Choose what the power buttons do”:
    Click Change settings that are currently unavailable.
  • Uncheck “Turn on fast startup (recommended)”:
    Click Save changes, then restart your PC.

Method 5: Run CHKDSK to Check for Disk Errors

Bad sectors or disk corruption can trigger BSODs. Use CHKDSK to scan and repair your drive:

  • Open Command Prompt as Admin:
    Press Win + X, then select Terminal (Admin).
  • Run CHKDSK:
    Type the following command and press Enter:

    chkdsk C: /f /r

    Replace C: with your system drive letter if needed. If the drive is in use, youll be prompted to schedule it for the next reboot.

  • Restart Your PC:
    The scan will run automatically during startup.

Method 6: Test and Replace Faulty RAM or Hardware

If the error persists, hardware issues (like faulty RAM) may be the cause. Test your memory using Windows built-in tool:

  • Open Windows Memory Diagnostic:
    Press Win + R, type mdsched.exe, and press Enter.
  • Select “Restart now and check for problems”:
    The tool will scan your RAM for errors. If issues are found, consider replacing the faulty module(s).

If youve recently added new hardware (e.g., a graphics card or SSD), try removing it to see if the error stops.

Method 7: Reset Windows (Last Resort)

If all else fails, a clean install of Windows can resolve deep-seated system corruption. Back up your data first:

  • Back Up Important Files:
    Use an external drive or cloud storage to save documents, photos, and other essential files.
  • Create a Windows Installation Media:
    Download the Windows 10/11 Media Creation Tool.
  • Perform a Clean Install:
    Boot from the USB drive, select your language, and choose Custom: Install Windows only (advanced). Delete all partitions during setup to ensure a clean install.

FAQ About INVALID ACPI TABLE (0X00000045) Errors

Q: Will updating BIOS always fix this error?

A: Not necessarily. While a BIOS update can help, its not guaranteed to resolve the issue if the problem stems from drivers or system files.

Q: Is this error hardware-related or software-related?

A: It can be either. Hardware issues (like faulty RAM) often cause frequent crashes, while software corruption (e.g., driver conflicts) may appear after updates or malware infections.

Q: Can I safely ignore the BSOD if it doesnt repeat?

A: If the error is intermittent and your system runs fine afterward, you can monitor it. However, its best to apply fixes to prevent future occurrences.

Q: Does this error affect my data or files?

A: The BSOD itself doesnt corrupt your files, but frequent crashes can lead to data loss if unsaved work is lost during a crash. Regular backups are recommended.

Q: Why does the error appear after a Windows update?

A: Updates sometimes introduce bugs or conflict with existing drivers. Rolling back updates (via Settings > Update & Security > Recovery) may temporarily help while waiting for a fix.
