mdsched.exe, and hit Enter. - Choose Restart now and check for problems.
- The system will reboot and run the test automatically.
- Check the results after the test finishes.
If errors are detected, you may need to replace your RAM modules.
Step 4: Update Device Drivers
Outdated or corrupted drivers may trigger hardware errors.
How to update:
- Press Windows Key + X, then select Device Manager.
- Expand categories like Display Adapters, Processors, and Network Adapters.
- Right-click each device and select Update driver.
- Choose Search automatically for updated driver software.
Alternatively, visit your hardware manufacturer’s website to download the latest drivers.

An outdated BIOS can cause system conflicts and errors.
Warning: Updating BIOS incorrectly can cause serious issues. Proceed carefully.
How to check BIOS version:
- Press Windows Key + R, type
msinfo32, and press Enter. - Look for BIOS Version/Date.
Check your motherboard manufacturer’s website for BIOS updates and detailed flashing instructions.
Step 6: Scan for Malware
Malware can corrupt system files and cause errors.
Use Windows Defender or third-party antivirus software to:
- Perform a full system scan.
- Remove any threats detected.
Step 7: Run System File Checker (SFC)
Corrupted system files might trigger ERROR_124.
Steps to run SFC:
- Open Command Prompt as Administrator (right-click Start > Command Prompt (Admin)).
- Type
sfc /scannowand press Enter. - Wait for the scan to complete and follow any repair instructions.
Step 8: Perform a Clean Boot

If the error no longer appears, re-enable services and startup programs one by one to find the culprit.
Step 9: Check Hardware Physically
If software fixes don’t work, it’s time for a physical inspection.
- Open the case and check that RAM, GPU, and CPU cooler are seated properly.
- Look for bulging or leaking capacitors on the motherboard.
- Test components individually if you have spare parts.
Step 10: Consult a Professional / Consider Hardware Replacement
If ERROR_124 persists despite all these steps, your hardware may need professional diagnostics or replacement. It might be time to contact your PC manufacturer, a trusted repair shop, or consider upgrading computer parts.
