How to Fix Error Code 0x00000124
-
Check System Temperatures
Turn off and unplug the computer before cleaning internal components. Use anti-static precautions when handling hardware. -
Run Windows Memory Diagnostic
Save all work before restarting as the memory test requires a system reboot. -
Update BIOS and Drivers
Never interrupt a BIOS update process as this can permanently damage your motherboard. Ensure stable power supply during update. -
Test RAM with MemTest86
Handle RAM modules carefully and only touch the edges. Use anti-static precautions to prevent component damage. -
Check Power Supply Stability
Turn off and unplug the system before testing power connections. Be careful when using multimeter around electrical components. -
Reset BIOS to Defaults
Removing CMOS battery will reset all BIOS settings including date/time. Take note of current settings before resetting. -
Test with Minimal Hardware
Ensure proper grounding and handle components carefully during removal and installation. -
