How to fix error 0x0000009c in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'mdsched.exe', and press Enter. Choose 'Restart now and check for problems'. This tests your RAM for errors, as faulty RAM can trigger machine check exceptions. If errors are found, replace the faulty RAM.
2. 2 If RAM is fine, check your CPU temperature. Download a tool like Core Temp or HWMonitor and run it. If your CPU temperature exceeds 90°C under load, your cooling is insufficient. Clean dust from heatsinks and fans, and ensure the CPU cooler is properly seated.
3. 3 If you have overclocked your CPU (via BIOS or software), reset to default settings. Enter BIOS/UEFI and load 'Optimized Defaults' or 'Load Default Settings'. Overclocking can cause instability and trigger this error.
4. 4 Update your motherboard BIOS to the latest version. Go to your motherboard manufacturer's website, find your model, and download the BIOS update. Follow their instructions carefully. A BIOS update can fix compatibility issues with CPU and RAM.
5. 5 Check your power supply. If it's old or insufficient for your hardware, it might cause voltage fluctuations. Consider testing with a known-good power supply or using a power supply tester.
6. 6 If the error persists, the CPU itself may be failing. This is rare but possible. Contact the CPU manufacturer for warranty support or consider replacing the CPU.
