MACHINE_CHECK_EXCEPTION (0x9C)
What is this error?
A fatal machine check exception occurred. The CPU detected an internal hardware error that cannot be corrected.
Common causes
- CPU hardware failure
- severe overheating
- power delivery instability
- CPU overclocking beyond safe limits
- motherboard fault
How to fix it
- Disable all overclocking immediately
- check CPU temperatures
- run CPU diagnostics
- consider RMA

Bug check 0x0000009C (MACHINE_CHECK_EXCEPTION) is one of the most serious BSODs. It means the CPU itself detected an internal hardware error — a calculation error, cache error, or bus error that it cannot correct. This is always hardware-related. The most common cause in gaming PCs is CPU overclocking beyond what the silicon can handle, or CPU degradation (especially Intel 13th/14th gen Raptor Lake). Overheating can also cause MCEs. Fixes:
- IMMEDIATELY disable all overclocking in BIOS — reset to defaults,
- Check CPU temperatures during load — if >95C, the CPU is overheating,
- Run Intel/AMD processor diagnostic tool,
- If errors persist at stock settings: the CPU is likely degraded or defective,
- For Intel 13th/14th gen: apply microcode 0x129+ and check Intel warranty extension,
- If MCE persists at stock with good temps: CPU needs RMA.
When to seek help
If this error keeps happening after trying the fixes above, it may point to a deeper hardware or system issue. Consider professional help if:
- The crash occurs across multiple games or applications
- You see the same error after a clean Windows install
- Your PC is less than a year old (could be a warranty issue)
- You smell burning or hear unusual sounds from your PC
