What is C-STATE-HUNG?
Stuck on hibernation is a high-severity processor (CPU) issue. The processor failed to properly wake up from sleep. Common triggers are dried thermal paste, overclocking too aggressively, silicon degradation and weak power supply. Use the steps below to track down and fix the cause.
Common Causes
- Dried thermal paste
- Overclocking too aggressively
- Silicon degradation
- Weak power supply
Step-by-Step Fix Guide
-
1
Improve cooling and repast
In our testing, Improve cooling and repast alone clears up C-STATE-HUNG more often than any other single step.
-
2
Increase LLC (Load-Line Calibration) in BIOS
Not every case resolves on the first try; the steps that follow cover rarer cpu instability situations.

3
Undervolting
"Undervolting" is the next step worth ruling out for C-STATE-HUNG.

Frequently Asked Questions
The leading cause of C-STATE-HUNG is dried thermal paste, though overclocking too aggressively, silicon degradation and weak power supply also show up in our reports.
The fastest fix is "Improve cooling and repast". Only move on to the later steps if C-STATE-HUNG keeps coming back.
Rated high severity — C-STATE-HUNG isn't immediately destructive, but recurring instances are a sign to fix it sooner rather than later.
You shouldn't need to. Work through the guide above first — a reinstall is only worth considering if none of those steps help.
Not necessarily. C-STATE-HUNG can be triggered by software and driver issues, overclocking instability, or BIOS misconfigurations — not just hardware failure. Run through the diagnostic steps above before concluding the processor itself is defective.
