PC freezes after being left idle for a few hours

Had the exact same symptoms as OP ever since i upgraded from a Ryzen 7 1700 to a 3700x on a Asus Crosshair VI Hero. Tried pretty much everything the internet suggested although i dont even use Corsair Link or NZXT CAM, i've been using the old Aura Sync to control my RGB. 

For the people still searching for a solution, try to disable Global C-state control in the BIOS: 

I tried that as a last effort before returning the processor back but after1 week of use i have yet to experience a "freeze" with the C-state Control disabled. 

I will report back in case i get another freeze but so far it seemed to solve my "freezing" problem.

Hi all

Seems like the issue is resolved for me and the few people who read my post. Glad I could help. Almost a month without the aforementioned symptoms.

I uploaded a video showing my unresponsive pc to further narrow down the problem and mitigate possible false diagnosis:

If you have symptoms like that then please try to disable "Global C-States" in your BIOS. (If another motherboard vendor is used then google where you can find the setting)

Also, credits should go to Creativem0nster1 over on the Linus Tech Tips Forums because he first suggested the solution, yet it got too little attention:

HUGE thanks to this guy, im trying to spread the word.

Note: The setting "Global C-States" is responsible for the reduced power consumption when your PC is in idle. But I'll take a working system over a bit more power draw at idle any day of the week ;)

This solved my problem! Went into BIOS and disabled C-State. Computer has not froze for 2 weeks since making the change. Good luck to all! Thank you so much, @McK-4268!

Thanks for your idea.

I disabled C states in bios. It was set to auto.

Wish me luck :)

Cheers!

UPDATE: two weeks, no freezes or crashes.

Thanks McK-4268 for passing the tip along!

Hey Guys 

Just an update.

My PC hasn't froze since uninstalling Corsair Link 4 in January 2021. I still get a random blue screen about once a month, this is GPU driver issue and not related to the original problem i had.

shocking to see so many still experiencing these freezes. Microsoft really need to lay off the new updates and focus more on testing these updates before releasing them. Every new update seems to cause more problems than it fixes. 

Long gone are the glory days of Windows 7 :(
