Hey everyone first time posting on the official forums. I was a ps4 player for years and finally just built a gaming PC for Endwalker.

My specs are:
AMD Ryzen 5 3600X
16 GB Ram
Rog Strix B550-A Gaming motherboard
Nvidia RTX 3060 Ti GPU
Windows 10

Issue:
I can launch the game and get into it okay. The very first time it launched though I froze up during the queue. I reinstalled the game and now I can get into it each time.
However, it seems random when it crashes. It crashed once after 3 hours, then another time after 30 minutes. It doesn't matter what I do because it has crashed while I was idle. Yesterday it lasted 6 hours with no crashing.

I am NOT getting any error messages. The first thing that happens is that I lose audio. Not all audio is lost each time though, 2 of the times all the audio cut out except for the waterfall noise. After the audio cuts I have about 10-20 seconds of movement before my character starts freezing and everything around me freezes until my whole PC is frozen and I have to do a hard reboot. The first time it happened my character froze in a casting stance and I was able to move her in that stance for a few seconds until the boss started disappearing.

I am not very great with PC stuff so I have no idea what to do anymore.

Things I've tried:
Reinstalled the game
Downclocked my GPU
Changed an audio setting where I toggled off the enhancement
Yesterday I changed my power settings on Windows to be on the recommended (balance) one, by default it had been on a Ryzen power mode

I really thought by changing the power settings yesterday it fixed the issue since I was able to play 6 hours before logging out for bed with no crashing.

Today it lasted about 30 minutes again so I thought I'd ask here if anyone has had similar issues.

Thank you for any help!
