Help! FFXIV Won't Stop Crashing, Sometimes Takes Computer With It

[EdanR]

Hi there. My partner and I have been experiencing a lot of issues playing FFXIV on Windows 10 in the past few months on my custom-built desktop, with the game crashing frequently and the computer sometimes crashing along with it. We tried a lot (which I will list below), including replacing the SSD and RAM, in order to try to fix this.

For a while, the computer crashed almost every time FFXIV did, until it eventually reached a point where it was stuck in an endless loop of BSODs that resulted in Windows being unable to actually start up. As I recall/have taken pictures, the consistent BSOD message was “PFN_LIST_CORRUPTED.” We got on the phone with Microsoft Support, who took hours of our time and got us to wipe both of our drives, all while failing to do a clean install of Windows. We then took it to a repair place that got a clean install of Windows done successfully, though they could not save our data. We reinstalled FFXIV, seemed like we were good to go, and then the crashes came back after a week or two. Ever since the clean install, it has been mostly the game crashing on its own instead of the game crashing and then a BSOD coming with it, but BSODs have been becoming more common in the past few days. “PFN_LIST_CORRUPT” is even back with a vengeance.

Initially the problems seemed to have something to do with things were split between the C: and D: drives, now it seems it may have to do with memory errors. Below is a list of some of the error messages we have received from game crashes, followed by BSOD messages, followed by the steps we have taken to troubleshoot.

FFXIV errors:

1. The instruction at 0x00007FF94C0EDC30 referenced memory at 0x00007FF94C0EDC30. The memory could not be written.
2. An unexpected error has occurred. Exiting FINAL FANTASY XIV. 2020-12-14_11:31

(We have gotten many errors like this one, filenames are not always the same, this is just the one for which I had a picture handy to copy from.)

BSOD stop codes:

1. PFN_LIST_CORRUPT
2. MEMORY MANAGEMENT

Steps taken:

1. Moved the .exe files for FFXIV out of the Steam folders so that Steam could be “tricked” into reinstalling it, in an attempt to replace the old .exe files
2. Replaced SSD
3. Replaced RAM
4. Clean install of Windows 10 (an unintentionally wiped both drives)
5. Renamed “Steam Library” file
6. Uninstalled game from C: drive and reinstalled on D: drive (and replicated step 6)
7. Turned off all overlays (Steam, Discord, GeForce)

Anything you folks can think of to help us stop the crashes would be greatly appreciated.

Hello

I would try the fix at the other forum you listed your issue’s on first.. This seems to be a driver issue according to microsoft page .

[HEADING=1]Cause[/HEADING]
This error is typically caused by a driver passing a bad memory descriptor list. For example, the driver might have called MmUnlockPages twice with the same list.

If a kernel debugger is available, examine the stack trace: the !analyze debug extension displays information about the bug check and can be helpful in determining the root cause, then enter one of the k (Display Stack Backtrace) commands to view the call stack.
