Client frequently crashing (Not NVidia)

I used to have a similar issue with loading and immediate crashes before with ATI cards, but checking LoD in the graphics setting seemed to fix this error.

However, now either the same problem has come back, or something similar has come up.

Yesterday I loaded up Mor Dhona and when the screen started to load, I crashed to desktop. Loading up the game again resulted in the same thing. Over and over. So I restarted my system, and it seemed to load fine (albeit way more slower than usual).

Today I was in my house crafting and it crashed to desktop. Loaded again, and immediate crash to desktop. Loaded a third time, and I didn't immediately crash but opening my inventory, all the icons were grey squares. I waited a minute to let it load, tried to access my retainer (who didn't actually show up), game crashes to desktop.

Thinking this may be like yesterday, I rebooted the system and attempted to load the game. Again, crash to desktop immediately after loading.

I reinstalled the game (imported my prior settings), patched, put my graphics to the lowest they can (still with LoD enabled), and still crash to desktop nearly immediately after I changed the settings.

The below is the windows error I am receiving:

Funny enough when I was loading to get the appcrash data, it let me play for 15 minutes. As soon as I switched classes and it loaded the gear, it crashed me and then reloading caused it to crash on the character select screen this time.

I've done some diagnostic checks on my RAM and HDD, and both seem to be checking out okay. Graphics card drivers are up to date, and same with windows updates. Not sure what else to check out now.

Won't let me even choose a character now, seems to crash immediately upon loading the character select screen. This game seriously needs a repair/file integrity checker.

Played with a graphical/RAM intensive game (Witcher 3) for about a hour inbetween the loading, and haven't seen a single crash, overheat or even lag spike. Thinking it's somehow related only to FFXIV's client.

Do you have Raptr, nVidia Experience, or anything like MSI Afterburner installed that hooks into the video output? Having more than one of these programs running usually makes the video card run hotter and a lower frame rate than it should. Some of them (eg Raptr is installed with recent AMD drivers) hooks into every game by default, and other video capture software will have a fit if it's installed.

The only way I've ever been able to get FFXIV to crash is via video capture software.

Only things I see are:

- Memory Issue (unstable Overclock?)
- GPU Memory Issue
- Anti-Virus blocking Steam
