Similar issue for me too. Here is my post about it: http://forum.square-enix.com/ffxiv/t...sh-BSOD-issues

Just a couple questions for you:
1. Have you gotten any blue screens of death while playing?

2. How exactly does the game behave when the issue occurs? Does it immediately crash? Does the game freeze but still stay running until it closes? Can you still hear the music and other items going in the background when it freezes/crashes?

3. How long can you go before this happens? Does it happen after a certain amount of time (say an hour or so)? Does it vary? Does it do it every single time you are logged in or only sometimes?

4. Have you checked your Windows Event Viewer for any errors thrown? Can you if you haven't? I'd be interested in seeing what Windows may have recorded there for the crash. I would look in the System and Application sections
If you aren't familiar with Event Viewer you can check it by doing the following:
1. Click the "Start" button.
2. Right-click on "Computer" and select "Manage" in the right-click context menu.
3. In the left-hand panel expand "Event Viewer."
4. Expand "Windows Logs."
5. Select "System." Scroll the list and note anything with a red error icon.
6. Select "Application." This is the important one really.
7. Look at the time stamps and match them up with the time the game crashed. Check to see if there is an error message. If there is, try posting it in the thread for comparison purposes.
The message may look something like this:
Faulting application name: ffxiv.exe, version: 1.0.0.0, time stamp: 0x5215cce1
Faulting module name: ffxiv.exe, version: 1.0.0.0, time stamp: 0x5215cce1
Exception code: 0xc0000005
Fault offset: 0x007cd875
Faulting process id: 0x2238
Faulting application start time: 0x01cea1252b339068
Faulting application path: C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\game\ffxiv.exe
Faulting module path: C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\game\ffxiv.exe

5. Also, what type of hardware are you using? CPU? Motherboard? RAM? Video Card? Are you using the latest driver for your video card? Have you updated the chipset drivers and BIOS for your motherboard?

6. Are you completely up-to-date on Windows Updates? Have you installed any new ones in the past few days? Are you running any anti-virus software?

Sadly, with the forum being flooded with posts complaining about the server maintenance and login restrictions (which shouldn't be in this forum seeing as there's nothing that tech support can do about it; it's a decision that was made well above their heads), I wouldn't expect to get any help any time soon.
