Computer randomly restarts while playing.

[RaineMagus]

Had to think of this one for awhile.

Honestly, it's a bit odd that FFXIV would cause a reboot ... whereas Prime95 + Unigine do not. Additionally Tomb Raider 2013 and Metro should've caused higher power consumption than this game. I'm fairly stumped there as these issues tend to be power related more often than not.. That all said, how intermittent is the duration between these reboots (do you ever make it to the hour mark)?



--You do mention that you have a "superclocked" / factory overclocked card, yet again it's fairly hard to believe that any instability from that card would show in FFXIV and not Metro or TombRaider. If the card / driver locks up, Windows 7 will attempt to issue a TDR (timeout display recovery) .. Often when this happens you'll just get a popup in the system tray following the screen briefly going black, and the system resumes execution thereafter. Sometimes though under certain drivers, the TDR can go horribly wrong where the OS is incapable of restarting the drivers / GPU, and the machine either hardlocks (indefinite blackscreen), or Windows attempts a restart.


-You might try making the following registry change to increase the TDR timeout period, incase Windows is mis-detecting a driver lockup. It'd also be wise to check the Windows Event Log (specifically under "system") to see if there's anything reported immediately before the shutdown.

============================================================
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"TdrDelay"=dword:0000000a
"TdrDdiDelay"=dword:0000000a
============================================================


Another thing you could try doing (just to see if it's somehow graphics related) is forcing your 660's clock down to the stock (eliminating the factory OC) with a tool such as MSI Afterburner (or even lower). While it's not that easy with a 600 series card to provide a voltage bump (pretty much impossible in software), lowering the clocks will achieve the same effect (increasing stability).

Beyond that Geforce 660's overclock / display driver instability, another good idea might be updating your chipset drivers if you've not already. (often overlooked)


Try running the Intel inf auto update tool with the "-overall" argument. This will FORCE the installer to overwrite all chipset drivers on the machine / purge old versions. *note that it's best to do this from SAFEMODE*
