Complete PC lockup/freeze

Just got a new pc and am having trouble with the game. Randomly, I get complete lockups of my computer forcing me to restart it. The screen will freeze, I'll get a constant loud whirring noise through the speakers, and can do nothing else.

I only have this issue with ff14. I run every other game at max settings with no issues.

The game runs flawlessly up to that point too. At max settings, I was running an average of 150 fps. I tried limiting frame rate, and run a gpu temp monitor thinking it was overheating but it seems to be fine.

Specs:
Gtx 980 ti superclocked 6gb
Core i7 6 core processor watercooled
16Gb ddr4 ram
Windows 8.1

All other games run ultra settings, no issues. Only happens with this game. Any suggestions?

I get pretty much the same issue. Usually seems to happen in a duty or dungeon but can happen outside of that as well. Screen goes black with a whirring noise from speakers and need to do a hard restart of my computer. I never have issues in any other game many far more intensive. No overheating issues. I also get no issues running video and cpu intensive benchmarks. Yet 5 minutes in ffxiv jumping into a duty and decent chance of the game crashing my comp.

i5 4690k, gtx 970, 16gb high speed gamer ram.

Try notching back the overclocks to see if it becomes more stable. XIV isn't optimized very well and strains every subsystem at once--many of those other games likely do a much better job distributing work across the GPU and additional CPU cores and likely don't thrash the drive and RAM as bad either.

You guys may not have pushed clocks up or trimmed RAM timings yourself, but the higher performance level hardware you have will be configured to run faster clocks then the reference designs...so they are in fact over clocked compared to the typical specs in play. We've seen such configurations do weird things in the past like this and notching things back slightly often improves stability.

No idea how to notch back whatever my OC my card maker may have put on. Using an Gigabyte GTX 970 4GB OC version. My msi board has afterburner installed but its disabled. Also have the Gigabyte OC guru but also disabled. So its set to what Gigabyte sold it to me as :x

Not quite sure how to notch back the overclocks myself. One thing I did notice though, is I had this same problem happen for the first time in another game. It happened about 3 minutes after I turned AA up to max.

I solved this problem on FF by keeping my AA at the normal, and also turning down Ambient Occlusion I think it was.

Its funny though, because I am not overheating when the computer seizes up. Could this be a driver issue?
