Guild Wars 2

So I tried as recommended above, however, it seems I have to underclock at least by 150MHz and 20 mem. Though it rebooted once at those levels, so I underclocked to 175 and 25, and so far, so good.

Thanks for the post, Milkduds. I will try that when I get home from work today and see what happens.

Before I seek help for my problem, here are the specs for my computer:

Intel® Core™ i7 3820 Processor (4x 3.60GHz/10MB L3 Cache)
Liquid CPU Cooling System [Intel] – Standard 120mm Fan
16 GB [4 GB X4] DDR3-1600
NVIDIA GeForce GTX 660 – 3GB
Gigabyte GA-X79-UP4 — 4x PCI-E 2.0 x16
500 Watt PSU
180 GB Corsair Force GS SSD
Windows 7 64bit

Windows is up to date and all my drivers are up to date.

As to my problem:

I recently bought GW2 3 days ago, and from initial gameplay, about an hour in, my computer screen goes black and then my PC reboots. If/when I try to play after that, it’ll reboot every 10-20minutes.

Yesterday I spent time adjusting in game graphic options. I dropped the settings to best performance, which put everything at low, and was able to play. Throughout the day (maybe 6-8 hours game play time?), I was able to bring most settings up to high and play for a few hours, with LOD distance, shaders, and postprocessing to medium (LOD/shaders) and low (postprocessing). However, after I switched to a new character and area, it started rebooting and now does so almost instantly.

Guild Wars 2 is the only game on my system that does this. I can play Skyrim, Civilization 5, and many other games just fine, with no issue.

I have tried the advice stickied in regards to Nvidia blackscreen issues (changing power-management to best performance) and adjusting anti-aliasing, to no avail.

Any advice out there?

I’ve read some posts about adjusting clock speeds/power settings, but am a little nervous about that and not sure how to do it without messing more stuff up.
