Guild Wars 2

I’ve encountered and issue that I’ve heard about some friends having, but only since the most recent patch. Whilst playing, no matter what I’m doing, my screen will suddenly turn black, and enter “power saving mode”. My computer then restarts itself automatically.

I’ve updated drivers to most recent (even though I haven’t had a problem before) and it still black screens after awhile. I’ve checked other threads, and they seem slightly similar, and followed instructions to try and fix. Nothing seems to be working.

Computer specs are as follows:
Windows 7 64-bit
GTX 550 Ti
i7 quad @ 3.40k
8 gig Memory

Sorry for this, and if I shouldn’t do it, I won’t again. Bump.
