Guild Wars 2

This is really frustrating!
I just got my brand new PC and it supposed to run GW2 without any porblems…
But after 5-15 minutes of playing it shuts down the computer to a… sleep-mode?
But I cannot turn it back on until I restart the power source.

My old PC (which hardly ran GW2 on low graphics) never had this problem.
Now that I finally have a PC designed for gaming, it seems to have problems with GW2?
Just my luck…

We’re taking back the computer tomorrow. I’m depressed.

I also have this error saying ‘Out of memory’ …
I have it all the time, to be honest. It really screws my gameplay (especially when it shuts the game during a story dungeon).
Reading through this thread, I’ll try playing with low graphics. I hope that helps.

Also, I have texture bugs a lot. I don’t know if that’s connected to the error. It probably is.
Characters, the map, my inventory, or the trading company’s window… They often turn blue-green colored like on this picture :

I hope I’ll find a way not to have this error and texture bug so often.
