Hello everyone. I have a Dell laptop, XPS 15, my specs are on the attached file, like requested. I hope i did everything right, if not, please let me know. I used to play Diablo 3 on this laptop, highest settings possible, and it never gave me any problem. Now i quit Diablo and moved to an online game, called Atlantica Online (Atlantica Online), and then the problems started. I guess it's important to say i play this game for a very long time now (3~4 years) and never had any trouble with my old PC (a Quad-core, 4gbs ram, 1gb video), and my brother also play this game on his laptop (a i5, 4gbs ram, onboard video). When i try to run it on my Dell, first, it started to overheat. I started monitoring my CPU and GPU temperature, and it'd go from 50ºC/122ºF (idle) to 90ºC/194ºF just a few seconds after i started the game. To solve this problem, everytime i run the game, i run this app: ThrottleStop (ThrottleStop - Performance Adjustment Tool for Core 2 / Core i CPUs) so i can 'underclock' my CPU to 75% and turn off the Turbo feature of my i7 (Note: I also tried to run the game without underclocking my CPU and it restarted anyway). When the problem occurs, screen goes blue, sometimes purple, there are some squares, like a chess board, it's all messed up. I see the mouse still works (it moves a big square when i move the mouse) and keyboard still works aswell (capslock light). But if i try to press any button, the computer will freeze and i have to hard reset it. I hope you guys can help me solve this problem, i really like this game (it's the only one i play actually, but if it's the game's fault, i'll stop it, just want to be sure). Thanks in advance, Thiago. PS: English is not my native language, so if i didnt make myself clear enough, i can try to explain better.
