Wtf Error!!

I love guild wars but it makes me mad, I will be in the middle of a mission and then BAM! Next thing you know I get a critical error, at first I thought it was my PC overheating because that is just how it is with W/C and no fans, . But I then decided to turn off in windows restart after error and then now it just closes Guild Wars down. Anyone have any clue what it is? I already re-formatted once and also reinstalled the game, I am getting a new case (it's in the mail) in about 2 days so I will have to swap all my stuff out and see if it is my cooling since the case I am getting has awsome cooling capabilities. If you have any clue what this problem is being cause please do noe hesitate to post or to give me a PM since it is bad when I will be getting far in the game and then the next thing you know I have to restart the whole entire missions or farming or trading or whatever I am doing

i would imagine it will be a heat issue if you have no fans, try it with the side of the case off and a house fan blowing on the motherboard and gfx card.

GW runs stress tests to check your pc is stable so try turning off any overclock you have especially on gfx card.

Do what now? I hadnt heard about that. Is it automatic at game start, or is it a test program, like the UT2k3-4 benchmarking? And yeah, try the "redneck solution", the fan blowing in the open case. If that clears it up, you need fans, or better ones.

well I am getting my new case (thermal take armor) tommarow so I will just wait and see, well I am gonna be painting the inside and swaping out the leds for the fans but other then that we will see!

A long shot, but could your pump be playing up? If it's not shifting the required amount of fluid then that fluid could easily overheat!
