Even without BSOD ?

I didn't reinstall the game, but repaired it a couple of time.

And settings are already low.

May the errors come from RAM ?
I removed one a few months ago, it seemed to be defective. The last 4 Gb are the same ones.

I made an account to just reply because I'm having the same problem!!

Nexuss Did you figure out what the problem was?

I have an Intel core 2 duo 3.0ghz, 8gb RAM, Nvidia GTX550ti, 750w Power supply and that should be enough to play Guild Wars 2 with at least medium settings. I'm going to try a clean driver installation using what koolkat77 suggested and also going to use memtest and check my ram. Koolkat please help me!!!

I have 2 blue screens but dont quite remember what they said...I know it said something about graphic driver.
