Guild Wars 2

Hey guys, so my games been crashing non stop. I do sometimes notice it keeps crashing at around 50 mins but still it happens randomly too. I will edit this post and include all the error codes that pop up. Oh sometimes it doesnt fully crash too. When it doesnt completely crash the screen freezes and if i alt-tab out and come back in the game starts working again. I have tried to do a clean install of my gfx drivers, update my motherboard, and running the game in windowed mode.
Error Codes:

Looks like bad RAM. Try removing and re-seating your memory sticks.

Sometimes, you can tap on an intermittant memory stick (with something plastic) and get it to fail. Try this with the game running and you may find a bad memory stick.
