Guild Wars 2

So, my game’s been crashing a lot lately and when I try and run -repair on the program, it always causes my computer to crash with a memory failure. I ran the prime95 program that was suggested on the GW2 site and everything came back fine. So, I then assumed that the problem was with the game data itself and deleted all GW2 data on my computer. I am currently reinstalling the client. Everything seems to be running fine now, but I wanted to know if there was anything else I could do should the problem persist and I am also curious as to the probable cause to this dilemma. Also, as a side note, I am currently running windows 8 64-bit with the geforce gtx 860 graphics card and all my drivers are up to date.
