starting to get on my nerves

I did a post a couple days ago asking if anyone really knew if my graphics card had a problem and gw was kicking me off blah blah

well it hasnt been kicking me off as much now that factions came out but whenever i pass this certain line outside of frontier gate it kicks me out saying graphics card failure

this also happened when I went outside of yaks and took around 10 steps away from the warp which then it kicks me off

its not a one time thing either I've tried this several times and it keeps on doing this to me

can anyone help?

just to update this I was talking this over with some guildies and it appears that its been happenening to other people just like which I have also noted and found out that it only happens when you are near a warp or actually trying to go throught a warp and then it kicks you off
