Guild Wars 2

This is unacceptable. I go to launch the game, that’s fine, but as soon as I hit “play” the game instantly goes to a blackscreen with a blue window bar at the top with a corrupted “guild wars 2” in the top left hand corner. I can’t play the game or do anything with it. Before this issue only occurred If I launched the game, closed it after playing, then tried to go back to it later, but now I can’t even play at all.

My graphics card is a Nvidia geforce gt 430, which should be able to run the game on lower settings. Does anyone else have this problem, or have a fix for it?

I’d take a screenshot of the issue, but the black screen error just completely crashes my computer and I have to hard reboot, every single time.

Updating this. So I was finally able to play today, for about thirty minutes or so lag free before a heavy lag set in and my character was essentially frozen. Anyways, i went to launch the game again just now and I get the blue screen of death, but with some information that may help solve this problem.
*Stop: 0×0000007E
(0xC0000005, 0xBD260BFE, 0xB79ED8CC,0xB79EDSC8)
*nv4 – Disp.dll – Adress BD260BFE, base at BDO12000, Dates temp 503F8b2a

Now, I have no idea what this means, but maybe somebody else could clue me in? Maybe a lack of data issue?

edit

I just went to attempt to play the game after rebooting, and unfortunately I am met with the same black screen and the inability to do anything else until I restart my computer.
