Ok so heres the problem...I have been experiencing problems with my graphics card that usually results in my screen going black, except for the mouse. When i minimize guild wars a pop-up reads, Guild Wars has encounterd an unrecoverable graphics driver error...It gives a link, but im not sure i want to install and re-install, im only 15 and its my dads computer, u get it

The problem usually occurs in certain parts in eotn/gwen in asuran areas at the moment. I can't even sign on because im stuck in an asuran city and as soon as i choose my char it goes black. All of my other characters work fine. I encountered this problem earlier in nightfall at once specific city. I signed in on another computer and mapped out of the city, later when i signed on my own computer it loaded fine. My graphics card is an...Intel(R) 82865G Graphics Controller....any advice??? do i have to buy a new one to go without problems or should i result to logging on my friends computer again? thanks in advance
