Yeah, it's a laptop. A graphics card failure wouldn't surprise me, as my computer tells me that the "display driver stopped working and has recovered" error I've gotten has happened over fifty times. The card I have is probably old and can't handle all the use it gets....
I'll try to update the relevant drivers before giving up on it, but my computer may be dying anyway. I think I would be better off to get a desktop computer, since my laptop is probably getting overworked....
