I have a Dell XPS M1530 laptop, over the last couple of weeks, the screen would all of a sudden change to look crazy pixelated, sometimes it would freeze like that, but most of the time it would automatically reboot. It started happening more and more often, and the last day or two, sometimes you would go to use it, and it would be on but the screen would be black, and you'd have to reboot it several times to get it to come on. Also, it seems like the bottom is a lot hotter then normal. Is this a video card issue or could it be something else? I'm not a computer guy at all, so any thoughts would be appreciated, thanks!!
