I am having ongoing problems with my computer freezing, and then sometimes 'crashes' and a message pops up that says intel graphics accelerator for windows 8 (r) stopped responding and has been successfully recdovered. Is this wird that it says windows 8 when I'm using windows 7?

I've had my laptop for about a week now and the touch screen has stopped working last night. The last time I used it I turned it on sleep mode, then when I came back home, it wasn't working anymore. I tried calibrating it and running the troubleshooter, but nothing has helped.

I have a 2 year old Dell Ispiron One 2305. About 2-3 times a day the screen just goes black. It is a lighter, back-lit black, compared to the dark black when the machine is completely off. The power button is a constant white when this happens.
