Does anyone have a suggestion? My computer shuts off randomly, while I am on the internet,but that is the only time I am on the computer, also. Did it twice now this weekend, but has done it a few times also in last couple months. Screen goes black, then blue screen with red letters 'Out of Range' appear, and computer shuts off. Then starts up again, but now the internet is off of course, and I must start over again. Had a computer person look at it, and she could not find anything wrong, and it never shut off on her. I am computer DUMB, so any responses would be greatly appreciated, in simple terms.Thanks.
