I love my DV7 and have it for years. For a while now I have noticed that I can only use the laptop for about 10 minutes, then it black screens and will shut off. I am attempting to troubleshoot the problem. I do not know if it is a fan problem and the computer is overheating and shutting itself off. Or if it is a chipset problem which affects the video card, or if I just need a new mother board. How do I troubleshoot this problem with the black screen?
