Old question and not sure if it is even still an issue for the original poster. I just researched the dv6000 and was amazed in how many people have issues with it. The problem is is the motherboard, and the symptoms include loss of bootup, VERY slow bootup, WiFi stops working, etc. is simply that the MOBO board overheats and fries the video driver chip. The cooling design of this PC is inadequate. Short of replacing the motherboard I do not believe that there is much that you can do. I posted instructions how to reflow the board here http://www.ifixit.com/Answers/View/33368/will+not+power+on Even if you get a new MOBO you might have the problems agai for as long as it has the NVidia chip. It is my understanding that there are now revised board out that have the ATI chip and do not have those issues. Good Luck
