I own a HP Pavilion DV9339US computer; it's only 1 year old. After not using for a month, I turned it on and it won't start up. It actually turns on (it has power), but every 25 seconds, like clockwork, it powers off for less than a second and then powers back on again. During this entire time, the screen is black.
I've left it on like this for the past two days, with no change. I'm not sure if this is relevant, but before I stopped using it, it couldn't catch an internet connection; it didn't recognize wireless networks or ethernet.
I need help before I take it to Best Buy and pay 1/7 of the original price for them to tell me it's going to cost more. Any help would be greatly appreciated.
