In the last couple of days I am having a hard time booting the laptop. When I turn on the power button a few lights come on but he lapt op is not booting up. After turning it of and on 6 to 8 times it will boot up. I do notice a blinking blue ligt next to the "cap lock" key and the small key "end/num lk". Any suggestion to what's happening. Before shutting down the previous evening there was a download from HP.
