My hp compaq nx5000 notebook won't start up ~_~. When I push the power button, nothing happens. When I push the cd rom button, it opens; when i put a disk in and close it, the hdd light blinks, the optical light blinks, the fans whir a few seconds, then it stops; nothing at all ever comes on the screen. I think it's something to do with the power cord. Like a wire inside frayed, so it can't power it up; though I'm not sure. . Am i right in what I thnk the problem is?
