It continued to shut down over and over, so i unplugged everything ut the stuff nessecary to run a computer (mouse,keyboard, monitor,power) and the message finally disappeared.only now its stuck on the HP logo page. and i cant go in to check anything because now the keyboard wont work. it is getting power because it flashes twice. So im getting frustrated because i have tried three different keyboards, both regular and usb. please if you could help that would be great as i havent been able to use my OWN computer for 2 weeks.
