Asus laptop Model UP 80V - installed windows 10, no problem. Next time I turned it on it came up with a blue windows graphic then moved to a blank page with a moving rotating circle. Now after several reboots all I get after the windows graphic is a blank screen, no arrows, cursor, anything. Tried rebooting numerous times, hard reset removing battery and holding down the on key for 20 seconds. Something appears to be running because I can hear the fan. The power button has a steady light, and the hard drive light flasher pretty regularly. I can't do anything. Any other ideas?
