My laptop just stopped working suddenly. The screen went white and froze while making a beeping sound. I eventually did a manual shut down using the power button. Waited a few minutes and tried a cold boot. The indicator lights come on, I can heard the drive and the fan runs for a few seconds before the entire computer shuts down again, and will eventually try to reboot. The indicator lights go on and off, fan goes on and off, drives make noise but the screen remains black. I didn't back up any files and fear the repair price will cost more than the computer itself. I have an HP PAVILION ENTERTAINMENT 6000 series (DV6408NR/Turion)
