I got DV6-6105tx laptop. Last evening suddenly it got hang with black screen and some noisy sound from speaker (I was seeing video). I got to force shutdown it. Later I tried to switch ON. It is just keep on showing Windows booting icon for sometimes and gets Off automatically.
Once it showed recovery option, but after recovery finish and restart, still it is just showing Windows booting icon.
I understand that you were watching a video when you heard a unusual noise from the speaker and the notebook shut off.
When you tried to reboot it went to the Windows booting logo and automatically shut down. Once it did show a recovery option but once if completed and did a restart it again when to the Windows loading screen and hung.
