Hi all,
I hope you can help me.

And if so, I can do that for years and he has never had any problems ..

Safe Mode etc. Start Windows normally. Perhaps it happened to you that the computer fell into power saving mode but could not be "woken up". After about 25 minutes of switching off the screen, the hard drive lights up and I thought it was due to the fan. I've already unscrewed the case because the direction is grateful for solving the problem.

What could that do?
