Acer Aspire 5750g constantly turns itself off?

I need urgent help. My notebook Acer Aspire 5750g goes out all the time. Have now renewed the thermal grease cleaned the fan even from the inside.

Because the CPU always had 100 ° now I'm between 30 and 50 °, but he just wanted me again two times in a row greased even though I wanted to install only Office and otherwise had nothing to do. He is also pretty slow. So bad he is not from the performance or?

Anyone have a hint on what that could be, or how can I find out where it comes from?

I had a similar problem, * Fast Boot * could help turn off.

Enter the Search Bar "cmd" at the bottom left, right-click on it and run as administrator
* enter powercfg -h off * (without this *)
Restart the computer

if it still does not work, I advise you to restore your system.

For the speed of an SSD could help.

A reinstallation could help.

I would try a BIOS reset. A notebook without SSD with Windows 10 is always inevitably slow, so the operating speed you think is so low!

On the notebook is nothing on it have it extra newly set up because it was so slow. What I noticed already. The disk usage is often red and at 100%

How can I replace what BIOS without taking the battery out? Otherwise I have to completely disassemble the laptop again.

Have rebuilt the Windows now is the old Windows 7 on it and the calculator runs without problems and is fast. I have now downloaded a Windows ISO on the Internet. Now my next question: If I install it now, how can I get my network card drivers, and so on. And what about the license key? Can I enter the old win 7 of the laptop?
