Google-search for "download free SPECCY".
Download, install, and run the SPECCY software.
Run it as soon as you turn the computer on.
Run it again every 15 minutes, as you use your computer.
SPECCY will report the temperatures of your disk-drive, your motherboard, your CPU, and will report the speed (RPM - revolutions per minute) of each fan inside your computer.
I think that your computer could be overheating, and shutting down.
After it cools down, you can restart it, and use it for a while.

> Or it the sign of a bad AC adapter ?
Yes, that is a possibility.
Touch the AC adapter -- is it "hot" or just "warm" ?
After your computer shuts-down, take an electrician's "multi-meter", and measure the Voltage and Wattage being output from the adapter. Compare to the values printed on the label on the AC adapter.

> And now my pc is not giving the time to install that software. It get off before that.
I think that your computer is overheating, and is proactively shutting itself down, to prevent damage.
What is the temperature of the warm air being exhausted from the computer? Is it "hot" -- 60 to 90 Celsius ?
Since your computer is getting "worse", I think that it is time to seek professional trouble-shooting, before you totally "kill" it.

> When its [temperature is] passing 80°, CPU fan RPM increase and noisy.
> But i didn't hear this before.
That is what the motherboard is supposed to do -- recognize the "excessive" temperature, and speed-up the fan, to try to cool the CPU. Of course, faster spinning generates more noise, and that is what you are hearing.
What programs are you running, such that the CPU is getting that hot?
Games? BitTorrent file-sharing? What anti-virus software are you using? It might be doing a "full" scan.
Microsoft released security-updates at 10 AM Pacific on 10/10/2017 -- earlier this week.
Could Windows Update be the cause of the extra CPU usage?
> is there any chances to fan speed failure?
If you are hearing the fan, running at full speed, and SPECCY is reporting such high temperatures, it has not failed.
