Hi

Sorry cannot help.

"" i have tried every single possibility to fix it""

So I aint gonna come up with anything new am I?

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.

Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
AND/OR
HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

 Next might be to see if there is any config etc details....

Copy, Paste and Save in Notepad, as LBB.bat (not a .TXT) and double click to run.
Preferably run as an Administrator.
OR copy and use the individual command lines as needed.
Post anything non-personal, but relevant please.

So is it loose, broken or something else?  Only you know.

Power On  ESC key and then F1 shows me this on my PC.

So can you photo and post your screen?

[Rohitk_7195]

I thought the problem was fixed but now the WiFi disappeared permanently. 

This is the error it shows now.

Error: the intel(r) dual band wireless-ac 3168 adapter is experiencing driver- or hardware-related problems

Hi

Based on the info so far,  I cannot help any further.

You do not give the model or any real information on the hardware, like the PC's SKU:.

[Rohitk_7195]

I can provide you information about pc. I have tried to get info using Esc button as you asked but system not opening it.

Microprocessor: Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz

If you can see on the right bottom corner, there is only airplane mode option available. Im only able to use internet through USB cable with wifi device. I have also tried to re-install Wlan driver, but showing error.

I hope the given info can help you to find the resolution. 

Thankyou Sir
