Windows 10: Windows Explorer.exe restarts and restarts Wifi

Hello,
Maybe you can help me. A friend of mine got a pc from a friend and I cleaned it and installed windows 10 new.

I used a wired connection to make everything and this works fine.

Now the problem, she uses wifi and from time to time the explorer.exe resets itself and the wifi connection got lost and needs to reconnect.

So for gaming or talking its pretty annoying.

I tried it with removing the 2h20 update cause of the many bugs it did not solved it.
I tried a wifi card (PCIe) and also the same issues. With the other devices in the network is everything fine.



I also tried the chipset driver to install new and with the wifi card drivers.

Winver: 2004 (Build 19041.746) but also tried the 20h2 update.
The system:

Windows 10 Pro 64 bit
Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz (4 CPUs), ~3.4GHz
NVIDIA GeForce GTX 1060 6GB
Samsung SSD 840 EVO 120GB (system)
WDC WD10EZEX-00KUWA0 (1TB HDD)
16 GB DDR3 memory

thanks for any help or advice

:)

 

Random restarts

when you start the computer up press F8 repeatedly until you get a list of how to start windows, choose do not automatically restart on system failure. if your getting bsod's list what your getting here so we can further help you. IF the system is not getting bsod's and still restarting as you say then i would look into getting a line conditioner for your computer as you might be having power issues.

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?
