Did your team member install the driver softpaq for you?

Yes he did same things you said.

thank you very much for your help..

But Now I have new problem.

My HP Z820 is freezing, especially when I am using Google Chrome. İt's monitor HP Z24i is freezing. at this time no mouse and keyboard input..

I need to shut it down and restart again to continue my jobs.

I use this computer for forensic purposes at all.

The Z820 USB3 motherboard chipset is a Texas Instruments product whereas the Z840 uses an Intel motherboard chipset for that.  You can confirm this by doing a Google search for Z820 drivers and going to the "Driver-Controller" section, and in there you'll see:

"Texas Instruments USB 3.0 xHCI Controller"

If you do same for Z840 you'll see:

"Intel USB xHCI Controller Driver"

Sounds like you may now have a mishmash of drivers installed.  You may wish to try using PS2 keyboard and mouse.  You can get nice new HP ones off eBay for cheap.... HP still seems to be making these.  Also, download the TI driver set and try reinstalling those.
