Hello,

I have exclamation marks on these 3 "devices" and pc could not find updates by itself, and in "events" section it says: "device install required"
How can you help, if you even can so?

Thanks.

Hi:

What is the full model number or product number of your PC?

Use this guide to find that information...

HP Desktop PCs - How Do I Find My Model Number or Product Number? | HP® Customer Support

All I can tell you not having any idea what model PC you have, is that you need to install the Intel chipset installation utility, and Intel management engine interface driver for your specific model PC.

Hi again, 

Product number of PC is: C8N27AV
Okay, I will try with that.

Thanks.

You're very welcome.

I don't see the Intel chipset driver on the support page, so use this one...

Intel Chipset Installation Utility

Then here is the Intel Management Engine Interface driver:
