Device manager yellow flags

[Lucifer29]

Hello fellas, new guy here. I own a Lenovo z50-75 laptop FX-7500, R7-M260DX running on Windows 10. The problem I get when I safe boot in device manager is the one showing in the attached image. Also, when I restart my laptop, I get the window showed in the other image, and my screen flashes black for about 10 seconds and then its all fine until the next time I restart it. In addition to that, today when it happened all usb ports and the ethernet port were not working at all, until I restarted for another time. Device manager says all drivers are up to date, and I havent found anything regarding this issue in Lenovo's support website. Thanks in advance for your help.

Do you currently have an external monitor connected to this laptop ? ?

If so it's missing a driver.

No, I don't

Did this system come with 10 or did you upgrade to 10 from 7 or 8?

It looks like its using a generic driver for the integrated video.

Well there was one plugged at some point as it's showing there...

Do you have the Driver CD that shipped with the Lenovo ?

It came with 8.1 and I upgraded to 10 myself. After the upgrade, I reinstalled all the drivers availiable at the Lenovo support site to make sure everything was compatible with 10. And to be honest I didnt have any problems with 10 since I upgraded, this issue came up much after that.
As for the Primary IM Controller, I understand that it does no harm for me to unistall it since its not working properly. But what about the Generic PnP monitor? I have never plugged any other monitor on my laptop

Well I never had a monitor in my life to start with  ... And I bought it from a retail shop, Driver CD was not included

Then in that case it's safe to remove/uninstall the plug and play monitor....

The IM controller however is neccessary...re-visit the Lenovo site to see if they list it.

The Monitor likely refers to the laptop screen. Usually it shows more 'fully'; eg. my Thinkpad shows "Wide viewing angle & High density FlexView Display". It may be as Dave mentioned that the Graphics Chip driver isn't installed.

I've been trying to look into what the "Primary iM Controller" does. Best I can figure is it is "Independent Multicast". It looks like it does something with hardware information as it has a few other "info" dlls that appear to retrieve hardware information. It may be part of the "Customer Engagement" Service. It's also shown in Device Manager on my Thinkpad T550.

Device manager says all drivers are up to date

Device Manager says a device is up to date if it cannot find a new version on the Windows Update site. It can't be trusted as actually telling you there is no newer version.

here is the driver page for that laptop. It looks like a new driver for the graphics chip was made available a few days ago.
