Windows 10: Device manager signals problem after fresh reinstall of win 10

Dear everybody!I've just reinstall win 10 on my laptop, and then some issues in the device manager appeared. I attached a picture below that shows the problem.I tried a bunch of options that I found floating around in the net, like scan for hardware changes, which I am pretty sure, that there weren't any; yet I've tried, but no change happened.I was refreshing all afternoon, found recommended optional driver updates, but I really don't know if it's ok to dl them all without knowing it what am I doing.I even tried the virtual agent, but wasn't really much of a help.Can you suggest me what to in

:)

 

Fresh Install of Win 10 without Serial Key?

Looking to reformat a laptops HDD, and then reinstall Win 10 fresh. The problem is it came pre-installed with Win 8 and I did the free upgrade to Win 10. How exactly would I re-format the HDD, reinstall Win 10 and ensure it reactivates properly? I don't see a Win 8 serial key anywhere in the contents of the box.

 

Win 10 device manager problem

Hello,

If the troubleshooters provided above did not help reinstall the driver, you may let Windows attempt to reinstall the driver by restarting your computer. If restarting doesn't reinstall the driver, you can reinstall it manually by following steps below:

• From Start, search for device manager and select Device Manager from the results.
• Right-click the device in the list.
• Select Uninstall from the menu that appears.
• After the device is uninstalled, choose Action on the menu bar.
• Select Scan for hardware changes to reinstall the driver.

Note: You may be prompted to provide the path of the driver. If you are asked for the driver and you do not have it, you can try to download the latest driver from the hardware vendor’s website

Keep us in the loop.

Device Manager "other" entries

After a fresh W10 1703 fully updated install on a 3148 Inspiron laptop, four OTHER DEVICES appear in Device Manager: PCI Data Aqquisition and Signal Processing Controller and three 'unknown devices.' "Drivers not installed; no compatible driver can be found."

Prior to this install several Intel drivers were listed under Programs and Features. likely because they were added after the fact. They are not listed now and Intel's update utility reports nothing missing. SFC is good and PC operation is normal.

The errant entries are redetected at boot even if disabled, or uninstalled via Safe Mode. Suggestions on banishing them for good would be appreciated.
