Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
To start with Id like to say that not all computers are fully compatible with Windows 10. Also, sometimes the upgrade install doesnt go smoothly, and windows 10 doesnt work so well.
We can try some fixes, but it may be that we need to downgrade to windows 8 and keep your files.
First, we need to open and admin command prompt. Here's how to do so.
In that window.. Type this command.
dism.exe /online /cleanup-image /restorehealth
Hit enter.. Watch the command prompt window.. It should so a percent sign showing the progress. As long as it does that and doesnt give you an error, then the command is running. Be prepared, this may take an hour, to two hours.
Once complete.. restart the computer.. Then, we need to check and see which drivers failed to install.. Heres how.
Please press the windows key on your keyboard , hold it down, and press R
Onscreen should be a box that says Open / Run . In that box type in,
devmgmt.msc and then hit enter.
Now, inside the device manager windows that shows up, were looking for any device that says unknown or unrecognized device, and it may have a yellow warning mark next to it. If you see any of those devices, let me know what they are labeled as and what category they fall under.
