Windows 10: Problem upgrading W8.1 to 10

My old computer runs on Windows 8.1 pre installed during purchase. I am replacing the Hdd with an ssd and upgrade to W10 as fresh install. After installing W10 using procedure by booting via usb. It asked for my key. I used the W8.1 key, but the sw did not recognize it to get my free upgrade. What should I do?

Windows 10 1709 System Restore problems...

That seems to be an attempt at Option 2 in the tutorial, which requires you to
a. Boot to a command prompt (Did you?)
b. You then seem to be mixing steps 3,4 and 5, thus your command is incorrect.

I suggest Option 1 is easier.

If you still have problems, please repost listing each specific step and saying which option from the tutorial you are using. Thanks.

 

Video card or RAM need upgrading?

Memtest: no errors after 10 hrs.
I'm going to perform the Primetest, later on. Get back to you on that.
I'm going to take it step by step, guys. I need to find the problem with this current computer. I might have to upgrade some components, so that it is still runnable. As for the new one, yes....i will build on it later. I need to find something decent 'gaming experience', all suggestions appreciated. THanks.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.
