Hello.
I have problem with my DELL INSPIRON 11.

When i bougth it, it had win8, but i upgraded it to win 10.
It was working good, but from last 4 months i have strange problem.
When i start it, keys on keybord (1QAZ TAB CAPSLOCK and SHIFT) dont work at all - no matter what i do.
They start working after some time, but even then they dont work properly. FOr example it happens very often when i press any of those keys to make one letter, in exchange i recieve 2 or even more letter - it looks like sensitivity of the keys doesnt work properly.
Is it problem with keyboard drivers? From mechanic point of view keys are working so maybe keyboard isnt damaged.
Anyone have seen similiar problem?

Thx for help

Plug in a keyboard, does it still happen?

Since you did a dirty install you can do a fresh install of windows 10 from the iso.

Don't worry about a key as its bound to ur mobo from the upgrade

Yes, you can create a bootable USB version of the disc. I haven't used a CD/DVD drive in four years and have installed numerous OS'.

The process is very straightforward. If you find Microsoft's guide unsatisfying, there are multiple tutorials in your reach through Google.
