My 12347890 and down right keys dont work

My 12347890 keys stopped working when my HDD was replaced because it was broken, my keys used to only work for aroun three or four hours before they stopped working, then i had to restart the coputer, but now it straight up doesnt work at all, my down and righ keys didnt work after my HDD got replaced, is there a way to fix this? My computer is a Windows 10 Home

 

Sadly, you told us nothing about the computer. We don't even know if a PC or notebook. . I am guessing notebook but that is just a guess.

Have you tried a different keyboard?

If a shop did this repair, take it back.

 

It is a PC, sorry, i dont really know what information i have to put here

 

Its better to have too much than not enough. We can weed out what's not necessary.

My advice remains the same - I would try a different keyboard. The fact this is a PC and not a notebook makes things easier - or at least it eliminates a few possibilities - like a pinched cable inside the case.

 

Hi gsans, Welcome to WindowsBBS . Like Bill has advised, we need more info to be able to help diagnose problems.

This indicates to me that your keyboard was faulty before the HDD was replaced.
So following Bills advice should be your starting point.
