My keyboard is typing 2 letters at the same time

[CosmicMen22]

I have a Compumax keyboard and everytime i type i get two letters (only left side of my keyboard )

If i type 2 i get 12
if i type w i get qw
if i type s i get as
if i type mayus i tab

Those are the only letters damaged right now
(this was hard to write)

Plug the keyboard in to another USB slot and reboot. Still having issues?

Did you try a reboot at least? Maybe do a power cycle of the machine. Power off, unplug from wall for 30s, plug in, power on.

Yes and this problem began two days ago at morning - the computer was disconnected for 8 hours but no change at all

At this point I would try another keyboard.
