Weird problem with Mouse and Keyboard

On so since about 2 weeks ago ive been experiencing weird occurrences with my mouse and keyboard. From time to time the hardware acts weird but turning off windows and on again helps with it for abit but then come backs it comes on and goes away roughly once a hour for 5 minutes.

What happens on keyboard is the delete key doesn't work or doesn't type anything what ever i click on the keyboard or the letter for example instead A does an A with a line above it.

Or the mouse when it happens the left click sometime double clicks or when click on link to just switch on it open the link in a new window or right button does nothing.

I was using this mouse for 8 months and the keyboard for 2 years and 8 months with both no such problems before.The mouse is Logitech G502 Proteus Spectrum RGB and the keyboard is Corsair K50.

So far i used C Cleaner to turn off start up programs and delete some registry, also used Malware Anit-Bytes is deleted some files but still occurs, also adwcleaner it deleted files but still same and i also tried JRT and nothing still same errors occur.

I didnt have such problems before the Windows Updates but then it was fine 2 weeks with them updates.

Did you create a restore point before doing housekeeping.
For any major housekeeping &or involve in registry setting, there is a need to backup that portion of registry in case of problem arise.
For keyboard keys issue, unplug that particular key and check for any blockage, such as pin and any small items stuck inside.
This is quite common for keyboard do have gap where dirt and small item can go inside.
Or turn it upside down to shake for any small items to come out.
