Mouse and Keyboard periodically act strange?

Question

Hey, any advice would help!
For some reason, every so often my mouse and keyboard will both start acting strangely, and have been doing it for quite some time. The mouse will highlight things around it and anything I click in a browser starts in a new tab, anything at all, anything I click on. And likewise, anywhere I click, it highlights around it too. The keyboard acts as if caps lock is on when it isn't and some of the letters/symbols change to other characters. It's starting to get a bit more than just annoying. At first I thought it was just because the mouse and keyboard I had were old, like really old, so I bought a new set of each thinking that would solve the issue, but it happened again this morning. (Only got the new mouse and keyboard yesterday!) Sometimes I leave my computer on for long periods of time if that has anything to do with it, heh.

Any help would be greatly appreciated

Answer 1

If you bought a new keyboard and mouse and it's still doing the same

then I would say you have got a problem with the motherboard.



Your only option really is to put it into a workshop and let them

run some proper tests on it to find what the actual problem is.



Edit ► Forgot to say, leaving it on shouldn't make any difference!



Mine is left on 24/7/52. It's never switched off.



The only time it gets turned off is if I have got to do something that warrants it.

Answer 2

This is most probably due to your motherboard, probably not delivering the required voltage. Your old mouse and keyboard are presumably fine as well. If you are using USB ports for both then consider changing your motherboard because if that's the situation you board can completely malfunction sooner or later and affect processor and other harware aswell.

Answer 3

Start off by looking viruses & malware.

Download, install & run MALWAREBYTES.

What AV are you using? Has it been updated?

You can also run ADWCLEANER..
