Random actions executed

Hello ,

My name is Vlad , and im here seeking for a little help.I hope this is the right section .  My problem started few weeks ago . I was running a game , chating in-game when suddenly my keyboard started to go crazy . When I was pressing "a" , it would type "aaaa" , etc . I said to myself that is not a problem , tested it on my laptop , the same . So keyboard broken , went to buy a new one . ( a cheap one tho) . Got home , tested , it was the same . Changed few settings in control panel -> keyboard as I found on google . Worked fine 1-2 days , when things got worse . Without touching my keyboard it would press random keys , turn volume up and down , capslock on/ off . Disconnected the keyboard , still the same . The problem is random and can be there for 5 to 30 mins . Tried to re-format my harddisk 2 times , completely wiped everything . Tried 2 types of windows 10 too . The only option that I can think of is probably a hardware problem , cleaned my computer of dust 2 days ago . Got just basic knowledge about hardware so i might be able to solve simple tasks if its needed . Oh and scanned anti malware , anti tdss rootkit , used anti-virus .

Hope that anyone who knows about it can help me trough .

Thanks and have a nice evening .

Use another USB connector on the computer?
