No, just happened re7cently after a restart of my computer

So whenever I press 'C' or '7' instead of just those characters in types '7c' ('&C' if capslock is on) and whenever I press 'Enter' it types ']' as well as what usually happens when you press 'Enter' e.g. skip the the next line or searching something. I have gone into control panel and messed around with the language settings with no prevail and my keyboard drivers are up to date. I am using a Logitech MK700 with Windows 10 installed. I've searched everywhere and cannot find a solution so any ideas or solutions would be greatly appreciated.

So I was wondering if spray painting a case fan (i.e. a Noctua P12) would cause dangers to the inside of my system, such as will it flake or spread particles that could harm hardware? The average temperature of my Gigabyte G1 1070 is around 50 - 55 degrees celsius (under load) so would that kind of heat ruin the paint?
