my minus key keeps pressing. there are moments when it does and when it stops. it already keeps pressing when i try to log in, but it stops a bit so i can open. i downloaded an app to disable it, but it still keeps pressing. however, when i physically press it with my finger, it doesnt type, which led me to believe the problem is not in my keyboard. i tried to go to device manager and uninstall the program under keyboard, it asks me to restart and problem is still there. please help
