Certain keys work intermittently

[irakspir]

My pc woke up one day and decided that the buttons : esc,~,tab,caps lock,1 and q should go on an irregular strike for reasons i don't understand. When i push them, they sometimes work and sometimes do not, usually not. Did all software updates I could find including BIOS, disabled/enabled/updated drivers, ran hardware diagnostics that repeatedly claimed everything is fine and yet the problem persists. Rest of the keyboard works fine, it's just those specific furthest-left buttons that do this. Usually the issue gets bandage-fixed if i press the keys a lot of times or hold them down for 10 seconds but it always comes back

Please use a can of compressed air and blow to the area under those key.

Hope this helps
