In any circumstance - typing in a message box, just pressing it randomly it freezes my PC for a split second and I have no idea what is causing it. I have restarted pc and done virus scans but I have a feeling it is my motherboard.. can someone help?

I don't have another keyboard, also I haven't tried the onscreen one yet but I will now - EDIT: it still happens even with the on-screen keyboard.

It seems to be fine after a restart and then as soon as I launch Overwatch it starts happening up until I restart PC again. I went back to windows 7 and it is still occuring
