Inspiron 5515 - intermittently have to reboot to get keyboard working

Question

I'm pretty stumped by this. I replaced the keyboard in my Inspiron 5515 months ago (due to some of the keys peeling). Initially, I did not properly seat the ribbon cable, but got this sorted out. The keyboard works most of the time. However, it will intermittently (not daily) become unresponsive, until I reboot. This happens when the computer is stationary, on a table, so I don't think that this is an issue with the ribbon cable or connector. I updated all of the Dell drivers and recently updated the BIOS. Does anyone have any ideas as to what the problem might be and how I might rectify it?
Thanks
