Keys sometimes don't work?

My 45RTFGVB keys stop working randomly at times. It started with an issue when my Dell Inspiron would have issues turning on. It would start up then shut down or it simply just wouldn't start at all.
So I took the screws out and took out the keyboard to access the hardware. I looked to see if anything was unplugged. I could see nothing noticeable so I put the laptop back together. I pressed the power and it turned on. But after a short while this issue came up. See right now they are working as I'm typing this sentence but when I first started typing I had to use the on screen keyboard. What would the issue be? Dust? Oh and now they aren't working BTW. What is the issue?

I can see no visible damage to the keyboard. And if it was the ribbon then wouldn't all the keys be disabled?
