Well, I think I found the problem. My last OS was 32 bit and I've now changed to 64 bit. Most things worked within acceptable parameters on the 32 bit system, so I started to narrow down what the common denominator could possibly be. The conclusion was that my Chromium Browser was the link between my computer and Youtube, so I changed the Browser to Chrome 64 bit and the problem appears to be fixed.
