Here is my problem: my pc was doing just fine when all of a sudden it started going on and off line and takes forever to load a page if it even does. I keep refreshing after it has stalled for like several minutes. Eventually when it comes back on it will load the page really fast. But if I have to select different things to get to a specific page or site it takes forever again. I am totally frustrated by this crap. Everything is new except the network card. When I upgraded to Win 10 I found an all-in-one for my motherboard but do I need to update my internet card too? It's a RealTech and the other night Windows told me that something should be done there but while I looked at it I ignored the warning. Should I find the update to it too?
