Getting Web Pages To Load Across Multiple Browsers

I have an old Dell PC running Windows 7. I just bought a new Samsung PC with Windows 8 loaded. Both have Charter Security Suite loaded. Both access the internet via my WAN connection. I have three browsers loaded: IE, FF, & Chrome. On all three browsers, my old W7 PC loads pages faster. On the Samsung, the pages are slower to load and I have to refresh (hit F5) to get them to render properly.

Other than the OS, I cannot figure out what is the root of this problem. Evidently, a lot of others are having it too (based on reading several posts found using an internet search). The WAN is the same. All 3 browsers have the issue. The virus software is the same. I have nothing else loaded on this new PC.

I'd be happy to try some options and do further testing to try to fix this issue. It does not happen every time with every web page, but it happens much to frequently to ignore. Whenever I come across a slow page, I test it on the old computer and it pulls up quickly.
