I finally fixed the issue!
I downloaded all of my motherboard drivers. I installed the first driver which was the Intel Chipset drivers, and instantly everything was opening much quicker.
After I restarted, everything opened instantly. Right clicking on icons or folders was quick again, opening Chrome was quick, opening other windows like the Networks and Sharing window loaded instantly.
I've been running my computer for more than a day straight now (not shutting it down, no reboots etc.) and everything is still running great. Before it would take about a day until everything was super slow.
Thanks to everyone that helped me resolve this issue! +Rep for all!
