Computer Specs" 2 X 8GB of RAM Intel Core i7-6800k GTX 1070
In the past couple of months, it has felt like my RAM has been decreasing, but every time I check Task Manager it still says I have 16GB. But today I was messing around a bit more in Task Manager and I noticed if I change the Memory display column from value to percent it will tell me that a program using 500MB is also using 20% of my RAM putting my total ram at 2.5GB, not 16GB. Now I know that's not true because I can see in Task Manager that I'm using 4GB at some points.
This may be unrelated but my internet speed has also experienced a decline in the same period.
