I have a somewhat new computer ( 2 months old) with 8gb of ram. My issue is that upon start up my pc is saying that my memory usage is around 84% or 6.7gb/8gb. I checked my processes and my total ram usage only adds up to around 500mb. This is kind of a big issue because it is stopping me from being able to play any games. I was hoping that someone here could give me some insight on how to troubleshoot and eliminate this issue. It only just started maybe 2 days ago.

So far I have tried:
- Turning the computer off and then back on
- Turning the computer off and unplugging the power supply
- Talking to useless tech support from iBuypower

Any help would be appreciated. When I talked to tech support for iBuypower ( where I purchased from) the only advice they gave was reinstalling windows.
