The avilable physical memory is much lower than my total physical memory ....

• 
  The Physical Available Memory I have is much lower than the Total Physical Memory
  
• 
  I have a 8 GB PC running but when I open the task manger for example android studio is taking about 1.855 GB and it's written above that this is 80% of the memory ..... I thinked that another program is consuming in the background so I switched the view
  method in the memory so every program is written in front of it the memory usage percentage and I was shocked when I saw that android studio is consuming about 70% !!!! so the computer is just using 2.83 GB out 8 GB of my memory !!!!
  
• 
  I searched a little bit online till I found that i can see something called the physical available memory ... and the total physical memory
  
• 
  the total physical memory was 8 as expected and available physical memory was about 2.59 GB !!!
  
• 
  A lot of articles online said that a part of your memory is being consumed by hardware parts like the graphics card ..... but not as much as mine
  
• 
  I tried a lot of solutions but non of them worked in my case .... But I noticed Something a little bit weird .... every time I restart the device the physical available memory changes .... sometimes 6 sometimes 4 ... some times 1.5 !!!!!
  
• 
  I tried also to reinstall my windows an installed a fresh new windows 10 education ..
  
• 
  has any one face this problem before ?! or any solutions ??
  

 

High installed physical memory, very Low available physical memory

Got a new computer and my Installed Physical Memory (RAM) is 8.00GB whereas my Avaiable Physical Memory is 370MB.

I game on my PC and I am getting very low FPS with many lag spikes in all of the game I play, I'm assuming this is the problem, but if anyone notices anything in my specs that could be effecting my pc performance, id appreciate some help <3
