So I recently bought the HP Pavillion Gaming laptop 15 - ec0100AX. It has 8 GB Ram , 1TB HDD, Ryzen 5- 3550H , Nvidia GTX 1650. I searched and found that 2gb ram is reserved, but when I check my task manager it shows that only 3.7 gb ram is usable. Can someone please explain this ? Also why does it show as 100% active for my Disk C when I just attend online class ok Webex. Also will adding RAM make it any better?
