HP Envy 17t-s100 will not use all the ram and CPU cores

HP Recommended
HP Envy 17t-s100
Microsoft Windows 10 (64-bit)

Hello, I had the drive in my old laptop die 17t-s100 Envy. So I got a replacement drive to replace it. Due to this I needed to reinstall Windows 10 using a USB. After doing so I realized that my laptop was using only 2.2 of the 13.8 GB of ram that was on the system. It says the 13.8 GB of ram is hardware reserved. I have already tried changing the max memory in the msconfig. I checked the BIOS and it does show 16GB. This is the same ram I had before and that came with the laptop so shouldn't be any issues there. I have also already tried reinstalling the BOIS from HP and reinstalling Windows 10. I have also noticed after doing some small searches that only 1 CPU core is being used and shown as well which it is a i7-7500U so it should have 2 cores. These are the only issues I can see as windows works fine and the drive is completely working. Is there anything else I could do to try to get the RAM and CPU working properly? I am out of ideas
