Internet Speed Slow Only On One Computer

I've recently upgraded to AT&T 300 Mbps and I did get what I bargained for most of the devices in my household. Wifi getting around 250-300 and ethernet getting 300+. I have good speed on every device except for one, my personal computer, I'm currently connected through ethernet (cat5e), and I can barely get 100 Mbps. I thought it had to do with the range, but I tested the speed using my phone at the location of my computer which got ~260 Mbps, but my wired connection only gets 90-100.
P.S. : My computer is the only one on windows 10, I'm not sure if that could be a factor.

Edit : I think it has to do with the cable, I've just checked my ethernet speed and it's capped at 100.0 Mbps, while my other pc has 1.0 Gbps, should I upgrade to a cat6 because my personal PC is decently far away from my modem.

Some simple points I will mention.

  1. Prevent programs from automatically running when you start up your computer. ...
  2. Delete/uninstall programs you don't use. ...
  3. Clean up hard disk space. ...
  4. Save old pictures or videos to the cloud or external drive. ...
  5. Run a disk cleanup or repair. ...
  6. Changing the power plan of your desktop computer to High Performance.

Let me share an awesome info-graphics which helps.
