Watching 1080p videos is just a slide show. Computer overheats quickly even it's cleaned. CPU usage hits 100% when opening only two chrome tabs. I saw that they can edit 720p videos and play light games on it however my laptop struggles even web browsing.

Could you be more specific about it? Slow on every task or some certain tasks? Did you try to re-install clean/original Windows 10? Other versions of Windows are also slow too? Probably doesn't support NVMe.

I have an Asus X505BP laptop with AMD A9 9420 dual core processor and 8 GB DDR4 memory with 240 GB SATA SSD but it's running extremely slow and buggy even on Windows 10.

I'm curious about does it support NVMe SSD's or it only supports sata type M.2 or it should boost the performance after upgrading to 12 GB or 16 GB?

How did install or Upgrade your drivers? If you use driver installer, Now clean reinstall Windows and don't use any Driver upgrade or installer programs. I think Really you no need's Driver updater or installer programs. Only install your drivers with Windows Update and Your motherboard web site. Have a good day.
