Windows 10 x64 Very Slow on new Acer Aspire 3 A315-15 laptop.

May 27, 2018
I bought this laptop two days ago.
It came with Endless OS (Linux).
I installed Windows 10 Home OEM because i can't install Windows 7 or 8.1 (drivers not working).
Specifications: Intel Celeron(R) N3350 1,1ghz - 2,4ghz. I clocked it to 2,4ghz.
4gb ddr 1333mhz ram.
Hard Disk seagate 500gb 100mb/s read and write.
When i browse web, go to settings, task manager..etc cpu and hdd 100% usage!
I really need to buy ssd, because i think Windows 10 can't work well with no ssd installed.
Any help will be good. Thanks!
