Question Windows 10 keep freeze but mouse work

[Denme]

I have built a new pc but an old spec (very tight budget build). After installing the os everything went fine but after 2-3 days of use it become worse, the system always freeze for a minute even if im not running anything, i cant even open control panel. the cursor keeps moving and responding even tho sometimes it lag, i suspect it is from the ssd it self or maybe there is something wrong with the os
