Answer:
Disk defragmentation
clear up storage
restart the computer
Step-by-step explanation:
PC's going slow is a very common occurence nowadays and what i had to do to usually fix slow computers is to first use disk defragmentation which will automatically sort our files and put them in the right order.Second is to delete any unnessary files,folders,programs that i no longer use or its just sitting there eating dust and finally my last resort is to restart the pc which usually helps fix most of the issues including slow PCs which might be caused by some errors during startup.
Hope this helped
