Which series of i5 do you have?I will leave here a report of how I can make my PC faster, I have an i5, a geforce 1050 ti, watercooler and a 120gb ssd. First I go to ccleaner and click on records, correct the errors, then I do a cleaning by the ccleaner afterwards I do another cleaning with malwaarebytes and finally restart it helps me a lot, but it erases all caches, saved passwords, computer logins so be careful with this detail but can help.
If not solve formats the PC kkkkkkkkkkkk
