macos ventura extremely slow

this is my situation, i bought this iMac from a friend, it's a 2013 with 16gb of ram, ssd and i5 quad-core, also a geforce gt 750..

the system is running ventura with opencore.

it was working very well, smooth and fast at least for browsing the web and social media, light tasks,

today i decided to clean some files he left at the machine, i also deleted his user and created a new one for myself.

after that moment, it started running very veryyyyy slow, even for typing right here now,

to open any system setting, its slow, it takes a lot, idk what happened?

any clue to this?
