my laptop is not working anymore

hi, i recently tried to play because i havent touched my laptop in almost 2 days, but when i turn it on, it started normally, lenovo logo but after the logo appeared the screen turned black, it didnt turn off cause it was not black of no light, literally black screen, i can see my mouse in there but nothing else, i restarted it 3 times and got into the menu of choose an option, ive already tried some tutorials i saw, enter secure mode and restart, didnt work, delete nvidia drivers, didnt work, delete the screen driver didnt work they just reinstall but keep not working, ive already tried restaurating system but it appears a text that says that i should turn on protection of the system in this unit, and i can do nothing more there, i tried restoring my pc but keeping my files, sends me an error that says a problem happened and changes didnt apply, ive already tried the option of startup repair, says theres nothing wrong with my laptop, im already tired, someone knows what should i do? my laptop is a lenovo loq 15ihr8, the ram is 8 normally but i changed it to 16.
