You have too low and slow ram. Your Graphics chip is also not suited for Fortnite.
Your Laptop seems like a "work" laptop rather than a gaming laptop...
Also, when loading fortnite,it comes up with a sign saying my amd graphics driver has known issues and is not up to date. however, i am unable to update drivers; it tells me they are up to date
You are most likely getting the error that your graphics drivers are not up to date as your GPU is very old, dating back to 2008 and according to the AMD website the last update for that GPU was in 2013.
