How can i fix this problem.

My Xbox isn't loading my games i have tried a new power cord deleting my games and apps resetting the Xbox and nothing works i can play Fortnite, but it will take forever to load me into a game and when i do get into a game the graphic will die i can't play no games. I can load into madden but it takes about 15 minutes a then when i try to play i will get stuck on a screen and i won't be able to access my home screen it will just freeze. The Xbox is in good condition, and it is very frustrating not being able to play any games. I would like to at least play my game without getting stuck on a screen or it just simply not loading. I have tried every possible way to fix this issue and it do sent work and i cant afford another console.
