Fortnite started taking up 100% of CPU & Memory

[fadithebest2002]

Randomly out of the blue 2 days ago fortnite randomly started taking up nearly 100% of my cpu and memory.It causes really bad game stutters every few seconds so its really unplayable.And the thing is,i can run every single other game fine like gta v,rainbow six siege,etc.I have 8 GB of ram and im sure its not my pc that is causing this.My fortnite has a sloid 100 fps and 15 ms but the game is still managing to take up my cpu and memory.if i can get some help id appreciate it thanks!

List your specs like so:

If you're on Windows 10 check your system resources while on idle. Have you tried uninstalling your GPU drivers and reinstalling it with the latest revision?
