My machine is working very slowly and I am unsure why. Even loading a webpage in chrome or starting up spotify takes ages. I have 787.24GB available of 999.35GB for storage. 8GB of memory installed. I have tried emptying the trash and some other things with no luck. Any help would be great.
Start up in Safe Mode by holding down the Shift key on start up and let us know if your problem persists.
Have you tried running an antivirus scan with malwarebytes or another program?
