I turned off my computer correctly last night, tried to turn it on this morning and it was stuck at the splash screen. I already tried disconnecting all peripherals and pressing the power key for ~30 seconds, tried again and I'm still stuck at the screen. I ran diagnostics (F12 at start up) everything is fine. At the F2 screen my only option for SATA is ACHI so I could not try that method. I recently upgraded to W10 online so I do not have any physical ways to boot via USB or CD. Please help.
Just to clarify, it is NOT looping, it is just STUCK at the Dell splash screen with the "Diagnosing your PC" notice at the bottom.
