I was using my desktop PC all day yesterday, and it was working just fine. Never got any errors, lag, or anything. So at night, I shut it off, and went to bed. This morning, I turned it on and went to go have breakfast. When I got back, I realized that the loading bar was stuck. That is, the loading bar in the very first boot screen, the one that says "DELL" (if you have a Dell computer...). It's the one that comes before the Windows boot screen. It's also where you can access the boot menu and all that. So yeah, that's where it gets stuck. It was stuck... I'd say around the 80% mark. So I turned the PC off the "unsafe way" (holding down the power button) and turned it on again. This time, it went a bit further in the loading bar and got stuck. I've tried this about 3 more times, and every single time it gets stuck at the same place. I've never had this problem happen with ANY computer, so I honestly don't know what to do. I tried accessing the boot menu, but then I realized that for some reason, everything plugged in to a USB port doesn't seem to work. The keyboard is off, the mouse is off, and my external HDD is off as well.
