Ok I'll try that, thanks. The thing is, apparently I can't do this on my broken PC right now, because the Setup doesn't progress. It just stay at 0%... So I have to prepare the USB stick somewhere else. I have another question for you r72019, please. Let's say, this USB boot step doesn't work, what then? Is it even a possibility? Or would this mean there is something fundamentaly broken with the PC? As long as you can access BIOS, F12 on boot, you would be able to see the one time boot (and list of available devices) option on your screen.  You just need to go to the link using any PC running windows 10 and it will properly format a bootable USB flash media for you.  Passing the ePSA hardware check is a good sign.  I probably would suspect the ongoing issue may be an issue with the hard drive, either physical or perhaps malware, since you're not able to download or save anything, and get occasional failed boots..  Another thing to check to address the PC running really slow is that you aren't running out of RAM.  Or that you don't have a background process eating up system resources (whether malware, malfunctioning program like AWCC, etc.) but that would be cleared by a clean install. 
Hello Dell Community, I really need your folks help, please. I need to find out what the problem with my PC is. My Computer (Aurora r7) has some weird problems latley. For one thing, my computer is starting this way now (Checking media presence error on startup). After a while, the computer starts Windows normally and I can log in as usual. There it goes on with a variety of other problems. I cannot use certain websites and services: No matter which browser. Internet is great. I can't access YouTube, Netflix, and Spotify to just name a few. Many other things work normally, like most products from google and various websites, while others do not or hardly. Installations and updates: Many installations and updates just don't want to work. Microsoft Store apps and Alienware programs are amongs them. They load / install forever and in the end nothing happens or they end up with an unknown error message. I have no idea how I even managed (after a reboot that I did) to update windows, which brings me to the next point. No PC reset possible: No reboot possible, it loads for ever and then it fails. I have no idea what to do, please help. What's the problem here? The hardware? Is my motherboard or processor just breaking down? Corrupt windows files? What should I do?
