I ran into a problem because my C drive was completely full, showing 0 bytes available. I attempted to move several Steam games to my D drive, which has just under 1 Terabyte of free space. However, my PC didn't show any confirmation that the games were moved. To make space, I started deleting old files in my downloads folder and temporary files. After that, I tried restarting my computer, but now it seems "offline" and I can't log in with my password or PIN. I'm using Windows 11 on a Cyberpower C series computer.

If your internet is acting up, try disconnecting from Wi-Fi and logging in with your last used password or PIN. If that's not working, you could tether your phone with a USB or use an Ethernet cable. Also, deleting files doesn't always free up space unless you do it right. Check out tools like TreeFileSize to manage your storage better!
It sounds like you might not have actually bricked your PC, which usually means it's broken beyond repair. Worst case, you could reinstall the OS if needed. For your connection issues, it’s hard to pinpoint the exact cause here since you didn’t change anything major.
As a rule of thumb, try not to fill your drives over 75% to keep things running smoothly. If you did have backups, great! Otherwise, if you only deleted some downloads and temp files, you should be safe. To really clean up space, try using the shift+delete option to permanently erase files instead of just sending them to the trash.
If you're stuck, have you tried safe mode? It might let you fix things or delete some games to free up space. Another option is to create a bootable USB with Linux to clean up your drive, but be careful with that since it might let you delete things Windows would usually block. Also, how did you try to move those Steam games? Use the built-in option, okay?
Definitely try safe mode first! If your friend can help, that USB method could work wonders to get a clearer view of what's taking up space on your drive.

Yeah, the fill percentage is a big deal! Ideally, try to keep it below that 75%. But nowadays, you can push it closer to 100%, just don't make it a habit.
