After bluescreen on the pc everything different?

I just had a bluescreen and the following happened: google chrome away Minecraft worlds all gone all versions gone (the whole folder!) Logged out everywhere and all login data (steam Minecraft yt) do not work! What's this? From playing on steam the folders are suddenly in the middle of my desktop? Is that normal after a bluescreen? Error code was the usual one for scanning and Windows texting it was still collecting data. LG thanks

If you really can't log in anywhere, I would consider that someone had access to your computer and / or your accounts and changed the passwords. It's best to check your emails.

No, everything is normal on the cell phone, it is only possible on the pc. Something has happened before, but I put it on myself. The whole thing has been since I've had a hell of a lot of stress with networked people… I have internet too.

Then I don't know what it could be.
