No updates for a while

Was having problems with my graphics card since I updated to windows 10 (was my first mistake..).
I called Microsoft technical support and they have messed my computer up more than it was. I can no longer access anything on my desktop, they reverted it back to windows 8 and now nothing works and they ended the call..
Tldr; No computer as for now, will pray I can get my important info off the computer and do a full restore.
Hopefully I figure something out before Monday.
