That's a frustrating problem! Sounds like you've really tried everything. A blank login page often points to connection issues, despite the VPN attempt. Maybe there's a deeper system configuration problem. It almost feels like the computer itself is being "smashed" by something, though hopefully nothing that dramatic! On a completely different note, have you ever played Solar Smash? It's oddly calming after dealing with technical headaches. Good luck getting it sorted!
