You're welcome.
Wish I could take credit for the information, but I can't.
When my friend's machine crashed like yours, I went into a panic as it was I who had installed something that caused the lockup
But the great resources of Aximsite came to the rescue and saved me the cost of buying a new X5 for him:D
Good luck in the restore, glad you were at least able to get to the white screen, it took me 15 minutes to get there with all the key combinations and my fat fingers!
