Access Violation problems with PTLE7 / mBOX

[Royal Boob]

Hi all,
This is my first post on here.
I've been having problems with Pt 7.0 pretty much since I upgraded in December.
The programme runs fine until the Pc is shut down and restarted. Then upon launching Pro Tools, i'm greeted with an Access violation notice and the programme closes. I've reinstalled several times. I've even reinstalled windows from scratch incase there is any conflicting programmes, but to no avail.

Please can someone point me in the right direction. I just want the sod to work!!

Thanks
