Eleven rack won't boot

[groovq]

Hi my eleven rack won't get past the boot screen! I've tried both reset options, unplugged USB etc but still won't get past the boot screen. The serial number ends in 0H

She lives a sheltered life not leaving the office so not misuse! Actually doesn't get used as much as it should!

I'm in Australia and got the unit via avid Australia/new Zealand because of multiple replacement units of another product so there is no retailer to contact for a replacement/fix.

After looking around here it seems quite a common issue. I'm not having much luck with avid and m-audio products it seems! Update: after looking at similar issues hear reminded me about the tuner not being recognised sometimes and stuck on one note.

Maybe I have one of the old dodgy batch

Any ideas for my next step?

Cheers, chris
