003 rack not getting detected

[brainsout]

Hey,
Would really appreciate help with this, will be starting the 201 course tomorrow so I'm trying to figure this out ASAP.

Basically, have had my 003 rack about 18 months, no problems with it in the past. Use it on my Vista Ultimate (Dell) and an older Macbook. The primary computer is the Vista one though. For some reason, earlier today when I started it up, it just wouldn't get detected by my Vista. I tried a different firewire cable, and then my Macbook and to no avail. Also tried switching between the two ports on the 003 itself.

If it makes any difference, I only upgraded to Pro Tools 8 a fortnight ago but it had worked in the meantime. The only thing I have done, that was out of the ordinary was switch from using the firewire port on the front of my Dell to the firewire on the back of the Dell. This was definitely done when the 003 was off along with the computer. I'm aware it can cause problems but I wouldn't have thought to this degree.

Lastly, I've tried putting the 003 rack into the firmware "reset" mode... still nothing. The "link" light remains lit when its connected to anything though.

I'm hoping thats enough detail and its not specific to the computer or operating system... I'm a bit worried and hoping I haven't somehow fried (both?!) firewire ports on the 003!

Help?

*EDIT*
When I say the "link" light remains lit, I mean the one at the back beside the firewire ports. Not the "1394" on the front. Any suggestions and I'd be very grateful....
