The slow dribble of information here is not the way to get yourself help.

When did this start happening? Did it ever work OK? On what Pro Tools release? Where is your Sandra report?

There is a whole lot of things to try troubleshooting under "Help us Help You" up top of each DUC page, you only seem to have tried some of them, but not all? And *always* suspect plugins, you don't seem to have tried removing them yet. And uninstall any floppy drives in Windows device manager (yes even if you don't gave any floppy drives) and remove any optical discs from drives...

When you post again, include a clear list of exactly what you have tried, and a Sandra report and the other information.

And include what interface are you running and what driver version (not that you think it's up to date, what actual version shown in device manager).
