As a general troubleshooting procedure, you want to ask yourself if you have 
made any changes before it stopped working.  If not, and especially if you 
can restart and get it working again, I'd suspect some hardware failure. 
(Assuming the problem is reproduceable - I had times when TDM card stopped 
working with no trace of error.)  Try installing on another box.
