Hi Don,

A problem I see on a rather regular basis meets the description of the problems you report.

It may be that your hard drive has been reset to PIO instead of DMA access by the System.

Read and understand this:

And here is a line by line tutorial in enabling DMA in Win7:

I've never seen a case where doing this hoses the computer and I'd say that better than 90% of the time it is the cure for the problem where I work part time at the test benches.
