No problem layback. didn't see your post at #14
If you can get into msconfig, you could try this: do a "Selective Startup" and set it up like this:
This would turn off all non-essential services. You shouldn't leave it this way, but it is a good test. If you do this, do so offline, see if it helps and reselect "normal startup". The problem will return, but at least you will know it isn't the system itself. (If the problem doesn't go away, you might have a driver conflict)
