We probably can get this fixed, but I have two questons.
First, I read the entire thread, again, quickly, I did not see a mention of System Restore, if not used, go back a week before the problem started and then see if it works.
On page 2 of this opus, my third post, I mention that I had done a restore back to 2 weeks before the problems. No joy. In fact I started with a restore point the day before the problems, and continued to work backward. When I reached two weeks, I quit.
Second: If necessary, how do you feel about going back to factory specs, the way it was the day you bought the computer. No progarms etc. As far as updates, you only have to install the 3 SP and a few updates that were not included in the SP
The above is the recovery drive.
I do have most everything backed on an external hard drive.
