Stef’s laptop is now sitting on the kitchen table, a few feet away from me. It is working perfectly! When it was picked-up by Helaine yesterday it was running at 100% CPU usage 100% of the time.
This is much too strange.
When I shut it down a moment ago to run McAfee (required and provided by her school and set to keep out other virus protection) in Safe Mode, a program with a cryptic name hung. It was on the shutdown cycle–to brief to write down the name. It looked like “app.” followed by a long and random string of letters.
But, again, at the moment it’s running fine. Maybe I just haven’t found the trigger that starts the process?
Oh–speaking of McAfee, why does it diligently spot and mark cookies? They are marked as “Potentially Unwanted Program.” My suspicion is this is a way the program can always find something!
Thanks to all who’ve sent recommendations. Most have or had been done. I’ve been troubleshooting PCs forever. All the obvious tricks have been played.
