Just a passing note/question.
This is a long thread so I am just double checking that you have run memtest and driver verifier to eliminate RAM as the issue and to try and identify if a particular driver is at fault.
Have you?
How many un-powered USB devices do you have attached to this computer?
Hi - thanks for helping out. It's a long thread b/c I'm not particularly conversant with fixing things myself so you'll have to bear with me.
I do not currently have any USB devices attached. The only time I do is to plug a flashdrive in or my external hard drive to back up the laptop. Usually there is nothing plugged in which makes the notices puzzling.
I have not done a memtest. If that involves taking out modules, I have no idea how to do that. Way beyond my knowledge set.
As for a driver verifier - I'm not sure if I've done that one. What is it called? It doesn't sound familiar.
Sorry, as I mentioned, I'm not that great with this stuff.
