If those 0x101 BSODs were being caused by a faulty CPU you will see them again, even with Windows in that pristine state. That's what you're checking for.
I've done all of the above & everything appears to be OK.
Would it be OK for me now to proceed uploading my software? Or is there something else that needs doing first?
Should I upload the software bit-bit, & keep making System Restore Points, just in case there is a problem with the software? I should add that I would not be adding to the laptop any software I am not already running on the laptop I am using to communicate here - & that is running fine.
