Thanks. Went to Device Manager. No yellow exclamation points, so no drivers there that it is indicating it is not happy with.
Any Question Marks? Unknown Devices?
Device Manager has to be happy - to have a stable machine.
Every device has a ‘sandbox’ that it plays in. If a program makes a call to a device, and that device is ‘unknown’ - no ‘sandbox’ in memory is reserved.
Like calling an un-designated phone number ... except the Kernal panics and see’s someone attempting to Read/Write to unreserved space, it throws up an obscure error like “x less than zero” and viola - BSOD.
You have a new Hard drive, memory, processor and motherboard. If you brought your wife’s HDD over PHYSICALLY, you could be having a EROM over-flow issue (disk is going bad, and your drive is out of space in it’s memory to tell the OS that certain sectors are ‘off-limits’).
If you merely brought the OS and files over - then the disk is probably OK. But, despite the obvious lies - when a drive says that MTBF is 1.2 Million hours; that’s a pretty outrageous lie. That’s about 136.9 years.
