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.
No Question marks or yellow Exclamation points in Device Manager, thanks.
