For example, if a driver writes information to a memory area that's allocated to another driver - there may not be any problem(s) at that time.
Then, if the first driver exits, there's no record of it having written to the other driver's area.
Then, when the other driver tries to get some information from that area, it finds that the correct stuff isn't there. It then panics and crashes with a BSOD.
The BSOD has no information about the first driver...

Then, when the other driver tries to get some information from that area, it finds that the correct stuff isn't there. It then panics and crashes with a BSOD.
The BSOD has no information about the first driver (which actually caused the error) because it exited before the crash occurred.
