Editing Nvidia Pascal GPU Diagnosing Guide (section)

=== Power sequence ===
The order in which they turn on in most pascal GPUs is as follows: '''5V→ 1.8V→ VCore→ VMem/PEX.'''

For example, if 5v does not turn on, everything else in the chain won't turn on either. Hence no fan spin if you have a problem with 5V or 1.8V.

If you're missing one of them, check their respective page:
