Error code 21


My EVGA nForce 680i SLI motherboard is refusing to boot (fans go for a minute or two, then stop), and the LED error code is showing 21, which is a "Init Heuristic Power Management" error.

What do people think, new motherboard or PSU?

  1. This is the sort of reaction I expected... nobody knows!

    Any input would be appreciated though, my best guess is I need a new motherboard.
