Error code 21 Tags: Chipsets Motherboards LED Monitor Last response: December 5, 2010 12:10 PM in Motherboards Share The_Kangaroo December 5, 2010 7:59:03 AM Hi, 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? Cheers, Kanga. More about : error code The_Kangaroo December 5, 2010 12:10:28 PM 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. Can't find your answer ? Ask !
