my platform bases on e5-2697v2 and w2600cr .
couples of days ago it cannot be powered on , beeps 1-5-4-2 , which means dc failure .
this goes on with or without board battery .
i think my power cases are running normally , so the mainboard is to be replaced .
but thing is that w2600cr is discontinued 2years ago , so that is the question .
please help !!!
