MS-6570 motherboard. Version 1.0 K7N2G Has an MSI D-Bracket. LED 1,3,4=RED. LED 2=Green No Post or anything on screen. MB taken out of case and tested with ram, processor and video only. Nothing else attached. 1 x long beep....pause 5 seconds...1 x beep...pause 5 seconds...etc. This is continous. 256mb Ram + Processor all work in another Test PC OK. Nothing from MSI about errors for 1 long beep. My conclusion is a faulty MB.
