Motherboard:Asus M5A78L-M LX
Processor- AMD phenom II
2 sticks of ram 4 gigs each.
650 Watt Nuetron Power Supply

I have tried pluginng in three keyboards at the same time on every single USB slot available on my Mobo and Case. I have tried removing each ram stick and booting but still get the same keyboard error. The speaker on the Mobo lets out one long beep followed by four short beeps. My Mobo has a slot that fits PS/2 keyboards and I'm buying one today to see if that would make any difference. Any suggestions or anyone ever go through this?

The one long and two short were discussed recently it is a video fault, if you on board pull the video card.  If you do not have a card not sure about where to go.
