Do you have a case speaker? That is the only way you will tell for sure, as said above the LED's are for power being used indication with DES software/hardware

Nothing to do with your error

What ram is this

And have you tried a older GFX card? Sounds like your card may not be putting out a signal but your board is running fine maybe since you are only seeing a few led's on and not all of them as they would be if you were in the bios or any of the boot screens before the system was running
