Usually the long series of beeps does indicate a RAM problem, having just had a problem with a PC not POSTing myself (different story, but was a cooked capacitor on the Mobo and got absolutely nothing), I have run through all the steps myself.
You have two sticks of RAM - which DIMM slots have you inserted them into? If the K8NS is anything like my shiny new K8NSC-939, the Memory will only work if both DIMMs are either in Slots 1 and 2; or 3 and 4 only. They won't work if you have them set up in as an example 1 and 3; or 2 and 3, they won't work.
If you've only got 3 slots, then you might have to put both sticks into the same channel (my old Albatron Socket A had 3 slots, and you had to either put 1Gb into slots 1, and leave the others empty, or put in 512Mb into slot 1 and share 256Mb into slots 2 and 3, because slots 2 and 3 were considered one channel and slot 1 was another). Of course it may well be different because of the two different companies.
The other problem could possibly be a complete incompatability of the RAM with the system - that used to happen to me when I sent my machines to the local shop for new RAM, computer would come back and either refuse to work or shutdown in a hail storm of Blue screens... Then I joined the darkside and built computers myself!
Apart from that you could also seek advice from
www.techsupportforums.com as that place is full of people who I think build CPUs and Operating Systems for !!!!!s and giggles in their spare time...
