Did the system work fine before and this all of a sudden happened?

My initial thought is bad RAM. Try reseating it. Also try reseating the video card.

If you are using 2x512mb of ram then try each stick individually and see if it helps.

Yes it just happened my computer was working fine in tell i shut it down in the morning then when i turned it back on it started beeping and I've tried reseating my ram and video card and it didn't do anything but i can't try one stick of ram at a time because i have rambus ram and i have to have every ram slot filled for my computer to run

It appears we are not talking about the system in your sig then. I too have a system using the dead Rambus ram technology.

If you pull the memory and power on the system does the beep code change? Check with your video card as well.

Are you set up with all dimms filled with actual RAM or are you also using continuity modules?

Well two beeps is not a valid beep code for the 420. I suggest you check the diagnostic leds in the back of the computer then go here and see what they mean.
