1. No idea, but maybe these will help.
But if the computer is working fine then I guess it's ok, though the beep code kinda makes me worry.
2. Thats your mobo giving you a beep code. Check the mobo manufacturers website or the mobo manual for the meaning of that beep code. Though did this start right after installing the new ram? If so then it pretty much has to be something about the ram.
But check the website/manual to be sure.
