I have some problems understanding.
Your computer has no problems starting up, yet it keeps beeping or
your computer has problems booting up and it keeps beeping?
If it's the first situation, it has to do with the Linksys Network
Monitor program. When programs run into memory errors, they often
produce beeps.
If it's the second problem, then I'm not too sure. Linksys doesn't
give much on this issue.
