You are not very Clear about the error although you say there is a Beep you dont Mention if the System Passes the POST.
Here is some Interpretations of what i believe might be the Problem..'
If you having 3 Long Beeps Please replace Keyboard or make sure Keyboard is inserted Correctly.
If you receiving repeated Long Beeps it might be Memory Errors-Please see if memory is seeted Correctly otherwise RePlace Memory Modules one for one -Keep in Mind that Memory Works in pairs for these Servers.
