sorry, I can not reproduce your results:
In[1]:= 1+1
$Version
$ReleaseNumber
AbsoluteTiming[Integrate[x^3/(Exp[x]-1),{x,0,Infinity}]]
Out[1]= 2
Out[2]= 8.0 for Microsoft Windows (64-bit) (February 23, 2011)
Out[3]= 1
Out[4]= {1.6692030,\[Pi]^4/15}
and similar results under Linux
maybe a clean reinstall (uninstall Mathematica, reboot, install Mathematica) might help?
