But then you need to show exactly what you're doing.  The following  
works for me:

\documentclass{book}
\usepackage{amsmath,amsthm}
\theoremstyle{plain}
\newtheorem{theorem}{Theorem}[chapter]
\usepackage{chngcntr}
\counterwithout{theorem}{chapter}
\renewcommand{\thetheorem}{\Roman{chapter}.\arabic{theorem}}

\begin{document}
\chapter{A chap}
\section{A section}

\begin{theorem}
\[ \pi
\]
\end{theorem}

\chapter{Another chap}
\begin{theorem}
\[
\pi^{2}
\]
\end{theorem}
\end{document}
