Can we have his system specs? Specifically CPU [specific model name, not just 'Pentium'], graphics card [again specifics, not just 'Geforce' and the RAM amount] and the RAM amount.
Run dxdiag and tell us the CPU and RAM from the first tab and the graphics card from the Display tab, please.
e.g. mine is:
CPU: Core 2 Duo E6400
Graphics: Radeon X1950 Pro
RAM: 2GB DDR2
