Need for Speed Racing Games

Hello,

My Problem ism when i try to play NFS - MW, the game works fine in Quick race mode but when i play in career mode, the problem begins.
when i play in career mode the game works fine till i loose to razor and Sergent Cross take to to Police Station, when MIA gets me to get a new car from garage, as soon as i buy the car the game crashes. i love the game, please can anyone advice how to fix this as My PC is not at fault here cause the game crashes at the exact same point everytime.

PC Config:
C2D E7400 @2.8 GHZ
2 GB RAM (1333 Mhz)
128 MB Graphic (Onboard)
Operating System : win xp 2002 SP 2
i installed 1.3 patch

Thanks in advance

i think the problem is with teh garage and the safe house, i installed a save game of 100% races, the races work fine but as soon as i enter garage or safehouse the game crashes.
