I had installed the NFS Most Wanted. It was working fine. Last Sunday I had to reinstall XP because a problem in a HDD (with stripping RAID!) All data lost! Luck I had a back-up! . System was an MSI K8N Neo-FSR, BIOS 1.7, drivers 5.11, Athlon 64 2800, MSI RX9800PRO with Catalyst 5.11, and on board audio with Realtek A3.81 drivers. The same day I sold the Radeon so I bought an XFX 6600GT PCI Express to use with an MSI K8N Neo3-F I got in RMA a month ago. Dirvers are 6.70 for the mother and 81.98 for the VGA. Now when I start the game, the HDD seems to do something for a second, and then nothing happens. Even inserting the DVD and starting with the splash menu, the same happens and after a few seconds, the menu shuts down! I changed drivers for the recomended ones, don't remember # but it was the one that says in the readme, changed the audio drivers for the Realtek ones, but is the same. The demo is working fine. Any advices will be wellcome!! Thanks in advance!!
