Help! I just baught a PNY Nvidia 9800GT 1 gig card for my son gaming computer. I replaced a 7300GT that worked fine. We installed the card and eveything worked good for an hour or so. Now the computer freezes at start-up. It recognizes the card, shows the msi/boot screen, starts Vista (64 bit) with the scolling green Windows symbol then it freezes. It will work in safe mode and when i unistall the driver the computer works fine. Of course, PNY nor Nvidia can support today. ANY Ideas what I could have done wrong?
