I bought a geforce fx5200 a month or so ago... It worked perfectly fine.. even running high performance apps like Sim City 4.. meya and others.. but after i installed the latest drivers fron Nvidia's site. Now my comp freezes anytime I try to run any high end app. Ive tried uninstalling new drivers and installing old(ones from CD i got with the 5200) but to no avail.. any Ideas on what could be causing this?
