Kabalo ka bro sa vista daghan incompatibilities so why use that if your system have a problem when using vista. ME I had a bad experience before using win vista 32bit, in the middle of nowhere when playing movies like DVD mo error cya unsupported video driver daw ang prob...so what I did I update or use the latest driver from NVIDIA coz my chipset is from nvidia man so mao karon even using vista di nako mag problema.
Better use XP w/ SP2 not the SP3 k. I hope it helps.
