I know this is going to sound crazy oldschool. I have an HP pavilion a820n. I added windows 7 32 bit(from XP). Now my P.C. wont recognize my graphics adaptor. I think its an intel(r) 82915G/GV/910GL express chipset family. If I install a radeon hd 5450 will it work on my mobo( ptgd1-la goldfish)? All I care to do on it is play Diablo 3 which requires direct x.
