I got my computer a little over a year ago, and I bought an EVGA FX52000 Ultra 128mb and it was not compatible with my PC. I am using a 400w Allied ATx4000p4 power supply with an AMD 2700/333 Athlon XP processor on a MSI NF2 IGP K7N2G-L motherboard. Did that graphics card not run on my PC because of the power supply? I am going to purchase a MSI nVIDIA GeForce 6600GT Video Card 128MB AGP, and I was curious if it would run on my PC? I still have the same motherboard, processor, and power supply.
