Ok you guys have been wonderful to me in the past. Now i'm back with probably a stupid question. I have to upgrade my power supply before I can install a new graphics card. Found a nice 450 watt thing. Says it's SATA supported. I have googled the *%$# for sata vs. IDE. I have an IDE. ( i should have bought an apple), Never did i think i would have to spend so much time just trying to update my darned computer. IF i don't have SATA on my system, and i have no idea how to tell except i ran a check and everything says IDE on it, will i fry my mother board? Please dumb it down. thanks. Cherie
