Ok so i knocked a glass of vodka over my laptop in a drunken stupor and now it doesn't work. that was my primary computer, so now i'm working with a crappy hand me down desktop. it's a dell optiplex 170L, and i'm looking to get a graphics card for it for s-video out because it just has an integrated graphics chip atm, but i don't know how to figure out which type it supports(agp,pci,pci-e)? is there a way i can tell just by looking at it, because i don't have an owners manual or anything. thanks for the help in advance.
