My Dell XPS M140's display finally gave out on me. In about the last month or two, I was getting error messages pointing toward the graphics direction. I am in process of getting a display for it if I can find one since I know without a doubt it is bad. I am working with Dell and a place here in town, as well as looking online myself. I'm hoping the red flags were caused by the bad display, but if not, then it is more than likely the graphics card, which is soldered onto the motherboard. I figure if the motherboard is junk because of the graphics card, I might as well try to replace the graphics card first since it can't hurt anything. If it is possible, I'd like to get an NVIDIA graphics card. I have experience soldering small circuits and feel confident I can put the new card on myself if I have to. Can this be done by a professional? What are the steps to doing something like this? Will I have to download the drivers for said graphics card first, then attempt to replace the card?
