To some, my question will seem stupid and met with OMG, but you have to start somewhere. Here goes, as I am just learning about computers, I need as much help as possible. I have an old emachine W3118 desktop, that has a 1.80GH AMD Sempron processor,with 2GB installed memory (maxed),PCI express & an 80 GB hard drive. It’s video is integrated. I would like to up grade to a nividia GE Force 8400, 512 MB, DDR2 graphics card. My problem is that I have never done an upgrade from an integrated > graphics card upgrade before. I also cannot seem to find any technical information about the emachine W3118. If anyone would be willing to write me up a wlak through or at least point me in the right direction I would deeply appreciate it.
