Im having some trouble getting the display to come up on my new build. This is my first time building a new computer and I seem to have run into a roadblock. I have attached all the components together without any issues, but nothing comes onto the display when I try to power it up. I double and triple checked to make sure the GPU was securely in its slot. If anyone can give me an idea of what im doing wrong, your help is much appreciated. I figured that I should at least get something to come on the display, even if a component was attached wrong or not attached at all. pleeeeeze help......I'm dying to get this thing running.

  1. after a bit more research....apparently I should be using the 8-pin connector on my MOBO instead of the 24-pin. I thought the 24-pin was the main power supply for the board? Do I use both connectors?
  2. There should be a 2x4 and 2x12? Based on what I am looking at there is one by the memory(2x12) and one by the external ports (2x4). You should connect both. THe connectors are compatible with 2x2 and 2x10 as well if your PS has those.

    To quote their manual on this:
    "The power connectors are compatible with power supplies with 2x2 12V and 2x10 power connectors. When using a power supply providing a 2x4 12V and a 2x12 power connector, remove the protective covers from the 12V power connector and the main power connector on the motherboard. Do not insert the power supply cables into pins under the protective covers when using a power supply providing a 2x2 12V and a 2x10 power connector."
  3. ok........I got to the post screen. both connectors needed to be plugged in. talk about a rookie mistake. This build is great!! Is it strange to think of a system as being sexy?? lol

    ok.....on to the next graphics card says its supported by various types of windows. (ex. XP, Vista, &) Does that mean that it wont run properly under linux? I am leaning towards ubuntu or fedora.
