New system problem. Continuous beep on startup.

Hi, I recently put together a homebuilt system after reading the Tom's Hardware forums to learn about how to do it and what kind of components to use.

I have a problem now whenever I start it because instead of booting properly, all I get is a long continuous beep that doesn't stop and there is nothing that shows up on the screen. I think the problem may be with the video card, since I tried to remove it and successfully got the system to boot and could get into BIOS. Even when I have the video card in and it doesn't work, all the fans spin, including the video card fan. I will post what components I used. Please let me know if any of you have had a similar problem or if you have any ideas on how I could get it fixed.

Here is the video card. I couldn't add it to the wish list because it's not available now.

  2. Are there any things I can look for to see if the video card is not installed properly or if it's faulty?
  3. Make sure it's seated fully. And did you connect the two 6-pin connectors?

    Ok so I checked the link for your 5850, is that really an 8pin and a 6pin connector? I was under the assumption that most 5850s use two (2) 6-pin connectors only. Does it come with some sort of cable converter because it doesn't seem like it in the picture.
  4. Thanks for looking into it fastx21! The video card has 2 separate power connectors, a 6pin and an 8pin. My PSU came with cables that allow me to either plug in a 6pin or an 8 pin. (There is a 6pin and a 2pin that can be either inserted together for 8pin or just use the 6pin alone.)

    I tried connecting the video card with the 8pin connector first, and later tried with the 6pin and both times I had the same resulting continuous beep on startup.

    I never even thought of connecting both 6pin and 8pin connectors. I guess I assumed it was one or the other. Could connecting both damage it if it isn't designed to have both connected?
  5. Wow, I plugged both the 8 and 6 pin connectors in and now it works. I feel so silly for making such a simple mistake, but the instructions were a little vague and I just assumed that the video card would only need one plug like everything else.

    I was almost reaching a point of despair. Thanks for your reply, it was very helpful. As I pressed the power button and heard no annoying long beep, I was so relieved and happy.

    Thanks again fastx21!
  6. Just to say thanks ran into the same problem and was able to find the answer here.
    go figure, tom's works better as an faq than asus website.

    thanks again.
