Sabertooth X58 - No Video

Hi all,

I've had my computer put together and running with no issues for about 2 years. It has a GTX580 on a Sabertooth X58 and 6gigs of ram. Last night I forgot to turn it off before I went to bed and found it powered on but with no video signal to the monitor. I assumed it had fallen asleep, and tried various things to wake it up, to no avail. I then did a hard reboot and that's when the problem presented itself.

I opened it up, reseated everything, and then turned it on again. Here is what happens.

Mem Red LED briefly turns on, then turns off (should indicate there is no memory problem).

PCI-E Red LED briefly turns on, then turns off (should indicate no problem with PCI-E slots). There is one long beep as this light turns off.

Boot Device red LED turns on for a bit longer than the others, then there are 2 beeps, then it turns off. Then the computer just stays running until I turn it off, but the video never comes on.

I've tried reseating things again, and resetting the CMOS (I was worried that something got screwed up with the boot order since that light was on the longest), but nothing seems to be helping. Any suggestions on where to go from here?

  1. Hi, Try removing all components but CPU and CPU fan.
    Start the board - 1 long 2 short
    Insert only one RAM stick - start the board - 1 long, 3 short
    Install graphics card - 1 short, 1 short
  2. Thanks, just want to add one more data point before I try what you recommended. My computer had been unplugged and powered down for about 40 minutes and my roomate suggested I try hooked it up to his peripherals. I did so, still heard the 1 long beep 2 short beeps but then I did get a video signal. He only has VGA on his monitor though so had to use an adaptor on my video card since it only has DVI out. While the colors looked a bit off on his screen, it did fully boot.

    Does this potentially indicate my graphics card is in the process of dying?
  3. It might be. Does your graphics card work in his PC?

    Ok Alex,

    I did as you suggested and I got the exact pattern of beeps you described, which is especially interesting because before I was getting 1 short, followed by 2 short, and now I'm getting the 1 short, 1 short you predicted. Does this indicate what to do next?


    Update: I went ahead and reconnected the keyboard to see if that would elminate one beep. It did. I now just get 1 short beep when it turns on and then nothing else. But I'm still not seeing any video.

    Yes, connect only DVD drive, keyboard and mouse. Use the USB 2.0 ports.
    Start the board and it should... POST.
    Insert a bootable DVD drive and see if it does boot from it.

    Update: Try then the graphics card in your friend's PC. You'll know for sure if it's a card issue.
  6. And I'm up and running. I wonder what caused everything to go wrong. Video seems completely fine now. Is there anything I can do to determine what caused it to have this issue today?

    Thanks again!
  7. No, AFAIK.
    A voltage variation, a component getting old... hard to say.
    What you can try next time (if happening again) is unplugging the power cord and pressing the power button for about 30 seconds. This would drain the residual power.
  8. What is the PSU's brand/model ?
