      Ram or Video chip/cable

      by brian_meahan – ·

      In reply to Can someone help me with my problem?

      for many bios, 4 short beeps like that is a ram problem. Has it done any memory dumps or anything previously. Since you’re getting nothing on the display it could be the video chip toasted or possible the cable connecting the display. Try hooking it to an external monitor or preferrably to a docking station. Not sure if they will take over video before post is finished (kind of doubt it) but it’s worth a shot. You can try reseating the ram and the video cable connections but be careful as the video cables are often those flat ribbon cables that are easy to break.

      1 long, 3 short: Memory test failure:
      A fault has been detected in memory above 64KB

      1 long, 8 short: Display test failure:

      1) Replace BIOS battery.
      2) Replace memory (update the memory to the maximum the motherboard can take).
      If you can not do it yourself please get someone “in the know” to do it for you.
