  • System Hangs At Startup

    I have a small server running Windows 2003 R2 SP2.
    During a system reboot the OS did not load and just hanged while attempting to load. I assumed it was a crashed HD or something, but wanted to test this so I tried to boot from a Windows 2003 CD and could not boot. The system hangs before I can even enter BIOS.

    I thought it might be some BIOS/software problem so I cleared CMOS, but that did not resolve the problem.

    I thing it might be a failed hardware, but not sure how to diagnose. I don't think its the HD since I can't even boot from a CD.

    Also, another symptom is that sometimes when I try to start the monitor doesn't even show anything...as if it is not receiving signal.

    If someone has encountered this problem or can adivse on how to diagnose, it would be greatly appreciated.

    I think its either the mobo or the CPU.

    Could Be:

    - Power Supply
    - RAM
    - Hard Disk
    - Graphics Card
    - Loose Electricity In The Motherboard
    - System Software Corruption

    Also, do you hear Beeps? And the red light infront of the case (The processing light), do you see it stuck and always turned on?

      action plan:
      1. disconnect all external devices
      2. bring system to minimal config, enough to complete POST:
      - motherboatd, 1 CPU, 1 VRM (if applicable), 1 memory DIMM (on some systems 2 DIMMs, because a channel has to be full), risers (if applicable).
      everything else - hard drives, CD drives, PCI cards, TBUs, DAS - all have to be disconnected
      3. if system completes POST at the minimal config, telling you it cannot boot into the OS (because the drives are removed) - start adding devices back into the server, try to detect which one causes the issue.
      4. if system still doesn?t POST, it might be the MB/CPU/risers/Memory
      CPUs can be tested by trying another one in the slot, same with the DIMMs
      risers can be reseated or replaced. MB can only be replaced.

        Re: System Hangs At Startup

        John2008, I do not hear any system beeps and the system light does not stay on.

        Dyasny, I unplugged everything and the only thing I have attached to the motherboard is the CPU, RAM, and video card....the system does not post and the screen is blank. It seems like the monitor is not receiving signal from the motherboard.

        My other previously mentioned symptom, the screen is completely blank, is becoming more frequent. It seems that eveytime I try to boot the system, even with minimal config. just for POST, the monitor is always blank and is not receiving signal from the mobo.

        I took the video-card out of the PCI-E slot and placed it back in, just in case it has become loose over time...the problem still exists.

        Note: Here is NY because of all the Air Conditioners running during the summer, our local electric company has been reducing power to the point where almost no electrical devices can run because there is not enough juice. On more than one occasion, the server simply turned off and made a winding down noise. Is it possible this could have messed something up?

        On my way to get a new video card and test. Will report back as soon as I try.

          Re: System Hangs At Startup

          what kind of server has a videocard?

          anyhow, get a UPS for that, if the power grid is found lacking.
          also, try with another monitor, might be simply a bad screen.
          have a look at the mobo, if you see any blown up capacitors, replace it.

          no beep codes available, I presume?

            Problem: System starts but screen is blank. THe monitor is not receiving signal. One in a while it might receive signal but hangs right before entering POST; hangs right before I can press DEL to enter BIOS.

            Monitor: It is OK because I replaced it with a working monitor. Also, during one of the boots I got as far as the screen right before pressing DEL, which sends me into BIOS. However, like old times it froze there before even entering POST.

            VideoCard: Not the problem because I went and got a different video card.

            Motherboard: No blow capacitors, but it still could be the culprit.

            Reconnected everything from the power supply to make sure there is no false
            connections.

            NO system beeps.

            What is going on?

              Re: System Hangs At Startup

              If you tried this:

              - Changing the RAM with a working one.
              - Changing the VGA Card with a working one.
              - Changing the Power Supply with a working one.
              - Changing the Hard Disk with a working one.
              - Chnaging the Monitor with a working one.

              If you are sure that:
              - The cables are in a good conditions.

              And It's still not working, so I have to say 2 words: Motherboard + Electricity
              I had this problem before, and I tried all above, and it was a loose electricity In the motherboard.

              I suggest you send it to a computing electronical specialist, or check the electricity yourself using the electricity device checker to find the loose.

                Re: System Hangs At Startup

                Have you tried moving the server somewhere else with better mains to test, or at least the UPS recommended by DYasny.
                Also I see you said you reset the bios, did you try unplugging all power and then removing the battery as well just ito give that a go?
                cheers

                  Re: System Hangs At Startup

                  John2008, I changed everything except the motherboard, CPU, and power supply.

                  AndyJG247, I did unplug the powers and removed the battery.

                  I assumed it was either the motherboard or the CPU ( twice, about 1 month ago, I unsuccessfully tried to overclock the CPU....that might be a factor).

                  Then we've had the power problems I described below from our local electric company.

                  I thought I had it narrowed down to Mobo and CPU.
                  How does the PSU fit it, how does the PSU break?

                  Given the above info, how you you rank the likelyhood of each piece being the problem. I have it as:
                  1) CPU 50%
                  2) Mobo 40%
                  3) PSU 10%

                    You didn't change the "Power Supply"? Many of the problems just like yours, is happening because of the "Power Supply". I think you should try to change it first, it doesn't cost much, rather than going deeper with "CPU" and "Motherboard".

                      Re: System Hangs At Startup

                      This is what i would do.

                      1. Remove eveything from the system except the CPU and try booting. If you have the system speaker you should at least hear system beeps signifying no RAM. If you don't hear anything then there is something wrong with either the motherboard or CPU.

                      2. Add ram and you should hopefully hear beeps signifying no Graphics Card. (Can only be done if Graphics Card is NOT on-board.)

                      Do the fans run when you start the server??? Open the case and look at the CPU fan.

                      No fans probably means a duff Power Supply. You can check these using a multi-meter.

                      Try the first step and see if you get beep codes though.

                      BTW what type of server is it??

                        Re: System Hangs At Startup

                        Wullieb1. I followed your instructions. When I booted with only CPU I did hear a non-stopping system beep...I guess indicating there is no RAM. Then, I inserted the RAM but I did not hear a system beep indicating no video-card. That is odd since the mobo doesn't have its own graphics-card. The problem can't be the video-card because I tried a different, brand-new video card.

                        The tower is completely open as I try to diagnose this problem, and I see the fans spinning during boot.

                        Server: Windows 2003 R2 SP3

                        John2008, I'm looking into PSU because the one I have is LOUD and only 550W. By the way, is 550W enough if i have:
                        4 HDs
                        4 RAM sticks
                        Videocard with its own Power supply
                        2 optical drives
                        3 120mm FANS

                          So you don't hear any beeps with the missing graphics card???

                          I would personally say that your motherboard and CPU are working at least to a point anyway.

                          Have you tried a PCI or AGP card in the machine?? I'm presuming its a PCI-e graphics card you have installed. It could be that the PCI-e slot is faulty.

                            Yes, the mobo doesn't been when I take the video card out even though the mobo doesn't have a built in video-card. That's wierd!
                            Also, I tried a different video card and that did not work either...so I don't see how it could be the video card.

                            The original video card is PCIE16.
                            The other one I tried was just regular PCI.

                            If the PCI slots are broken, then won't I need to change the mobo?

                              Have you tested the voltages on your PSU yet???

                              My opinion would be that your motherboard is only getting part way thru post and is goosed. If it NEEDS a GC as you're suggesting then it will beep when it doesn't have one installed.

                              The only true way to test it though is to get a known good board and test your CPU in that then test a known good CPU in your board.
