These are the steps back up reps use to troubleshoot motherboard that are "dead". A motherboard is non "dead" if POST beeps are heard. Assuming no beeps are heard, the lath is classified equally dead.

Steps

  1. i

    To diagnose a dead motherboard you beginning need to remove all the DIMMs and cards attached to it. Once you lot have done that, try to ability up the system, and if beeps are heard, and so the motherboard is probably fine and yous have issues with either a PSU or whatever other hardware.

  2. 2

    If it didn't make a beep-like sound, make sure your CPU is correctly attached to the socket, and the speaker is hooked upwardly. Attach the PSU cord to the motherboard and check if the fans fire up. Additionally, you tin can endeavor doing the following

    • Test the voltage
      A motherboard volition not work if at that place is no power getting to it. To exam the voltage, use a multimeter. There should be at least 3.3 volts on the motherboard, but 5 volts is preferable. If the motherboard has an LED, check to run into if it lights upwardly when you plug in the ability supply.
    • Check the PSU
      If the motherboard doesn't have power, cheque the power supply. Make sure that it is plugged in and that the switch is on. Disconnect all of the other components from the ability supply and endeavor to turn it on. If information technology still doesn't work, the ability supply is probably bad.
    • Bug with CPU
      If the motherboard has power only the computer still doesn't plough on, there may be an consequence with the CPU. Make sure that the CPU is properly seated in the socket and that the fan is plugged in. If the CPU is not properly seated, information technology volition not brand contact with the pins in the socket, and the calculator will non turn on.

  3. 3

    Farther Diagnosis. If zilch of the above seems to work, attempt the methods below

      • Check the jumper settings. If the passenger vehicle runs at 100Mhz, 133Mhz, etc. try a slower double-decker speed to meet if that produces a beep. Endeavor the "machine" setting if applicable rather than specifying a item bus speed. Set the multiplier to a slower speed such equally ii.5.
      • Check the voltage settings for Socket seven CPUs.
      • Check the CPU for bent or broken pins or damaged contacts.
      • Reset the CPU. Take the CPU out and reinsert it, making certain information technology seats well.
      • Try another CPU if possible. At this point, we simply want a beep. Information technology is unlikely that the CPU is bad, but if some other one is handy, attempt that to see if a beep is heard.
      • If the board is an ATX design, remove Air-conditioning power from the power supply, unhook the ability supply cable from the lath, reinsert information technology and employ Ac power to the power supply again.
      • At this point, if the system is in a example, take the board out and try information technology on a examination bench setup, anti-static bag on top of instance, etc. to bank check for grounding problems.
      • If possible, endeavour a different Power Supply. Fifty-fifty if the power supply runs and the fan spins, etc. information technology could still have a problem.
      • If the board is yet expressionless, if possible, try some other mainboard. Does information technology work with the same CPU, Power Supply, etc?
      • If none of the above produce a beep, nosotros have hitting a wall. There is little else to attempt to the board may in fact be DOA.

  • Question

    My PC doesn't starting time. I changed the power supply cable. SMPS is working with other systems but does not work on my organization. Is it a motherboard problem?

    Community Answer

    Your motherboard may have been fried. However, it could be other parts that acquired this. Check every role. If yous truly think it is your motherboard, information technology may be time for a new one.

  • Question

    My PC does not stop when I press the ability button. What do I practise?

    Community Answer

    Y'all may take to hold the button down for near ten seconds to force the reckoner off. Of course, you're supposed to utilise the virtual "Turn Off Figurer" button in the operating system, not the hardware push on the front of the reckoner. The operating system (such equally Windows) writes a lot of files to the hard drive when you ask to turn the calculator off, and then information technology powers down. It gets messy if yous strength a power-down without giving the operating organization a gamble to write those files.

  • Question

    My PC isn't booting. The small calorie-free on the motherboard is glowing and then I don't recollect the SMPS is faulty. I think the motherboard is fired or the BIOS chip is corrupted. What should I do?

    Community Answer

    It might be the power supply. There are kicking-up fault readers - a trivial troubleshooting board you tin can plug into a PCI slot or somewhere else on your motherboard. t will confirm if all the voltages are in range and stable, and tin also make up one's mind if other devices are faulty. Like, fifty-fifty if a CPU fan froze upward, the reckoner won't boot. These mistake-reading devices wink codes, and include a cheat-sail for you to await upwardly what the code ways.

  • Question

    My PC will not first. SMPS is working with other systems, but when I connect that SMPS to my organization it does not offset. Also, I checked another SMPS with my arrangement and it will not work. Is it a motherboard problem, or what?

    Community Answer

    It could exist your motherboard. I also faced this problem running Windows 7 and Intel Pentium dual cadre, I replaced the motherboard and it is working fine at present! I suggest you check your motherboard.

  • Question

    My PC won't boot after two hours of attempted restarts. Is this a motherboard issue?

    Community Answer

    My bets are on the ability supply. Effort a computer troubleshooting aid. Search Newegg or Amazon for PC test kits or diagnostic cards. These troubleshooting cards can read out codes to tell you what the problem is.

  • Question

    How do I test a motherboard without a CPU or RAM?

    Community Answer

    There is no proper style of checking a motherboard without a CPU and RAM, just you can partially check using a diagnostic bill of fare.

  • Question

    My CPU fan is running and the hard drive LED is blinking, but at that place is no point on the monitor. Also, there is no beep on starting. What can I do?

    Community Answer

    Remove all components except power supply and little beep speaker. Plough on the power and see if you get a single beep from the MB. If so, MB is working. If not, problem is PS or MB, and a PS swap out is necessary to bank check. Powering off and on with each, add one RAM stick at a time using slots recommended in the manual or just trying them all, and then other components 1 at a fourth dimension. Any time you neglect to get a beep, the terminal element y'all added is the trouble. If a machine has been working fine and suddenly won't boot, xc% of the time I observe it's the RAM - either bad or improperly seated. Due to abiding heating and cooling, RAM chips tend to work loose from contacts, or just plain go bad.

  • If the motherboard is producing beeps from the speaker, almost certainly one of the following is true:

    • The memory is non seen, incompatible with the board, running likewise fast, etc. - long beeps that repeat forever. In this state of affairs, effort another DIMM if possible, lower the motorbus speed to see if the memory works, try the DIMM in a dissimilar memory socket.
    • The video carte du jour is not in all the mode - especially mutual with AGP cards - or the video card has a compatibility problem long beep followed past some short beeps. Brand certain the video menu is in all the manner, endeavor a different video carte if possible to cheque for a compatibility problem.

Thank you for submitting a tip for review!

  • Follow instructions very carefully. Working with estimator hardware is catchy and can have some unforgivable consequences.

  • If you are not comfy doing this, don't.
