These are the steps support reps use to troubleshoot motherboard that are "expressionless". A motherboard is not "dead" if POST beeps are heard. Assuming no beeps are heard, the lath is classified equally dead.

Steps

  1. 1

    To diagnose a dead motherboard you first need to remove all the DIMMs and cards attached to it. Once you lot have done that, try to power up the arrangement, and if beeps are heard, then the motherboard is probably fine and you take issues with either a PSU or any other hardware.

  2. 2

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

    • Exam the voltage
      A motherboard will not work if in that location is no power getting to it. To test the voltage, use a multimeter. There should be at least three.iii volts on the motherboard, just 5 volts is preferable. If the motherboard has an LED, check to see if it lights upward when you plug in the ability supply.
    • Check the PSU
      If the motherboard doesn't have power, check the power supply. Make certain that information technology is plugged in and that the switch is on. Disconnect all of the other components from the power supply and try to plough it on. If it yet doesn't work, the power supply is probably bad.
    • Issues with CPU
      If the motherboard has power only the computer all the same doesn't turn on, at that place may be an issue with the CPU. Brand sure that the CPU is properly seated in the socket and that the fan is plugged in. If the CPU is non properly seated, it volition not make contact with the pins in the socket, and the computer volition not turn on.

    Advertizing

  3. 3

    Further Diagnosis. If nothing of the above seems to work, try the methods below

      • Bank check the jumper settings. If the coach runs at 100Mhz, 133Mhz, etc. try a slower omnibus speed to meet if that produces a beep. Try the "auto" setting if applicable rather than specifying a particular double-decker speed. Gear up the multiplier to a slower speed such as two.5.
      • Bank check the voltage settings for Socket 7 CPUs.
      • Check the CPU for bent or cleaved pins or damaged contacts.
      • Reset the CPU. Accept the CPU out and reinsert it, making certain it seats well.
      • Endeavor another CPU if possible. At this point, we just want a beep. It is unlikely that the CPU is bad, but if another one is handy, try that to see if a beep is heard.
      • If the board is an ATX design, remove AC ability from the power supply, unhook the power supply cable from the board, reinsert it and utilize Ac power to the power supply once more.
      • At this point, if the system is in a case, take the board out and attempt it on a exam demote setup, anti-static handbag on top of case, etc. to cheque for grounding issues.
      • If possible, try a unlike Power Supply. Even if the power supply runs and the fan spins, etc. information technology could nevertheless have a trouble.
      • If the lath is still dead, if possible, try another mainboard. Does it work with the same CPU, Power Supply, etc?
      • If none of the above produce a beep, we have hit a wall. There is fiddling else to try to the board may in fact be DOA.

Add together New Question

  • Question

    My PC doesn't first. I changed the power supply cable. SMPS is working with other systems just does not work on my system. Is it a motherboard trouble?

    Community Answer

    Your motherboard may have been fried. Still, it could exist other parts that caused this. Check every part. If you lot truly remember it is your motherboard, information technology may be fourth dimension for a new one.

  • Question

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

    Community Answer

    You may have to concord the button downward for about 10 seconds to force the figurer off. Of class, you're supposed to apply the virtual "Plough Off Figurer" button in the operating system, not the hardware button on the forepart of the computer. The operating system (such every bit Windows) writes a lot of files to the hard drive when you inquire to turn the computer off, and and so it powers down. It gets messy if y'all force a power-downwardly without giving the operating system a run a risk to write those files.

  • Question

    My PC isn't booting. The small low-cal on the motherboard is glowing so I don't think the SMPS is faulty. I think the motherboard is fired or the BIOS chip is corrupted. What should I exercise?

    Community Answer

    It might be the ability supply. In that location are boot-upwardly error readers - a petty troubleshooting board you 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 can also make up one's mind if other devices are faulty. Like, even if a CPU fan froze upward, the estimator won't boot. These fault-reading devices flash codes, and include a crook-sheet for you to wait upwardly what the lawmaking means.

  • Question

    My PC will not start. SMPS is working with other systems, but when I connect that SMPS to my system it does not commencement. Also, I checked some other SMPS with my system and it will non work. Is it a motherboard trouble, or what?

    Community Answer

    It could exist your motherboard. I also faced this problem running Windows 7 and Intel Pentium dual core, I replaced the motherboard and it is working fine now! 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 power supply. Try a computer troubleshooting aid. Search Newegg or Amazon for PC exam kits or diagnostic cards. These troubleshooting cards can read out codes to tell you what the problem is.

  • Question

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

    Community Answer

    There is no proper way of checking a motherboard without a CPU and RAM, but you can partially check using a diagnostic card.

  • Question

    My CPU fan is running and the hard bulldoze LED is blinking, but there is no bespeak on the monitor. Also, in that location is no beep on starting. What tin can I do?

    Community Answer

    Remove all components except power supply and little beep speaker. Turn on the ability and run into if you get a unmarried beep from the MB. If and then, MB is working. If not, problem is PS or MB, and a PS swap out is necessary to check. Powering off and on with each, add together one RAM stick at a time using slots recommended in the manual or just trying them all, then other components i at a time. Whatsoever time you fail to go a beep, the last element you added is the problem. If a machine has been working fine and of a sudden won't boot, 90% of the fourth dimension I notice it's the RAM - either bad or improperly seated. Due to constant heating and cooling, RAM chips tend to work loose from contacts, or just plain get bad.

  • If the motherboard is producing beeps from the speaker, almost certainly ane of the post-obit is true:

    • The memory is non seen, incompatible with the board, running too fast, etc. - long beeps that echo forever. In this state of affairs, try another DIMM if possible, lower the bus speed to see if the memory works, try the DIMM in a dissimilar retentivity socket.
    • The video card is not in all the style - specially common with AGP cards - or the video card has a compatibility trouble long beep followed by some short beeps. Make certain the video bill of fare is in all the fashion, try a dissimilar video card if possible to cheque for a compatibility trouble.

Thank you for submitting a tip for review!

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

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