Simple Tips to Solve Motherboard Problems

Troubleshooting the Motherboard

motherboardIf the system crashes repeatedly, it is possible due to motherboard failure. However actual motherboard failure is rare. It is possible that some other problems like loose connections, power failure or overheating may cause system failure.

  1. Turn off the system and remove the power cord.
  2. Check connections on the motherboard.
  3. If you have made any changes to the BIOS settings, restore them to the default value.
  4. Ensure that the motherboard is not touching the system case or the drive tray.
  5. Check whether there are any cross connections between wires.
  6. Wear an anti static wristband.
  7. Place the removed components on antistatic package.

Instability in a new system:

A newly assembled system may show problems like frequent error messages and problems while starting up. These problems can be caused by a variety of reasons like loose connections or incorrect settings.  Some of the problems may also be caused due to motherboard.

  1. Check all connections and cables on the motherboard. The connections must be tight and placed properly.
  2. Ensure that the motherboard with the CPU, video card and the memory is properly connected to the power supply.
  3. Check the system temperature and ensure that the heat sink and fan are working properly.
  4. Check if the power supply is loaded with more devices and components than it can handle. If you have upgraded your system or added a device, the power supply must be able to handle it.
  5. The system memory may have failed. Check the system memory and ensure it is connected and configured properly. Also check if the memory is compatible with the motherboard.
  6. Check the jumper settings on the motherboard. Inspect the CPU for any problems.
  7. Check the BIOS settings and ensure if they are correct. If possible set them as default.
  8. Inspect the expansion cards on the motherboard for proper correction or configuration.
  9. Ensure that the hard disk drives have proper jumper settings.
  10. Check the IRQ settings of the system for any conflicts that can arise during system assembly or addition of new hardware.
  11. If your cache is corrupt or incompatible, it may lead to motherboard problems. Disable cache in BIOS. If the system works properly, then the cache was faulty.
  12. If the system does not work properly, check whether the cache is properly installed.

 System does not start though fans are working:

In some cases, you may not be able to access drives and the video may also not work. If the system does not start up, but the system fans work fine, it is mostly either a motherboard or CPU problem.

  1. Remove the CPU and reseat the Motherboard.
  2. Check the seating of the CPU on the motherboard and ensure that it is locked down.
  3. Ensure that the motherboard power supply is properly connected.
  4. Check all the ribbon cables to see that they are connected to the appropriate drives and they are oriented properly.
  5. Reset the BIOS settings to default. Try the safe booting procedures with power up defaults by referring to the motherboard manual.
  6. If the system does not start up, the memory, CPU or the motherboard are faulty.
  7. Remove any additional memory and try starting with minimum memory. Then swap the memory and try starting the system. If the system starts with either of the memories than the other memory is faulty.
  8. Check all jumpers and connections on the motherboard. Check the motherboard expansion slots for metal fragments.
  9. Replace the CPU on the motherboard, if the system works the CPU is faulty.
  10. If the system does not work with the new CPU, try placing the CPU on another motherboard. If it works then, your motherboard is faulty.

When switched ON, the system only beeps or shows POST error:

  1. Check post messages and correct the problem if possible.
  2. Check for perfect connection of socketed chips such as memory modules, BIOS or keyboard controller, CPU etc.
  3. Temporarily remove the network cards and other PCI cards from the motherboard.
  4. If the problem is solved then replace cards one by one and each time check for where actually fault lies.
  5. Remove and reset all essential expansion cards and check the interconnecting cables.
  6. If the system does not function than replace the Motherboard.
