Motherboard repairing guide
Computer troubleshooting guide
Almost 50% of the computer problems arise due to faulty cabling and internal loose connections between the hardware and the mainboard. Be sure that microprocessor, memory modules, and adapters such as video card are inserted correctly and didn't "pop-up" due to loose connection.
- System is not starting up
1. Check if the main power cable is loose 2. Check if the power is coming to the mainboard (You can check this by a multimeter--- just check on the switch on pin of the front panel of the board.) 3. If the power is not coming to the mainboard, change the SMPS.
- Power lines are OK but still not starting up
Take your motherboard to any local repairing expert.
- System running properly but no display
1. Power off the system and remove the power cable from the main system ( just for precaution) 2. Remove all the memory module(s) from the slot. 3. Rub the pin connectors of the RAM with an eraser. 4. Clear all the RAM slots with a hard brush (soft brush will not clear the inside dust properly) 5. Now start your computer without installing any RAM and hear if your computer is giving any beep sound. 6. If any beep sound is coming from the system then switch off the system and install just a single RAM (if you have more than one RAM) in any slot and start the computer. 7. If your computer is not giving any sound now then the RAM is ok. 8. If still no display appears, remove the RAM from the slot and insert it in another slot (Generally there are more than one ram slot in every motherboard). 9. Still no display????? ..... don't get frustrated. Replace the RAM and check it again. Almost 50% no display problems appear due to RAM problem. The last option is to take your motherboard to local service center.
- System getting overheated and shutting down improperly
1. Remove the motherboard from the cabinet ( I hope you have some basic hardware knowledge : ) 2. Remove the CPU fan carefully from the motherboard. (Do not remove the processor) 3. You might see heavy dust inside the fan and the heatsink which is preventing the air to cool the CPU. 4. Wash out the fan and heat sink properly and reinstall it. Now replace the motherboard and start it.
- No system overheat but computer shutting down after every few minuets
1. Carefully inspect the motherboard visually. You might find out some leaky or faulty capacitors which may look like "popping up from the top". Replacing such faulty caps might solve the problems. 2. This part is a bit tricky and must do carefully------ Start up the computer and try to sense if any ic or component is overheating. Be careful, you may not want the board to get shorted. If such thing happens.... well there is only place to repair it. Your nearest service center : )
