Question:

Computer motherboard connected power supply did not respond to how to do?

Computer motherboard connected power supply did not respond to how to do?

Answer:

No response can boot the computer starting from these aspects: 1, check whether the power button failure: open the box, unplug the power button connection, using tweezers or screwdriver short boot terminal (boot key original connected copper generally labeled as Power On or Power SW, PSON, PWRBTN, M/BSW). If you can turn on (fan rotation), indicating that the power button failure, if not turn on (fan rotation), indicating the power button without trouble. 2, the host power supply: Unplug the connection line whether power supply and main power supply interface board (large), the two row in the 4, 5 (black and green) with wire or wire short circuit at the power supply fan does not turn (such as 12V voltage meter can measure the voltage of each color and black electric wire the line is not in line with the voltage on the power supply box marked with the power value, no fault, does not comply with the power supply damage). If the switch shows that the power supply can work, if not turn on the power supply damage. 3, remove the dust inside the box: Unplug the power, unplug all boards, remove the CPU, remove the motherboard, completely remove the dust inside the chassis.
Motherboard discharge: Unplug all power, unplug the motherboard battery, short, clear the CMOS jumper (two or three pins, generally marked with CMOS CLEAR) 3 to 7 seconds. Then put the batteries on.
Hardware reset installation: install CPU, motherboard power interface, small horn to connect the power test machine (board to plug in, CPU and radiator coated with heat conductive silica gel). If there is a small horn alarm sound fault has been ruled out, if the trumpet no alarm sound CPU or motherboard (the motherboard does not power on fault phenomenon has many problems such as: CPU power supply module, circuit board and so on) basically have to repair.
If it is contained in the motherboard memory, graphics card (if it is not explicitly set), CPU, under the condition that the power supply is no reaction, the best method is to replace the power supply method, respectively, the memory card, each one by one replacement, replacing a part once a machine, troubleshooting, is not clear you said the board is new or old, as if the old board, one by one after the replacement are still not open, it is the motherboard problem. I hope my method will help you
With the upstairs said, if you have a little bit of foundation it is better to send the computer repair shop, because of the change in the parts you have, the possibility to change a lot, the fittings are measured, you can conclude that you are the problem!
