Computer can not start, the monitor does not show, the host did not alarm sound, power, CPU, graphics cards, fans are transferred, the hard disk is also transferred. Unplug the memory, boot is the same, no sound. Is the motherboard broken or memory failure?
Elder brother, you say a method, if good, everybody happy. If it's not good, send the maintenance... If it's in the Qingdao development zone... Can come to me; memory card to take down. There is a button on the main board, the battery is round, and the one dollar coin is so big. Take it down. Unplug the main box power line, hold the start button for 15 seconds, then release. Restore all parts to boot... Well do not send good maintenance. The rest of you can't do it yourself. You don't have any tools.... Good luck to you, bye.
The computer can not start, the monitor does not show, the host does not alarm sound, instructions:1, now there is no power, probably the power cord connected to the power supply is bad, or power socket problems.2, if not the computer power line damage itself, the power is likely to damage judgment method, remove the power supply power, connect the blue line board plug and the ground, if the power supply fan rotation, the supply basically no problem.3, may also be a part of the power load, short-circuit, resulting in the power itself protection. The removal method can solve the problem by using the replacement method to detect the short circuit parts.4, if not peripheral parts, may be the motherboard itself problems. Finally, if the other components are removed, try replacing the motherboard!5, if the fault still, then unplug the Power switch and Reset line on the motherboard and other switches, light connection, and then short-circuit switch with a screwdriver to see whether it can boot.6, if you can not boot, then use the minimum system method, the data line of hard disk, floppy drive, CD-ROM pulled out, and then check whether the computer can boot, if the computer displays the boot screen, the problem in these devices. Then, each of these devices is connected to the computer one by one, when access to a device, the failure to reproduce, indicating that the fault is caused by this device, and finally focus on the inspection of this device.7, if the fault is still, then the failure may be caused by memory, graphics cards, CPU, motherboards and other equipment. Then, the memory, video card, CPU and other devices are checked by using the plug and play method and the switching method respectively
The board should be the problem, I do not know what type of board you are. Now the board has a fault indicator light, if it is the boss, then use the test card to try, and 00 is the motherboard fault.
