Lenovo AM3 Motherboard does not boot how to do

Lenovo AM3 Motherboard does not boot the solution one:

First detect the computer's power environment and the use of the environment is abnormal, such as voltage instability or low temperature. If you can eliminate environmental problems, if you want to solve the problem, I suggest you first open the chassis using a soft brush or air cooler to clean the internal dust, and then observe the motherboard capacitance whether there is a bulge or leakage phenomenon.

After the motherboard appearance problem is removed, disconnect the power cord from the motherboard, use a screwdriver to break the motherboard switch pins to see if the normal power can be added (because the old Heroes machine, switch is mechanical, dust more prone to such problems), if normal, it is recommended that you remove the front panel using alcohol cleaning switch button, stop 30 points around the switch line test. Operation prerequisite must be power off operation to avoid static electricity caused parts damage!

If the above operation is still invalid, I suggest you send to repair station for specific testing, otherwise you can only replace the power gradually test.

Secondly:

First check the hardware has no contact problems, with rubber rub gold finger contact part.

The most common scenario is memory and motherboard problems. Try removing all other hardware and plugging in the memory machine, listen to have no alarm sound, if there is any more alarm sound processing, if not, it should be memory or motherboard problems. Try again with the replacement method. It is only after several rounds of investigation that the problem is to be known.

Generally added memory can not open the machine because the power supply is not enough,

But you put the new, or can not open the machine, may have damaged the memory slot, or burned out a part of the motherboard, may be just,

But first I suggest you borrow a power to try (the power of the larger type), if not, you can tell the situation again

First unplug the memory and then turn the system on. Can hear the alarm sound means the motherboard and CPU are good, can not hear the alarm sound proof that the motherboard and CPU are not working properly. Then try a good power supply. If you still can't hear it, it's probably the motherboard problem!

Lenovo AM3 Motherboard does not boot the solution two:

First check that the computer has started the operating system when it is powered on. If a panic, blue screen, or automatic reboot occurs when the operating system is started, the partition table for the hard disk and the master boot Record are normal, troubleshooting the hard disk partition table corruption, the hard drive master boot record, and the missing hard disk partition end sign. The following method is then used to diagnose.

1th Step: Start the computer in Safe mode first, to see if it can start, if it does not start, it may be infected, System file loss, operating system damage, hard drive, hardware device conflicts or hardware problems, go to step 4th; If you can start Safe mode, it may be that the hardware driver is incompatible with the system, The operating system is problematic or infected with the virus.

2nd step: Then run antivirus software, if there is a virus, it may be caused by virus, anti-virus after the restart of the computer, if not normal, you need to reinstall the operating system.

3rd Step: If the virus is not detected, you can use the operating system with the "System Restore" function, the System Restore, restore if the system is normal, the fault is caused by system damage. If the failure is still the case, the device driver may be incompatible with the system; then the sound card, video card, Nic and other devices to remove the driver, and then install the driver, each installation of a device to restart the computer to check which device driver caused by the fault, check out, Download the new driver for the faulty device and install it.

4th Step: If you cannot start from Safe mode, then reinstall the operating system with the installation CD. If you can install the operating system normally, go 7 steps, if the operating system failure, such as the crash, blue screen, reboot, etc. caused the system can not be installed, it should be a hardware problem or bad hardware contact caused.

The 5th step: Then clean the dust in the computer, cleaning memory, graphics and other equipment, such as gold fingers, reinstall memory and other equipment, and then reinstall the operating system, if the normal installation of systems, it is bad contact caused by the failure.

6th step: If you still cannot install the system, it may be a hardware problem caused by the failure. Then use the replacement method to check the hardware failure, after the replacement of hardware can be found.

7th step: If the operating system can be installed properly, and after installation failure disappears, it is the system file damage caused by the failure.

8th step: If the installation of the operating system, the failure is still, it may be the hard drive has bad road or device driver and system incompatible and so on. Use Safe mode to start the computer, if it can not start, it is hard drive has bad cause of the fault. Then use the NDD disk tool to repair the bad way.

9th step: If you can start Safe mode, the device driver is incompatible with the system. Then the sound card, video card, network card and other devices to remove, and then install the driver one after another, to install a start, to check which device driver caused by the fault. After checking out, download the new driver for the faulty device and install it.
