The computer will not start to solve

There are a variety of reasons why computers cannot be started. First we need to figure out whether the hardware or software is causing the problem.

The specific resolution steps are as follows:

1, check all cables (including power plugs) to ensure that all equipment is correct and tightly connected together.

2, check whether the power is turned on. Listen to the sound of the power supply fan and whether the hard drive is working properly. If you don't hear anything, you may need to replace the power device. To determine this, consider using a power test device, such as PC power and cooling, to test the output to ensure that there is no problem with the circuit.

3, if the power supply is normal, but the screen is still a dark, try to connect the computer to another monitor to determine the problem is not a monitor. If the monitor is working properly, do you have a video connection cable to look at, or no image? If the hard drive works at this point, it is likely that the video card has failed. To replace the new motherboard, or use the motherboard's consolidated video card, if the motherboard has this feature. When the chassis is open, check that all fans are running properly after the power is started, and the computer may also encounter overheating problems.

4, if your monitor is working properly, but the hard drive does not start and the display does not have any images (or you can see the image but the computer can not start by self-test), consider reinstalling the CMOS. Turn off the computer, unplug the power, then wear anti-static protective gloves, and remove the battery from the motherboard. Then wait about five minutes, check your PC user manual or visit the manufacturer's website for information on how to reset the CMOS settings and restart the computer to see if the problem is resolved.

5, if the computer is still unable to start, the culprit may be broken memory. Remove one memory at a time (or replace it with known normal memory) and reboot after each replacement. In addition, you can create a free MemTest86 boot disk on another computer and use it to select a memory bar.

6, if the above methods are not effective, it is possible that the motherboard or CPU is broken, need to be replaced however at this time the data on the computer may still be intact, as long as the hard drive connected to other PC host, you can take out the data. Consider going to a computer repair shop to get someone to fix the computer, which is better than a new computer. If you are using a laptop, the repair shop may be your best and only option.
