Computer boot no response need to boot after shutdown and then how to solve the boot

Computer boot, no response.

Computer boot does not respond when the more common computer failure, its causes are many, for the rookie of the computer boot did not respond to the main look when the monitor is not bright, and then understand some of the computer may also go to see the host Power indicator light is not bright, if more understanding of the friend may be the mainframe shell to take apart, look at the internal operation of the host is normal, The main is to see whether the CPU fan is turned, the hard disk is working (you can put the hand on the hard disk surface feel whether there is a disk vibration, if any, the motherboard is running. To solve the computer boot does not respond, the solution is for its possible causes to solve.

Computer boot does not respond to the most obvious is the computer monitor is not bright, so the simplest response is not the reality of the light, found such a problem, we need to do from simple to complex to find the cause, to find the reason to solve the easy. The following is a summary of some computer boot not responding to the reasons and solutions.

⒈ computer boot, no response---monitor problem

Many novice friends encounter computer boot no response, many times are just small problems, such as the display power did not plug well led to no show, many friends do not know it, in addition to the monitor data line and host or monitor at both ends of a bad contact will also lead to computer boot did not respond. In addition, there is a power indicator button on the monitor, if not open, the monitor will not light, natural computer boot did not respond.

Monitor problem caused by computer boot unresponsive solution: first check the display power indicator can be, there is no light, no light, press the monitor power supply key, if the monitor power indicator is still not lit, please check, the monitor power part is normal, if the power is normal, the monitor is still not, most of the monitor itself fault , you need to contact the dealer or repair the solution.

⒉ computer boot does not show-host problem

Computer host caused the computer boot did not respond to the same more common, such as excessive memory dust, poor contact and so are more common reasons. In addition the computer host has the line contact bad and so on also easily causes this kind of problem, is inferior to the hard disk data line contact quantity and so on.

Computer host caused by the boot does not respond, we can eliminate the law to solve, first of all to exclude the display of interference, and then exclude a later to enter this step operation, the solution is generally check the internal wiring of the host is good contact, and then pull out the memory, with clean things to wipe the memory gold fingers, then put up to try it. If it's still not working, check to see if the hard drive is running properly. If the above are excluded, you can consider whether the problem is the computer power supply, because the power supply voltage is low will cause us to see the internal CPU fan in the normal turn, but the reality is no response, etc., the solution can take a multimeter to test the power supply output voltage is normal.

⒊ computer boot, no response----computer hardware failure

DIY computer hardware as part of the computer, their respective hardware are in the state of mutual cooperation, when there is a computer hardware failure, such as the monitor does not work, poor memory, motherboard failures and graphics and other failures are easily caused by computer boot.

Turn it off before you boot

Recently have a network excellent asked such a strange problem, computer boot monitor no display, need to shut down and then reopen before you can, feel very strange. In fact, this type of failure is most likely due to a small computer hardware problems, may be about to go bad. Repeated power may sometimes be lit, such as a common problem with the supply, motherboard BIOS failure and graphics and other failures can be generated, interested friends can go to research.
