There are a wide variety of reasons why the computer may not be turned on or not loaded and, as a rule, on external features, which will be tamed below, it is possible to determine this cause with a certain share of confidence. More often, problems are caused by software failures or missing files, recordings on the hard disk, less often faults with a hardware component of the computer.
In any case, whatever happens, remember: even if "nothing works", most likely everything will be fine: your data will remain on the spot, and the PC or laptop is easy enough to return to the working condition.
We will get ready to consider common options in order.
The monitor or computer does not turn on, but it shows the black screen and does not load
Very often, referring to the repair of the computer, users themselves diagnose their problem as follows: the computer turns on, but the monitor does not work. It should be noted here that most often they are mistaken and the reason is still in the computer: the fact that he is noise, and the indicators are burning at all means it works. In more detail about this in the articles:- The computer does not boot, only noise, showing the black screen
- The monitor does not turn on
After turning on the computer immediately turns off
The causes of such behavior may differ, but usually they are associated with the fault of the power supply or overheating of the computer. If, after turning on the PC, it turns off before the Windows boot starts, then, most likely, it is in the power supply and, possibly, it requires replacement.
If the automatic shutdown from the computer occurs after a while after its operation, then there is already more likely overheating and most likely, it is enough to clean the computer from dust and replace the thermal champion:

When you turn on the computer writes an error
You turned on the computer, but instead of downloading Windows you saw an error message? Most likely, a problem with any system files, with the order of loading in BIOS or with similar things. As a rule, quite easily corrected. Here is the list of the most common problems of this kind (by reference - description how to solve the problem):- Bootmgr is missing - how to fix the error
- NTLDR Is Missing.
- Hal.dll error
- Non System Disk Or Disk Error (about this error I have not yet written. The first thing you should try to do is disable all the flash drives and pull out all the discs, check the download order in the BIOS and try to turn on the computer).
- Kernel32.dll not found

I press the power button, but nothing happens
If after you have pressed the on / off button, but nothing happened: the fans did not earn, the LEDs did not catch fire, then first of all you need to check the following things:- Connecting to the power supply network.
- Whether the network filter is enabled and the switch on the computer power supply is rear (for desktop PC).
- Whether all wires are fully stuck where necessary.
- There is electricity in the apartment.
If with all this order, then you should check the computer power supply. Ideally - try to connect another, a guaranteed working, but this is a topic of a separate article. If you do not feel a specialist in this, I would advise calling the masters.
Windows 7 does not start
Another article that may also be useful and in which various options are listed that allow you to correct the problem when the Windows 7 operating system does not start.Summarizing
I hope someone will help the listed materials. And I, in turn, concluded this sample, I realized that the topic was associated with problems expressing in the inability to include a computer, I was not very good. There is something else to add than and do it in the near future.
