owners of personal computers, which has never seen a black screen when booting the operating system, can be considered a real lucky.Who found the heyday of Windows 9x line, no doubt, remember the blue screen of death or BSODy (from the English. BSOD - Blue Screen of Dead), which seemed to arise for no reason.However, over the years of the "running" Microsoft has collected enough statistics to decide on the transfer of all of its systems products to a promising nucleus of NT.After that, the frequency of occurrence BSODov dropped significantly.However, there is another problem - a black screen.During a terrible name hides a logical behavior of the operating system, in which due to a further error loading key files, and makes it impossible to stop at the intermediate stage.As a result, the forming image software module is inoperative and no pictures - the user sees a black screen.
give an example.After pressing the power button on the screen, there are the usual BIOS messages and self-test passes.It would seem - even 20 seconds and you can start to work with the applications Windows.Alas, the familiar logo Microsoft products, you can not see, as the monitor black screen.Waiting for hours - the picture appears.An important point - the LED monitor power light is not flashing, symbolizing the transition sleep mode, and even burns.
Such behavior suggests a computer software component failure.Very often, this happens when the thoughtless use of various applications-optimizers.You can try to recover, although the guarantee of success no one will.
Black Screen Windows 7, the "symptoms" of which we have described above can be "cured" in the following ways:
- immediately after the self-test should be frequently BIOS to press F8.If the stop error occurs after the state inquiry keystrokes (usually it is), then the screen in text mode displays a list of possible actions.You must select the "Last Known Good Configuration";
- start to boot from a disk with the distribution of the operating system, and at one stage, following the prompts, select "Restore."Troubleshooting Wizard will scan your system for errors and try to fix them.This method is suitable for the "failures" of the file system and boot sector.
Sometimes the answer to the question of why, when you start the computer black screen is very simple.As a rule, all modern BIOS configured to work with hard drives in a mode AHCI, since it allows you to fully exploit the potential of drives and controllers.If for some reason the BIOS settings slipping into standard, where the disk subsystem is registered mode IDE, the system load is no longer possible due to the mismatch of the active module and the exposed motherboard regime.Such a failure could occur when updating (flashing) BIOS, resetting due shrunken battery and reset jumper after use.By the way, the opposite is true: IDE installed in the operating system will not boot in AHCI.
course, a black screen may be explained by several reasons.But it's the themes of other articles.
