Many PC users often face a problem when loading windows 7 hangs on the logo, i.e. loading normally goes to a certain place, after which operating system (OS) falls into a “stupor” and is reduced to “feelings” only after pressing the Reset button.
There are many reasons that lead to this phenomenon, among which there are 5 most common. Let's consider them in more detail.
We work with BIOS settings
The current tab can also be changed when the laptop is turned off. Just switch the slider to the desired value - endurance or speed, and the system will go to the desired setting. He buys himself with much more power and even more laptop power.
The multimedia laptop is primarily intended as a highly mobile professional workstation, but still offers a very decent multimedia standard. Optical drive I had no problems with the environment in the tests and did a good job with old disks.
Possible causes and solutions
- virus programs are the main cause of fatal changes in the "OS";
You need to use modern anti-virus scanners to help detect and remove malware and spyware from your PC. If the antivirus did not help, manually terminate the suspicious processes in the registry and in the autoload, then find and delete all the suspicious files from the hard drive.
Sound playback comes from two small stereo speakers located above the keyboard. However, they cannot be ashamed of their performance, and laptops with a much larger chassis are also calm. The built-in camera, located at the top of the thin screen, can be considered an additional standard. However, he is rich enough to organize video conferencing. A microphone is integrated right next to the display frame.
Cooling and working noise Air is drawn in at the bottom of the device, while exhalation is concentrated on the back. The advantage of this solution is that the user is not bothered by warm air, as if the exhaust fan was on the side of the laptop.
- oS start stop may occur during banal overheating of the processor and chipset;
A failed cooler, an old thermal grease, a radiator clogged with dust, can stop the PC in a matter of minutes. When the system boots, you need to use one of the many utilities to check the temperature of the central processor, video card, chipset.
Cooling is very effective, and the laptop case does not appear even after prolonged use and a high load on signs of overheating. Neither the keyboard nor the touchpad have a noticeably higher temperature at any point on their surface, which reduces the comfort of work. The bottom of the device heats up, but there are no unpleasant temperatures, so the laptop can easily work on your lap.
Noise is also very low. Cooling is heard only in a quiet room, and when you use your laptop at home or in the office, you can hardly hear it. However, the noise level only drops and returns to its original level immediately after unloading. Battery The battery is located on the back of the device. There are two sliders, one of which has a lock function and a second fuse function. The battery can be easily removed. However, the imperfect mating described above, which causes a tendency to oscillate in place, has frozen.
If the cause is overheating, and the cooling functions, but is clogged with dust, then it is necessary to clean the PC using compressed air or a vacuum cleaner.
- problems with rAM memory also often lead to unplanned stops when starting Widows 7;
Among the malfunctions, RAM most often occurs, overheating and a defect, due to damage to the memory module. Unfortunately, the latter type of problem can only be detected by testing.
The recommendation of specialists: when overheating, use special heat sinks that significantly reduce the risk of failure of RAM. If this does not help, replace the device. A factory defect in the RAM module may “surface” even after prolonged use of the memory.
- falling into the “stupor” of the PC when starting the “OS” is often due to mechanical, electronic, logical or hardware-software failures in the hard drive;
You can detect problems in the hard drive through testing by running the utility in Widows 7 or using third-party software. Extraneous sounds often become harbingers of the problems of the "screw". If you see strange noise and clicks in the "hard" you need to do backup its contents and be ready to purchase a new device.
- sometimes, the reason for the "braking" of the computer during the initialization of devices is incorrect settings or an outdated version of the BIOS;
Most often, this happens after installing new components on the old motherboard. BIOS may simply not have information about them. The solution in this case is quite simple: initially return to the factory settings or update the BIOS.
Sometimes you can solve the problem of PC freezing at startup, rollback to control pointthat the system creates.
To do this, you must have boot disk and perform a few simple steps:
- reboot the PC and go into the BIOS. Depending on the manufacturer, the input keys may be different, most often it is Del; F2; Esc. In order to accurately determine the enter key, you need to refer to the documents that come with the system board;
- change the download priority. To do this, go to the BOOT section, after which you need to go to the Boot Device Priority menu item;
- select the 1st Boot Device item and confirm by pressing Enter. In the appeared Option window, select the drive and press Enter. After this procedure, the PC will be launched from this device;
- exit this menu, then press Esc, then Exit, after Enter, and then confirm the save settings with Enter;
- insert into the CDROM a disk with an “OS” or a boot disk and reboot;
Configure the registry to detect a freeze problem
In order to surely identify which process leads to a halt in OS startup, a small adjustment should be made in the registry entries.
You can do this by booting with support command lineby entering the command: regedit.exe.
- in the left part of the window that opens, select the KEY_LOCAL_MACHINE folder, after that, open SOFTWARE, find and open Microsoft in this directory, and then Windows;
In this directory, you need to find and open CurrentVersion, then Policies and finally the System;
- having opened the System directory, pay attention to the right side of the window;
In it you need to find the Verbose Status file. Open it and the tab that opens, set the value to 1; (The default value is 0)
Important! You should be aware that the desired file in the registry may not be. In this case, it must be created. Click on free space on the right side of the window, select the Create menu item, and then the DWORD Parameter (32 bits). Name the created file VerboseStatus with a value of 1.
- after that the registry can be closed and rebooted;
As a result, when you start the OS, you will see the loaded services and processes of the system. On what it will stall - and is the cause of all ills.

We work with BIOS settings
The shutdown procedure often helps to get rid of the “machine” freezing at boot: often - but not always. Sometimes BIOS settings play a decisive role, changes of which almost always lead to PC freezing.
What you should pay attention to:
Panacea - reset to factory settings.
Deactivate Devices
Suppose, according to the report, the system went into hibernation when loading the CLASSPNP.SYS driver.
In order to find out which device this driver is responsible for, you can try to disable the PC components in the BIOS one by one:
Having found a component that causes Widows 7 to hang on the logo when it boots, you can install a discrete device in the expansion slot on the motherboard.
Important! In the case of replacing the device, the PC may not load the “OS”, displaying error information on the monitor screen. To fix this, go back to the I / O system, go to the Halt On tab, and select No Errors. On the Halt On Errors tab, set the value to None. Now the PC will boot even with an error.
Reset to factory settings
You can reset the parameters to “factory” in several ways, the most common of which are:
- zeroing directly from BIOS;
- by removing the battery from the system board;
In the first case, you should go into the BIOS and select the Load Fail-Safe Defaults option. After which, answer in the affirmative the question of resetting the parameters and save the changes. After an automatic reboot, the changes will take effect.
The second, easiest way:
- disconnect the PC;
- remove the cover from the computer system unit;
- remove the battery from the motherboard;
- after 15-30 seconds, insert the battery into place;
Thus, the parameters will be set by default, i.e. factory.

Install the new version of BIOS
In some cases, the BIOS may not provide proper support for all components of the computer due to an outdated version of the firmware.
This leads to their incorrect operation and braking Windows 7 at startup:
Important! During the update procedure, do not turn off the power of the PC. This can lead to malfunction of the motherboard.
The methods described by us allow us to effectively solve the problem of computer freezing at startup. If you think that the above methods are not suitable for you, or the PC’s performance has not been restored, then be sure to contact the service center, where professionals will solve the problem.
