Surely many laptop owners have encountered such a problem when the laptop freezes when turned on. The reasons why this happens are different, for example, a malfunction in the software part of the system or a technical malfunction. In today's article, we will consider the most common causes that cause freezes, and also tell you how to deal with them.
Dust and dirt
The first most common reason a laptop freezes when it is turned on is to accumulate too much dust and debris inside the case. Many users mistakenly believe that laptops do not suffer from pollution, but this is not at all. Dust gets inside at every moment convenient for it, gradually it becomes more and more. As a result, the motherboard begins to overheat, the cooling system does not cope with the load, and the laptop simply freezes after strong brakes.
It’s not difficult to fix the problem. It is enough to arm yourself with a screwdriver of the right size and disassemble the laptop in order to completely remove dust. If there is fear that something will be broken or damaged during the disassembly process, then the laptop can be returned to the nearest computer service, where experienced people will quickly disassemble it, clean it and assemble it back.
Bad RAM
The second reason the laptop freezes when it is turned on is a faulty RAM module. This is very common, and there is no way to avoid this damage. The fact is that when assembling a laptop at the factory, the manufacturer pre-purchases RAM from a particular company. The cheaper the device, the greater the likelihood that it has a memory bar from some mediocre company.
But not only this can be the cause of RAM malfunction. There is such a thing as marriage. Even with trusted DDR manufacturers, during the manufacture of RAM strips, some kind of malfunction may occur, as a result of which the entire batch will be defective.
The problem is eliminated by simply replacing the faulty module with a new one, but before you do this, you need to make sure that the matter is in RAM. To do this, remove the plastic cover from the bottom, which covers the memory slots. Next, you should remove the DDR bracket, insert another module in its place and try to turn on the laptop. If two RAM slots are installed, then you need to remove them one at a time, because only 1 module can be faulty.
In general, at home it is still difficult to diagnose a RAM malfunction, since you need to have not only an extra memory bar on your hands, but also a second laptop, so it is best to take the device to a repair service.
HDD failure
Another fairly common reason why a laptop freezes when it is turned on is a hard drive crash. Sometimes the HDD can fail completely imperceptibly for the user. For example, the laptop worked all day, it was turned off at night, and the next morning he ordered a long life. Why this happens is hard to say. Overheating, constant disk load by many processes in the system, production defects, or simply a low-quality product can contribute to this.
Diagnosing a hard drive for a malfunction is easy enough. As a rule, if a laptop freezes after turning on the splash screen of the company logo, and after that nothing happens, then with a high degree of probability the problem is in the HDD. In order to be sure of this, you need to try to start the laptop in safe mode. If all else fails, then the diagnosis is correct.
Also, for diagnostics, you can remove the HDD from the laptop and connect it to the motherboard on a desktop computer. If it is not detected in the system or if it fails to open it through the conductor, then you can safely write off the component for replacement.
System failure
A failure in the operating system also often leads to the fact that the laptop freezes after turning on. The cause of crashes is usually incorrect shutdowns, sudden reboots, accidental deletion of the desired file, Windows update “curves”, etc.
You can fix this problem by restoring the system through safe mode or the original Windows image on disk. Below is a detailed video on how to do all this.
Viral infection
Infection with viruses also often leads to the fact that the laptop freezes when it is turned on. What to do in this case? Fight viruses and eliminate them. The easiest way is to restore the system through safe mode. If this does not help, then it is definitely worth using a special set of utilities that work from under DOS. One of the best is Dr. Web LiveCD. All you need to do is download the utility from the official website, then, following the instructions, write it to a USB flash drive or disk, then insert it into the drive or USB port of the laptop and start it.
Static electricity
Static electricity can also cause freezes. Here, for example, you can often meet users on the network who complain that their Lenovo laptops freeze when they turn on. This problem is especially common on the 500th series of laptops from this manufacturer. What's happening? The laptop hangs tightly on the Lenovo splash screen and does not want to boot any further.
You can fix the problem as follows. You need to remove the battery, and then press the power button and hold it for 1 minute. After that, the battery can be inserted back and the device turned on. In some cases, in addition to the battery, you also have to remove the bottom cover and additionally disconnect the hard drive and drive.
