What to do when the computer reboots by itself

A computer is an integral part of modernity, without which a very large number of people can not imagine life without it. And such situations, when the computer reboots itself, can pretty badly damage your nerves to any person. After all, many people know the situation when everything seems to be working stably, you are doing your own business and then the monitor turns off and the sound of the fan is heard to the ears, informing you that a reboot has occurred. Unfortunately, such situations are not uncommon. If the computer reboots by itself, then it's worth starting to look for the problem immediately and do not put it off for a long time.

So, with what can spontaneous reboots be connected? If the computer reboots itself on windows 7 or under the control of other operating systems, then there may be a lot of possible reasons. Let's start with the most common:

It is likely that the computer reboots are due to a lack of power installed power supply, or in cases where its functionality can be questioned. Especially often this happens at the moment of computer upgrade , when users joyfully carry a brand new video card from the store, install it, and the power of the power supply unit is quite a bit short to ensure stable operation. In these situations it is possible that the computer reboots by itself, although more often, it simply will not start.

In addition, there is a possibility that somewhere inside our "box" some contacts have departed. The place of detachment can not even be seen. This is especially common with memory. In such a situation, the signal coming from the processor may not reach the place of the lost contact, which causes the computer to reboot itself. In such cases it is necessary to carefully check that all the components were tightly installed in the corresponding slots and not "dangled" in them.

In addition to problems with the equipment, a software problem is very likely. In order to get rid of them, it is desirable to get the system restore points made earlier and roll it back to an earlier version. It is recommended to remove all software installed from the time the reboots started. In extreme cases, you can try completely to reinstall the operating system, and if that does not help, then format the hard drive, before making backup copies of all important files. If this does not help and the computer reboots by itself, then it's probably in the hardware.

To find the problem, you can use various utilities that will test the RAM, as well as the hard drive. Also, if several RAM slots are installed in the computer, you can alternately pull them out and start the computer, waiting for the result. It is likely that the reboot is due to a failed hard drive that is currently running at its last gasp and in a very short time will refuse to run at all. To exclude this, it is recommended to get an unnecessary hard disk (maybe an old 40 gigabyte screw was lying around) and test the system directly with it. It is not superfluous to reset the BIOS settings either by entering it directly before starting the system or by removing the battery from the motherboard (the reset time is different, depending on the motherboard and varies in the range of 3x10 minutes).

To avoid reloading, due to the fault of power surges, it is recommended to buy an uninterruptible power supply. It will save all unsaved documents and avoid unnecessary hassle, which occurs when the computer reboots by itself.
