The computer reboots itself, overheats
Posted: Wed Jan 29, 2025 7:03 am
One of the common problems in the operation of a computer is its spontaneous reboot or shutdown, usually accompanied by a system freeze and general instability of its operation, twitching, and slowdown in the execution of various applications.
This also happens when playing computer games; during the game, various defects, stripes, glare, etc. may appear on the image, after which the computer freezes and reboots, or the user has to reboot the computer himself.
But there is usually only one reason for this: the computer components overheat (video card, central processor), which causes the computer to spontaneously reboot and the overall instability of the system to appear.
This problem is easy to solve, for this we open the side cover of the computer and see if all the coolers (these are small fans in the computer) are spinning when the computer is on, there may also be obvious thermal damage to the coolers, they have melted, if you find a faulty cooler, then carefully remove it, you can do it together with the radiator, and replace it with another one, you can buy them in any computer. If all the coolers are working properly, then you may need to clean the computer from dust.
To do this, you can use a vacuum cleaner or a viber data small brush, just be careful not to touch any parts, just move the vacuum cleaner a few millimeters from the computer components, pay special attention to the fans, thoroughly clean them from dust, also unscrew the CPU cooler from the radiator and clean the radiator separately. Do not forget to clean the cooler on the video card.
If after cleaning the computer from dust the situation has not improved, then listen to the operation of the coolers; if they rattle, make a lot of noise or practically do not rotate (this can be determined by eye), then you will have to replace them.
It could also be much more prosaic and the computer overheats because it is close to the heating battery, which is why it cannot cope with self-cooling. Just move the computer a little further away, and the problem may disappear.
Specifics of CPU coolers
For each processor model, depending on its socket, a specific cooler model is required, for example, if you have Socket 775, then you need to buy a cooler for Socket 775, to find out the model of your socket, look at the motherboard, usually it is written in bold, for example Socket AM2 or Socket 775, etc.
Specifics of replacing coolers on the central processor
(Please note that all actions are performed with the computer turned off and not otherwise) The fastening of the cooler and radiator depends on the model of the cooler you purchased. They are fastened with simple latches of various types or screwed with bolts into a pre-installed substrate under the motherboard.
I advise you not to buy the whole radiator + cooler set, as the price is higher and replacement is more difficult, it is better to unscrew the fan itself from the radiator, there are four bolts on it, one bolt per corner, unscrew them, having previously disconnected the cooler power cable from the motherboard, press the latch and pull out the cable, take the cooler with you to the store to find the same one.
If you still decide to change the cooler together with the radiator, then do the following: Press the latches or unscrew the bolts that secure the radiator to the processor and remove them. You may have to apply a little force since there is thermal paste between the radiator and the cooler and it has glued them together a little, but do not pull too hard. You may have simply not pressed all the latches or not completely unscrewed the bolts.
Wipe the old thermal paste off the processor with a cloth and apply a thin layer of new thermal paste evenly over the entire surface of the processor. If thermal paste gets outside the processor onto the motherboard, remove it with a cloth. (The paste usually comes with a new cooler (a small tube). If you did not find one in the kit, you can buy it separately at any computer store.) After applying the thermal paste, carefully install the radiator with the cooler and secure it with latches or bolts, depending on your mount.
The specifics of coolers on a video card - here things are simpler, there are no specifics, we just remove the cooler, take it to the store and buy a new one of the appropriate size.
