Help the computer does not turn on
Good day everyone! The problem was carrying a computer with me from the Far East in a container, at minus 40 it drove all over Siberia! the paste is dry, can the thermal paste freeze out!? (the computer was driving in frost for a month) all the lights are on, everything is spinning, it cools, but the computer does not start !? can the computer not work without thermal paste !?You explain it incomprehensibly, your computer starts up but the monitor has a black screen?
When you start the computer, there should be a beeping sound, I don't have it, a black screen, the computer does not start
check the power supply. Without thermal paste, the computer will start (I don’t know how long it will work, but it will start). What specific bulbs are on?
And how to make a bios, or how to check? Before the county there was a Windows, on two screws, and there and there! I always had one like this just in case
I had a similar situevena (the current of the computer was not in the cold), the capacitors were blown up and the fans were spinning too, but the computer did not start, so check the power supply first. if you don't know how to bring it to the service.
You can't do a BIOS in any way, it's a microcircuit soldered on the board, so if it's dead, then it's only the service center that will help you.

Reset the BIOS, and see if any LEDs on the motherboard are on.
what is your fee? BIOS is reset either by a switch on the board, or by jumpering the jumpers on the board. usually these are three pins, two of which are closed with a special jumper, you need to rearrange the jumper so that it closes the one that is not closed, press the computer's power button and hold it for a couple of seconds, and then put the jumper in place. all this is usually located next to the battery that is on the board.
check what? if the power supply unit (as I understand it, you do not really cut it in this) then the masters

There is no opportunity to check a computer with some components from a friend?
Maxim Nepomniachtchi, take him
to a specialist. you yourself will not have enough gray matter. There they will definitely do it for you, and you will do it yourself.

It is impossible to expose such a technique to severe frosts. From a very low temperature in a PC, literally everything can deteriorate, from conduits to optics in drives. Also, do not forget about moisture and condensation.
It is not difficult to check the power supply unit: we shorten the green and black wires. Next, we measure the voltage based on the pinout (google for help). But no matter how I would rely 100% on such a check. Nevertheless, serious problems are thus identified 100%
there may not be a sound if the speaker is dead, but it will not hurt to start,
you said correctly, bring it to a specialist
if you don’t want to
make sure that the power supply unit is working (the fan or something should react even in the power supply unit)
pull out the memory the computer loves to swear and scream when there is no memory))
turn on the mother percent, if something is spinning something like that, but the power supply works, then if the screw is turned on, listen to it rustling if it can be dead. if it rustles, then there is food for it too.
also on many mothers there is an LED inside that works when there is some kind of voltage,
disconnect the video and insert it again, often when shaking it can partially move away if there is a wretched old one plug it in and see what is on the screen
it is also important that the monitor reacts at least somehow to turning on the computer, it can go into safe mode and refuse to start the monitor (the light on the monica either blinks or burns orange, red) the
computer will start even if you pull out the video card (the percent and the screw are spinning) may even beep ...
next to the battery on the motherboard there are jumpers that are usually responsible for resetting all BIOS parameters and next to the motherboard itself on the board it is written how to put the jumper (also try to start without a battery)
if the keyboard is usable or wireless, then it often does not react at start until the drivers will be loaded, but this does not mean that the keyboard does not work or is broken (you just need a ps2 adapter for yusb) or an old keyboard for 100 rubles
