The computer does not turn on after going into hibernation, what should I do?

Question

Iron

My computer is relatively new, about a year old, and automatically goes into sleep mode (hibernation) after about an hour if I'm not using it. It turns off and the power button starts flashing continuously, I often have it in hibernation or sleep mode (after turning it on, all that remains is to enter the password and continue to use it). There were no problems and brakes except for a strange behavior when turned on (starting, then turning off, then abruptly starting without pressing, etc.), as well as unexpected turning on of the fans at night for a few seconds (without turning on the screen) and abruptly turning them off after a couple of dozen seconds or a couple of minutes. Yesterday I also left it on, after which the computer went to sleep as usual. After 2-3 hours I tried to turn on the computer: the fans turned on and immediately turned off. And so the cycle an infinite number of times, the computer did not turn on, the motherboard did not start, nothing beeped. I disconnected the power / plugged the wires, it did not help. I googled that supposedly the power supply goes into protection. According to the instructions, by turning off the vidyuhi and a couple of screws, this turning on of the fans increased from half a second to 2 seconds, after which it immediately turned off, and when I turned off absolutely everything (the last one was the RAM) except the motherboard, the power supply started the computer and the valves themselves did not stop. Deciding that the RAM was to blame, I connected everything back except for it, but in the end everything is the same: the fans turn off after half a second and so on in a cycle. Further, according to the instructions, I disconnected the largest cable from the motherboard and closed the green and black wires with a pin: the unit started up properly at full power (the cooling started working very loudly), while there was total resistance except for the RAM. Next, I connected the cable back to the motherboard, and after I put the RAM bar in another slot, the unit stopped starting the computer even for half a second, when you press it, there is no reaction, the blades do not spin, and the second time when you close it with a pin, it didn’t start, although when you connected the power ultrasound is heard (it was immediately after the purchase of the computer, if the computer is turned off but there is power to the unit, you can hear a thin, barely noticeable squeak like ultrasound). The block appears to be in excellent condition. a thin, barely noticeable squeak is heard, like ultrasound).

What about the computer? Block burnt out? How? Why after falling into a dream from which he never came out? There was no load on the computer, I turn it on only to listen to music and rarely watch movies, well, surf the Internet, but I don’t use it at all. Didn't smell burnt. Well, except from my fart.

it make sense to call a specialist at home?

Answer 1

Call a specialist at home only if this is your friend, or from friends (well, or suddenly you are 2x2 meters in size and make it clear that it is better not to try to throw you). Many companies that do this are scammers, and you never know if you will get a good one or not.
In general, if money allows, you can buy the same motherboard, and try to make sure that it's the case. (if not in it - return it to the store, say that it did not fit).
You can also check the power supply - if possible, take it from acquaintances / friends / colleagues, they are almost all universal.
If the computer is under warranty (you say that it is about a year old) - carry the motherboard under warranty (although it all depends on the type of warranty - if the warranty is for the entire computer, it can be more difficult, in which case it's better to google).
Good luck to you :)
