I finally found a good service where they don't cheat. The fraudsters have lost their RAM and need a replacement. Instead of throwing out the RAM and paying 450 rubles for a replacement, the guys here restored it and announced an adequate, acceptable amount. Thank you!
Perhaps the most honest guys that I have seen when repairing computers, without divorces. I recommend. Even I was not too lazy to make a review, (for the first time)
The computer did not turn on, because there were very important documents there, I was ready to pay any money. I traveled around several workshops beforehand, everywhere they put up a preliminary price of 200-300 rubles for work and waited a day or two (apparently they estimated by how much I was in a panic and did not understand), I thought OK, probably it's necessary. I decided to play it safe and Google it again and got an advertisement for this workshop. They examined the computer when I was there and said that the RAM stopped working, the replacement was 50 rubles, they changed it and everything started. It took at most 15 minutes.
Thanks to Alexey for his honest and fast work, I will advise everyone!
