Try to turn on the computer, press the power switch, and hear a buzzing sound on the main unit, which is the power fan in the main unit starting to turn. Wait until the screen flashes brightly, and then flashes, and it is black, and there is no response.

It's really as cross-eyed said, there is no reaction after turning on.

The old way, flip the book.

Reading according to the script is the experience that Li Zhengyi summed up during this time, and when he encountered general minor problems, he basically had them in the two books he bought. It's all about the church, such as plugging and unplugging hardware, moving gold fingers, wiping dust, etc., Li Zhengyi can memorize it.

Usually squatting at the bar, holding two basic computer books to gnaw, Li Zhengyi accidentally found a small surprise. I don't know if it's because of rebirth, Li Zhengyi's thinking, memory and spirit in this life have improved a lot compared with his previous life.

When he was first reborn, his physical condition was the same as he remembered, not very good, not bad. But in terms of physique, it can't be compared with the physical fitness of a forty-year-old in the previous life. I didn't feel much about thinking, memory, and spirit at the time, but later I was busy making money, so I didn't think deeply about it.

It wasn't until he bought these two computer books back and was forced to read them by computer problems in Internet cafes that Li Zhengyi slowly discovered the changes in his thinking, memory, and spirit.

First of all, memory, which refers to is not the impression of those past events in the past life, but the ability to remember. Li Zhengyi remembers very clearly that whether it is in his previous life or in this life, his memory ability will definitely not reach the realm of never forgetting ten lines at a glance, and it can even be said that he is worse than ordinary people. I used to go to high school, memorize English words, and often turn a page of a book, and my mind was blank when I read something in front of me.

Now, when looking at the basic knowledge of computers, Li Zhengyi's feelings are completely different. Of course, don't get me wrong, he also doesn't have the ability to never forget ten lines at a glance now, which is a skill that only appears in urban immortal cultivation novels. But after watching it, my mind is no longer blank, and there will be a deep memory picture. If you try to review it twice, basically after thirty or fifty days, you can still remember most of the key content very clearly.

The second is thinking, which refers to the ability to think logically and understand, which can only be truly experienced when reading a book. Li Zhengyi in his previous life, no matter what book he read, was superficial, he continued to read if he could understand, and if he couldn't understand, he just threw the book aside.

This is also the direct reason why his three-year high school reading performance seriously dragged down the class, and it can even be said that the school was seriously delayed. Nowadays, when I read the computer books I just bought, I was still apprehensive, worried that I wouldn't be able to read them, but I didn't want to read them more and more, and I didn't have any reading disabilities. The understanding of reading the book is combined with the actual operation of the computer in the Internet café, and afterwards I feel like this.

As for the spirit, it is purely a personal feeling, and there is no intuitive appearance that can be observed. The general range that can be guessed, that is, attention, fatigue, thinking and memory aids, and the grasp of behavioral perception.

All of this, all the anomalous abilities that are quite different from his previous life and cannot be understood or explained, Li Zhengyi attributed the cause to his greatest supernatural phenomenon - rebirth.

Because of this, Li Zhengyi is now full of interest in learning. On the one hand, the source of motivation is caused by his own specificity, and on the other hand, the current situation of Internet cafes forces him to study.

Just like now, Internet café computers are the most vulnerable piece of hardware, running 24 hours a day, like an overloaded maniac working day and night. One day, a component will be damaged without warning and will have to be repaired or replaced. As for the keyboard and mouse, the most commonly used parts of Internet cafes, because they do not support hot-swap processing at present, the failure of the keyboard and mouse basically happens every day.

Li Zhengyi quickly flipped through the books and did not find the corresponding solution to the problem. I had no choice but to use my own understanding to rule them out one by one. He disassembled the computer host, unplugged the graphics card and memory module, wiped the gold fingers of these two parts with an eraser, and plugged in the computer again, but it still didn't work. I removed the CPU again, found that the silicone was normal, plugged and unplugged the hard disk cable, and turned on the computer after installing it, but there was still no response.

At this point, Li Zhengyi has no choice, he will only be able to do these three axes at present, and he will call it a day after playing. I thought about changing the hardware to try the effect, but because the business of the Internet café was too good, it was full, and there was no computer hardware to replace it. In the end, I really couldn't do it, so I could only pick up the host and find a professional computer store master to solve it.

There is no large computer city in Qingyun School District, but there are still computer stores. With the rapid development of the school district, places like computer shops or computer training rooms have begun to spread out, which is more and more convenient for the citizens of Qingyun School District.

Li Zheng unplugged all the cables of the computer that had problems, and said to Cross-Eyed and Luo Wei with the host computer: "I'll take it to the computer store here to find the master and take a look, you two should rest and go to work." ”

Carry the host out of the door and walk along Cuiting Road towards the city.

There is a computer repair shop not far away, which specializes in solving all kinds of incurable diseases for Internet cafes in this area. In less than 20 minutes, Li Zhengyi found the ground and told the maintenance master about the phenomenon.

There was a master in the computer shop, about thirty years old, with eyes. He carefully repeated the routine that Li Zhengyi had tried just now, and found that there was no response, so he began to replace the hardware for debugging.

In the end, all the hardware on the motherboard that could be replaced was tried, and it was found that it still didn't work, so the master turned on a small flashlight and began to shine back and forth on the computer motherboard. After a while, it should have found something and said that there might be something wrong with the motherboard.

Remove the motherboard, replace it, and try it, the host computer boots up, and the connected monitor starts to display the boot screen.

Li Zhengyi asked: "Want to change the motherboard?"

The boss said, "It's better to replace it, it's not cost-effective to repair." ”

"How much does it cost to change the motherboard?"

“400.”

"So expensive?" Li Zhengyi was a little surprised.

The maintenance master should be the owner of the shop, and he said without humming: "It's all at this price." ”

Li Zhengyi said: "Then you repair it for me first, how much does it cost?"

The boss hesitated: "You can fix it, but to be honest, I can't guarantee that it will be repaired, your motherboard capacitor circuit is a little faulty, and it is risky to repair." ”

"It's okay, fix it first, and then talk about it if it's broken. ”

"Oh well. "The owner of the store is a little helpless, and it is the most troublesome to meet a customer like Li Zhengyi.

"How long will it take?"

"It's about 3 o'clock. ”

Li Zhengyi said yes, then went out, walked a few steps and turned back to ask the boss: "Master, do you know where there are people who learn computers around here?"

The shopkeeper looked up and asked, "Hardware or software?"

Li Zhengyi scratched his head, learning computers is divided into hardware and software? Aren't they all taught together?

When the shopkeeper saw Li Zhengyi's appearance of wanting to speak and stopping, he knew that there was a computer blind standing in front of him, so he explained: "To put it simply, hardware refers to the computer equipment itself, just like I repair the motherboard for you." Software refers to applications that run on computer hardware. ”
