That brother came to help me 20

I'm doing the work of repairing the motherboard.,The general IDE1 can do CD ROM,IDE2 I didn't care.,It's recommended to take a look at the CMOS settings.,It's estimated that there is a problem with the settings.,It has nothing to do with your hardware! Even if it is new, it should not be a hardware failure, so it may be the following situations:

1. Check the hard disk and optical drive jumper;

2. Enter the BIOS setup program and set it as the default value of the system;

3. Replace two new data cables.

Even if it is new, it should not be a hardware failure, so it may be the following situations:

1. Check the hard disk and optical drive jumper;

2. Enter the BIOS setup program and set it as the default value of the system;

3. Replace two new data cables.

Hehe, I don't know if it can solve your problem. , my email is:

Check whether there is a problem with the data cable, to make sure that the hard disk and optical drive must be good (try it on other machines), turn all the IDE to Auto in COMS, unplug all the line caps of the hard disk optical drive, and let the cable identify and try.

If you say so, it's not the motherboard's problem, it's your data cable.

Many times, don't underestimate the data cable, I have encountered a lot of data cable problems.

Could it be a jumper issue? Let's skip to automatic recognition.

The number of wire holes is not unseen.

When we multitask, we become sluggish.

When the brain has to multitask, the reaction becomes slow. In one experiment, researchers asked adults between the ages of 18 and 32 to identify two images: a colored cross and a geometric shape, such as a triangle.

It seems simple, right? However, when participants saw colored crosses and geometric shapes at the same time, they needed nearly a full 1 second of reaction time before pressing the button. Even so, they often make mistakes.

If participants were asked to identify the image of the colored cross first and then the geometry, the process was twice as fast.

Maneuvering between tasks creates other problems. We may forget what we were doing, or what we wanted to do. The to-do list in our brain, known as "operational memory", records things we need to remember temporarily, like an email address that has just been told.

But the content of "operational memory" can evaporate like water in a desert; After only about two seconds, it begins to disappear. After 15 seconds of thinking about a new question, you'll forget about the previous question. In some cases, the forgetting rate can be as high as 40.

Studies in the workplace have found that it takes up to 15 minutes to regain a high level of focus after being distracted.

This coincides with the researchers' observation of the work habits of Microsoft employees. After a group of people reply to an email, it takes an average of 15 minutes to refocus on a major task, such as writing a report or taking a computer**. Why is it so long?

Often, employees are distracted by replying to other emails or browsing the web.

In the cubicle of the office, we were safe (most of the time). But in the real world, multitasking can be dangerous. In 1999, the U.S. Army studied the effects of using mobile phones on driving ability.

In conclusion? All forms of mobile phone use have led to a significant reduction in the ability to cope with road traffic conditions. 」

This is even more true for older drivers. As we get older, the harder it is to get out of distractions. After the age of 40, the decline is significant.
