other computer doesn't work, you know that the object is out of the question. No problems continue to doubt, replace, and eventually will be able to find the problem object. 2. Direct observation method. The direct observation method is based on the bios of the alarm sound, post information on the instructions to determine the hardware fault. Troubleshoot problems based on a variety of sound and descript

Zhihu answered a question about book recommendation: Which of the following are the best recommendations? If you only recommend a computer-type God book, it must be code: Language hiding behind computer software and hardware. Eager to communicate is the nature of most people. In this book, "encoding" usually refers t

How is the computer getting slower? Teach you how to deal with it from two aspects: hardware and software! Everyone wants the computer to immediately enter the Windows system without waiting, or the system will not get slower and slower, but these aspirations are often unable to be fulfilled for various reasons, even w

I. Basic concepts of BIOS When talking about bios, have you been concerned about it? In fact, whenever you press the power key on the chassis, it will really work for you. So what is bios? The book gave us a definition: "BIOS is short for Basic Input-Output System (Basic Input-Output System). It is responsible for initializing, setting, and testing various system hardware at startup, to ensure that the system works properly. If the

Software-bound Computer hardware identification is an anti-copy method used by many software. However, it is not a simple matter how to determine the unique identity of the computer hardware. The following are commonly used method

. Check whether the fan is faulty. If the monitor is not damaged, check whether the CPU fan is running. For example, you can use a multimeter to measure whether the voltage output is normal as ± 12 V or ± 15 V. If the voltage output is abnormal, try another power supply. Iv. Detect CPU, video card, and memory If a black screen still appears, you can remove all components except the CPU, video card, and memory, and then power up the computer. If the me

If the black screen still appears, you can only change one motherboard, and the problem should also appear on the motherboard. In addition to the hardware cause of the black screen phenomenon, there are the following three aspects of the "soft" cause may cause "black screen." Software articles One,

Part 8: bios and CMOS FAQs When it comes to bios, most cainiao don't know much about it and dare not try it easily, as if they are naturally afraid of the blue screen, even many old birds cannot distinguish BIOS settings from CMOS settings. Therefore, before writing a Q A question, I think it is necessary to clarify these two concepts to get twice the result with half the effort.BIOS is short for Basic Input/Output System. It is originally intended to be "Basic Input/Output System ". What we u

, exponent is the digit (single-precision 8-bit, double-precision 11-bit), fraction is a valid bit (single-precision 23-bit, double-precision 52-bit).This is not quite like the scientific notation that we usually use.But this approach poses a problem, that is, when the effective bit exceeds a certain time, there will be a precision problem.// true // falseYes, it's equal.Because the first two will be stored as 1.000 ...

The poorest people in the computer market are counting the people who have moved faulty computers. Although the Assembly Machine has her strengths compared with the brand machine, it is her critical weakness to have no good after-sales service. Most computer faults are software faults, so there is no need to migrate the entire machine before it is determined to
