sound. If it is not a memory reason, please switch to a normal CPU and power on again. 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."

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
The firewall can be divided into software firewall and hardware firewall as well as chip-level firewall if it is divided from the soft and hardware form of firewall.
The first type: Software firewalls

Now the trend of Web site development to the use of Network Load balancing with the increase of the size of the site according to different stages to use different technologies: 1. Hardware-level load balancing
This load balancing is done through hardware, and common hardware has more expensive commercial load balancers such as NetScaler, F5, Radware, and array.
Believe that as long as the user is using the router, have encountered a router failure, resulting in the problem of the Internet, electronic products in the course of the operation of the failure is inevitable, this article mainly to give you a detailed introduction of broadband routers often appear in the hardware and software failures and solutions, hoping to help everyone

Definition of hardware encryption and Software Encryption 1. hardware encryption is implemented through a dedicated encryption chip or an independent processing chip. When the encryption chip, private electronic key, and hard disk are matched one by one, the encryption chip maps the encrypted chip information, private key information, and hard disk information a

Wireless sensor networks are emerging and have great potential for development. In the course of a new technological development, various related energy design, energy-saving solutions, optimization problems, and security issues need to be fully considered. This article briefly introduces the development process of wireless sensor network software and hardware.
The Research on wireless sensor networks is i
Generally speaking, 32-bit and 64-bit systems have two differences: hardware and software.
Hardware:The 64-bit and 32-bit architectures are different. Here, the 64-bit technology is relative to 32-bit, which refers to general-purpose registers (general-purpose register) the data width is 64-bit, And the 64-bit instruction set is the command to run 64-bit data, that is, the processor can run 64-bit data at a

. 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 memory is faulty, an alarm should be reported.

Three steps for Embedded engineers in software and hardware
Hardware path:
Step 1: PCB design, which is generally used to cut and expand the circuit of the Development Board. Based on the principle diagram of the Development Board, draw the PCB and package library and design your own circuit.
Step 2: You can develop the system on an FPGA, CPLD, or other
Part 5: BIOS settings BiOS (Basic Input/Output System) is installed on the motherboard Flash ROMProgramIt acts as a communication between the hardware and the operating system. Through the bios, you can set the operating mode and parameters of the hardware. When the system is turned on, the BIOS will first perform the boot self-test (post ).
