The PC works very slowly

Solution

• Before entering the Operating System A set of instructions that tell a computer on how to operate when it is turned on. It sets up a filing system to store files and tells the computer how to display information on a video display. Most PC operating systems are DOS (disc operated system) systems, meaning the instructions are stored on a disc (as opposed to being originally stored in the microprocessors of the computer). Other well-known operating systems include UNIX, Linux, Macintosh, and Windows.

• • Hangs during POST POST (Power-On Self Tests), try to determine which device is always being searched when the PC hangs:

  • Take off the unnecessary device to see if that speeds up the PC.

  • Change the hardware The physical and mechanical components of a computer system, such as the electronic circuitry, chips, monitor, disks, disk drives, keyboard, modem, and printer. one by one

• Hangs at the Windows Login

• • Enter safe mode to see if the issue is still evident

  • Re-install the drivers

  • Re-install a new "clean" Operating System A set of instructions that tell a computer on how to operate when it is turned on.

• • Check if the system configuration fulfils the minimum requirement of the software Computer programs; also called “applications.”

  • End the process which takes up the most CPU usage

  • Please optimize the system

• Only runs slowly when connect to the internet An international conglomeration of interconnected computer networks. Begun in the late 1960s, it was developed in the 1970s to allow government and university researchers to share information. The Internet is not controlled by any single group or organization. Its original focus was research and communications, but it continues to expand, offering a wide array of resources for business and home users.

• • Change the network A system of interconnected computers. cable to see if the speed changes

  • Scan for any virus An unauthorized piece of computer code attached to a computer program or portions of a computer system that secretly copies itself from one computer to another by shared discs and over telephone and cable lines. It can destroy information stored on the computer, and in extreme cases, can destroy operability. Computers can be protected from viruses if the operator utilizes good virus prevention software and keeps the virus definitions up to date. Most viruses are not programmed to spread themselves. They have to be sent to another computer by e-mail, sharing, or applications. The worm is an exception, because it is programmed to replicate itself by sending copies to other computers listed in the e-mail address book in the computer. There are many kinds of viruses, for example: Boot viruses place some of their code in the start-up disk sector to automatically execute when booting. Therefore, when an infected machine boots, the virus loads and runs. File viruses attached to program files (files with the extension “.exe”). When you run the infected program, the virus code executes. Macro viruses copy their macros to templates and/or other application document files. Trojan Horse is a malicious, security-breaking program that is disguised as something benign such as a screen saver or game. Worm launches an application that destroys information on your hard drive. It also sends a copy of the virus to everyone in the computer's e-mail address book.

  • Please optimize the system

• An abnormally high temperature causes the slow speed

• • Check the fan settings in the BIOS BIOS, in computing, stands for basic input/output system. BIOS refers to the software code run by a computer when first powered on.

  • Improve the heat transfer conditions

  • Please optimize the system

CPU fan is too noisy

Solution

• Check if the CPU fan is damaged and whether the fan is well connected to the motherboard
