1. Motherboard: The mother board is the primary hardware component in any Windows system, as it houses the central processing unit (CPU) and other vital hardware components. A malfunctioning motherboard can cause a range of issues, from random freezes or crashes to boot failures.
2. RAM: Random-access memory (RAM) is essential for Windows systems to run properly. Without sufficient RAM, the computer’s performance will be poor, causing programs and applications to run slower than normal. A faulty RAM module could result in frequent crashes, instability, and slow performance.
3. Hard Drive: The hard drive is responsible for storing all the data on your system. It can become corrupted due to a power failure, a virus attack, hardware failure, or other factors. When the hard drive fails, it can cause system errors, unexpected shutdowns, and data loss.
4. Power Supply Unit: The power supply unit (PSU) is responsible for supplying power to the other components in the computer. If the PSU fails, the other components may not receive adequate power, resulting in random shutdowns, corrupted data, and other system issues.
5. Video Card: The video card is responsible for displaying graphics on the monitor. Issues with the video card, such as an overheating problem, could cause the screen to appear distorted or pixelated. In some cases, the video card could even cause the system to crash.
6. BIOS/UEFI: The basic input/output system (BIOS) or unified extensible firmware interface (UEFI) is responsible for controlling system resources and interpreting commands from the operating system. A corrupt or outdated BIOS/UEFI can cause random freezes, unexpected reboots, and other system issues.
7. Cables and Connectors: Faulty cables and connectors can prevent components from sending and receiving data. If a cable is damaged, it could cause system instability, random freezes, and other issues.
8. Cooling System: The cooling system is responsible for keeping the components in the computer running at optimal temperatures. If the cooling system is defective or inadequate, the components can overheat, resulting in random shutdowns, data corruption, and other system issues.
9. Fans: Fans are designed to draw cool air into the system and exhaust warm air out. If the fans are not working properly, the system can overheat, resulting in unexpected shutdowns and stability issues.
10. Optical Drive: The optical drive is responsible for reading and writing data to CDs, DVDs, and other optical media. If the drive is failing or has become damaged, it can cause data loss and other system issues.
