Hårdvaruhaverier

Hårdvaruhaverier, or hardware failures, refer to the malfunction or failure of physical components within a computer or electronic device. These failures can range from minor inconveniences to complete system crashes, depending on the severity and the affected component. Common causes of hardware failures include physical damage, wear and tear, overheating, and electrical interference.

Some of the most common types of hardware failures include:

1. **Processor Failures**: The central processing unit (CPU) or graphics processing unit (GPU) may fail due to overheating, power surges, or physical damage. Symptoms may include system crashes, blue screens of death (BSOD) on Windows, or a complete lack of response.

2. **Memory Failures**: Random Access Memory (RAM) can fail due to age, heat, or electrical issues. Symptoms include system instability, frequent crashes, and error messages related to memory.

3. **Storage Device Failures**: Hard drives and solid-state drives (SSDs) can fail due to physical damage, wear and tear, or manufacturing defects. Symptoms may include data corruption, slow performance, or complete failure to read or write data.

4. **Motherboard Failures**: The motherboard, which connects all the components of a computer, can fail due to age, overheating, or physical damage. Symptoms may include no power, no display, or intermittent issues with various components.

5. **Power Supply Unit (PSU) Failures**: The PSU provides power to all components. Failures can be caused by overheating, loose connections, or internal faults. Symptoms may include system crashes, component failure, or no power at all.

Preventive measures to mitigate hardware failures include regular maintenance, such as cleaning dust from components, ensuring proper cooling, and using surge protectors. Additionally, regular backups of important data can help recover from failures that result in data loss. If a hardware failure occurs, it is often necessary to replace the faulty component to restore normal operation.
