Final answer:
When fans get loud and disappear after opening the task manager, it could indicate a virus or malware, system overheating, or inadequate RAM.
Step-by-step explanation:
When fans get really loud and disappear after opening the task manager, and something is using 99% CPU, it could indicate:
- A virus or malware: If a computer is infected with a virus or malware, it can cause the CPU to be overworked, resulting in loud fans.
- System overheating: If the computer is not properly cooled, the CPU can overheat, which can cause the fans to become loud. Opening the task manager may temporarily relieve the strain on the CPU and decrease the fan noise.
- Inadequate RAM: If the computer does not have enough RAM to handle the processes it is running, the CPU can become overloaded and cause the fans to become loud. Opening the task manager may help identify the programs using excessive memory.
