My best friend’s computer is experiencing the following error message every time he started his personal computer “PC fan has failed” while the black screen on the other hand can be observed. Then it directed him to hit the F2 for him to proceed to the next interface. Before, it took for about 5 minutes for his computer to shut down but recently he had observed that it already took for about 10 to 15 minutes to shut down.
One of our friends suggested to him to open the case of the system unit to double check if the fan is mounted properly and we found out that the fan is in the correct connector. We also cleaned the fan as well as the rest of the motherboard and restarted the computer again, but the same error has been displaying.
Can you please tell me what’s wrong in this situation?
