Case Fan problem.
Hello , some days ago my pc gave me a black screen , I had to restart it manually , once it booted and three mins passed , it shut down alone. It was not a forced shut down , it was like if it lost electricity. Since that , one of my four case fans stopped working. I even replaced it but again nothing. Its connected to the mobo. Could it be a psu failure ?

I don't have another atm but I m gonna replace it asap. Today I tried to connect the fan with a molex to the psu and it works fine. Guess im just gonna get a new psu to avoid such failures again.

It does sound like a PSU failure. Do you have access to another PSU you can use to check? If the PSU is faulty, it may have burned the fan header.

Forgot to say , pc is running smoothly. It was the first time it gave me a black screen in one year. The entire pc is new except for the PSU which is three years old ~
