Fans wont turn on

[crazyrocker43]

Alright well i switched some things with my sisters computer with my computer, meaning my video card, memory and ram. But i switched everything back and now my sisters fans wont turn on, and her computer shuts off because of it. The only ones that turn on are the ones in the power supply i have 2 more, 1 is on the back of the computer and the other is on the processer. All the plugs are back where they should and i dont know what could of happen. By the way b4 i switched everything 1 of her fans where loud but the computer was running fine for about a year, any help could be useful.

Which fan is it that is not working is it the CPU fan, case fan or power supply fan.

If it is the CPU fan you need to clean it because if the fan has stopped working that means the CPU is overheating but I would clean all your fans.

well if the pc shuts down after a few to ten minutes it is from over heating.
Do you get any blue screans of death (blue screen with or w/o error's)

dubble check to make sheer everything is plugged in all the way.

Try swooping out a good fan(s) with one of the non working fans.
That will let you know if u have a bad fan(s).
