Solved: My Computer Doesn't Detect My CPU Fan

After they've left take the power supply out of their computer . When this happens then you'll have your culprit. The computer should run until it overheats, then shut down. I disconnected it last week to see if it corrects the problem but it didn't do anything. https://forums.techguy.org/threads/solved-my-computer-doesnt-detect-my-cpu-fan.752780/

So if I leave it alone after hitting the power button, it will run for 3-4 seconds, turn off, pause, turn on, 3-4 seconds, turn off, repeat.

All other fans in the case are working normally So I'm assuming the stock fan is just dying? This goes on until I flip the switch on the power supply to break the cycle, but I've noticed that the fan will sometimes get a little 'shot' when I do

There could be an option to stop monitoring your CPU fan speed (I doubt it), and there should be an option to stop it from asking the pressing of F1, if Would it be a bad idea to let the computer keep idling so I can wait to see if/when it turns itself off, or would that just cause damage I don't Also, the fan has an external mount for the CPU fan controller and i connected that to it. I had my DVI cable connected to the secondary DVI port, but if I switched the cables after POST, I still had no video.

Or maybe even something more serious like your motherboard crapping out. Hope this helped. Needless to say I was a little shocked so I tried again, same thing. Stay logged in Sign up now!

Sorry. Everything appears to be fine, except the CPU fan isn't spinning all the time. Hooray for The System! Now unhook your power supply and hook your friend's up to your motherboard.

An error (403 Forbidden) has occurred in response to this request. If you'd rather have the fan spin all the time you should be able to disable the fan speed control in BIOS.

Also, try unplugging everything but the bare essentials, try putting RAM in a different slot, basically anything you can do to narrow it down to one specific component. http://blightysoftware.com/solved-my/solved-my-ei-system-computer.html not sure but its probably mounted and cooling correctly if your cpu isn't overheating lilLB, Sep 23, 2008 #2 BG-0 Joined: Dec 31, 1969 Messages: 6,922 You propably can't do Peeked into the side window and noticed that the CPU fan was not spinning, so I assume it's turning itself off as a precautionary measure. Well, either that or your power supply is bad (best case) or your power supply has overloaded and taken the motherboard with it (worst case).

Now, with your computer on its side, plug it in and turn on the power as normal. If the fan you just plugged in starts to spin then you're in business (Woo Hoo!). I've confirmed this to be the case with two separate, known good PCI-E video cards, two different sticks of RAM, and the bare minimum of stuff plugged into the board (video have a peek here If it spins this time then you know that the power socket on the motherboard is dead.

There was no onboard video on my motherboard, but if there was, that would be a good thing to try. Don't let the computer stay on for more than a few seconds.

As stated above many motherboards will shutdown after a few seconds if no fan rotation is detected. Yes, my password is: Forgot your password? You're absolutely right, it's shutting down to prevent serious heat damage. Hooray for rules!

It might also be worth nothing that the monitor does not get a chance to display anything for the couple seconds that the tower is on, just 'PLEASE CHECK SIGNAL CABLE' This site is completely free -- paid for by advertisers and donations. So I don't think it's shutting down as a protective measure. http://blightysoftware.com/solved-my/solved-my-gf-s-computer-log.html Short URL to this thread: https://techguy.org/752780 Log in with Facebook Log in with Twitter Log in with Google Your name or email address: Do you already have an account?

It freaked me out something fierce at first, until I realized that there's some fan speed control stuff enabled by default in the BIOS. Thread Status: Not open for further replies. I just built this thing like a month ago and have not had any problems besides this.

Crisis averted. Seriously though.Our rules have been updated and given their own forum. Explore the BIOS a little.
