Need help.
This was intermittent for several start ups, now won't work at all.
PC starts to boot up, then a message .. "CPU FAN is not connected".
The fan is plugged in to the mobo but looked like it was spinning at about half speed.
I put another fan on and it spins up to what looks like a normal speed but the PC still won't boot up.
Get the same message then it shuts down.
Yesterday after 4 attempts, it finally took off and ran normally.
Now it won't start even after umpteen attempts.
Any help needed badly.
Thanks,
Russ

You could start on the bios and disable the CPU fan warning.

This not really recommended but give it a try.

Hi Jeff,
How do I get there.
There is a very brief screen, then the message.
Thanks

Depend on what type of computer you have.

It is written when the computer boot.

Normally, this key is Delete

Jeff

Normally, is you can enter in the BIOS, you should find under PC Health status the RPM for the fan.

If is is spinning, try reducing the RPM a bit to see if it's make any difference.


Jeff

Jeff,
This is the only screen I get for about 3 seconds, then the FAN message, then it cuts OFF.
I can't get to the bios or anything else.
It is just a mobo mounted in my panel, not sure what it is. lol
Thanks

when booting up, if you keep hitting DEL key, you can't get access to the BIOS???

This sound bad, look like a bad hard dive.

But even with a bad HDD, you should be able to access BIOS


Jeff

Try downloading the manual for your mobo.

Sometime on some mobo, there's a jumper to skip or prevent access to the bios.

What brand and model is it.

Jeff

If your computer does not boot at all, you will probably need to clear bios setup, it may be corrupted.

Or just to be sure, verify that keyboard is connected.

Jeff

To be honest Russ it sounds like the mobos sensor is screwed but check the fan is connected properly and to the right header as often there are at least 2 or 3 fan headers. Also worth cheking the wires on the fan as there should be at least 3 possibly 4, if the fan you put on is from an old computer it may just have 2 wires.
