First thing to try is running the fan off a separate power source. Fans do die, or get stuck.

If that works, you need to find out why the fan isn't getting power. That could be as simple as a loose connection, or as complicated as the drivers not properly responding to CPU temperature.

Have you made sure that the pins to where the fan connects are clean from any dust? if not, just use a cotton swab to clean the pins then, blow on the connecter for the fan. make sure that the fan is also clean from any blockage. if none of that works just set the fan up to another fan slot. if your computer is like mine it should say 'fan 1' or 'fan 2' around the plug in. if that dosent work, well, then, your fan is screwed my friend.

Unplug the fan and test it with 12V.
Do check your BIOS isn't doing anything silly with "smart fan control"

The fan will plug into your board (and unplug) it'll run on 12V For BIOS look at the screen when it starts up for the phrade "Hit DEL to enter Setup" or similar. L

I had a problem while building my PC.

There are two connections that go onto the motherboard.. one main one (20 pins or 24 pins) and a smaller 4 pin one (This may differ from one psu to another) Make sure this four pin bit is connected (usually near the fan)

If not, probably loose connection, broken fan, etc..

Is it a home built or bought?

If it is home built the psu might not have all the required wires to plug into the mobo. Like I said before, the fan usually runs off a separate wire to the mobo. Check to see if there are any bits that look like they need bits plugging into them...
