You did not specified which fan, there is several of them, and usually you do not change motherboard to fix fan, if fan on power supply stop, you need to change power supply, it is cheaper actually to exchange power supply than to replace fan, if this is processor fan, check first if it is plugged correctly to it's socket on motherboard:

1. switch off computer
2. remove power cord from teh back
3. remove side wall of the computer (left hand if you look at it from front)
4. remove processor fan from socket and then re-insert it
5. re-install wall, re-connect powercord and power up the computer
6. if this was just bad connection, you just fixed the problem :-) if this did not solved the problem, you need to purchase new fan suitable for the processor. This is LGA775 Intel processor motherboard, fan for it cost between $15.00 and $80.00 depending on the brand. You do not need to replace heatsink, I would advice replace only fan:
7. follow 1, 2, 3 and 4 then lift side tabs on the fan (over the heatsink, yo umau need little flatbed screwdriver as lever) and slide it out
8. insert new fan in exactly same position till tabs on the side click in
9. re-insert fan power supply to it's socket follow 5 and 6

If this is case fan, this is simple, proceed 1, 2 and 3, then undo screws (philips) holding fan, remove it's cord formteh socket, replace with same size fan, case fans cost from about $2.00 to about $50.00

if this is power supply, you need to purchase adequate power supply, it will cost between $20.00 up to $300.00, in your case $20.00 to $50.00 is fine... Please pay attentnion to rating and do not purchase any with less than 450w, they cost in my shop $27.00, do not bother with brandname!

Follow 1, 2 and 3
4. remove power supply from motherboard sockets, there will be 24pin socket on motherboard, look how it is oriented, replacement will fit only and only one way! remove power supply from fan supply (4 pin on the motherboard),
5. remove power supply from auxilliaries, hard disk drive, cd-rom and if any other, from them as well, do pay attention to orientation of the cables!
5. undo four screws on the back holding the power supply, support it with your hand while reomving.
6. insert new power supply (do pay attention which way it go on the back, yo uhave four screws fitting only in one way) and mount the screws
7. re-connect power to motherboard, wiggle it slightly in, do not break motherboard! same with fan power supply
8. re-connect power to auxilliaries, pay attention to sata connectors, they break easy
9. replace side, re-connect power supply and switch on computer, it should work now

Hope it did solved your problem, please do not forget to rate! This is only reward whcih we have...

Computer fan turns on every 2 minutes and runs for 30 sec.

Does your computer seem to be running hot? If not maybe that's all the fan needs to run to do its job. The only thing you could try is to replace the fan.

The motherboard is detecting some "fault":
* RAM not properly "seated" in its socket
* video-card not properly "seated" in its socket
* "bad" RAM (that is not working correctly)
* overheating (fans inside the case no longer working)

Take your computer to a qualified technician, at any computer-store, for professional diagnosis & repair.

I have a lenovo 3000 n100 few days back i formated my hdd and installed windows xp over vista running before but now the is no display when i start my pc just a fan runs for a about 5 sec and then stop...

Hi. Since the computer is turning on we may try draining the electrostatic energy of the motherboard. Take out the batery and unplugged the power adapter from the wall socket. Press and hold the power button for 30 secs and put everything back in then turn ON the computer. If same problem appears then this cold be an LCD problem.

Gateway gt4010, wont power on.

The fan turning off will be the cause of the PC shutting down.
This could be caused by a faulty fan or bad connection to motherboard.
1. try reseating the fans power plug on the motherboard
2. if that doesn't help, try replacing with new fan.
3. if that doesn't work then most likely motherboard problem

Trouble shooting

OC failure = over clocking failure. Make sure the CPU fan is clean, free from dirt & dust. Check CPU fan plug is connected correctly. If the CPU fan still stops after a few seconds replace the CPU fan.
It's harder to find just a fan to fit your heatsink, which sits on your CPU. It is easier to find a new heatsink \ fan combo for your Intel. Use your manual to find what Intel chip is on your board. Use that information & search google for a heatsink & fan combo. Pay close attention to how your current heatsink is mounted to the Gigabyte board.
