    When you replaced the psu, did the cpu fan work ok for the specified time?



    How long has this problem been occuring?



    Did you upgrade or replace something just before the problem first occured?

You seem to have a lot of hardware in there, so trying to remove some items to lighten the Power Load was a good idea - but maybe too late.

Check your Power Supply - I suspect that you will need around 550 Watts or more. If you can put in another Power Supply (after disconnecting as many drives etc as you can) see if the problem re-occurs.

If it does not, then your Power Supply is failing and will need to be replaced (with a 550 Watt or above PS Unit). I would personnally think that a 700 Watt unit would be ideal if it were my machine.

Yeah, I know you said you replaced the Power Supply but didn't say if everything was reconnected nor what size Power Supply Unit you put in.

Good luck.

It booted up once, and now fails?

Quite likely it is defective. If it booted once, it should boot again.

Make sure the little SQUARE 4-wire plug from the power supply is also plugged into the Mobo. Commonly overlooked, and can drive you nuts trying to figure out.

Best 'o luck, Barry.

I have got a system with an Aopen motherboard which having only a 20 pin connector for smps connectivity. the Atx smps i have is is 24 pinned. i can connect the main line by splitting up the 24pin...


The actual Processor fan connects to the CPU Fan header on the mainboard. It's 4 small pins. It plugs in right near the CPU socket on the mainboard. Check the user manual for exact placement, you may download it from the AOpen website if you don't have one already.

Plug in the 20Pin connector if that is the most Pins that the mainboard will allow. Cable tie the other 4Pins back onto the 20Pin connector.

Then if there is additional 4Pin connector required by the mainboard for CPU power and you don't have that connector on you power supply, you will need to purchase a Molex to 4Pin CPU power connector. When you go to the computer store check with them that all is correctly connected.

Take care!

Cpu fan stop few second after starting pc


Hello,have you installed new motherboard or CPU?
Follow these steps again
1) Disconnect the power cord from the back of the computer & open up the case.

2) Wear an anti-static glove or at very least discharge your static by touching a metal surface or power supply

3) Disconnect the main 20pin ATX power connector from the motherboard & the square 4pin ATX2 power connector

4) Remove any PCI cards you have & disconnect ALL drive cabling from the MOTHERBOARD. Also disconnect any internal USB fly leads from the motherboard.

5) You should now have ONLY the cpu+heatsink/fan, memory & video card installed. Locate the round silver battery in the bottom right corner of the board. Just below it, you'll see a plastic jumper cap. This cap should be covering 2 pins (pins 1 + 2) with pin 3 bare. It will be marked JP1. Move the jumper to cover pins 2-3 instead. Leave in this position for about 30 seconds, then return the jumper to its original position (pins 1-2).

6) Reconnect the square 4pin ATX2 power connector & the main 20 pin ATX power connector. Make sure that the case speaker or buzzer is connected also.

7) Make sure the only external devices connected are the keyboard/mouse & monitor. Reconnect the power lead & power on the system

Let me know what happens

System won't turn on but when i pushg down on one side of the power suply connectore the fan starts running but computer stioll won't turn on it used to boot up then opne day stopped


It sounds like you have a faulty connector - I would return the item under warranty. Otherwise, if it is out of warranty, you will have to source a new motherboard.

Remove the battery. Try again. If the PC starts, change the battery.

System will not start up. Cpu fan spins once, then nothing.


It is more than likely that when your old power supply died a death, it damaged some components on the motherboard. Replace the Motherboard and chip, and you should be back in business. You can pick up some good value bundles to save money on buying the parts seperately. The power supply working again after turning off and on, is because there is a little trip in the power supply that triggers when it detects a fault. Powering down resets that trip allowing it to try and work again.

System and Processor fans don't spin- anything else is working


Your description indicates your power supply may be faulty or there is a break somewhere in the 24 pin main ATX cable wiring.
Swap out the power supply. Make sure your PSU has a 24 pin ATX connector & (not a 20) pin & a 4 pin ATX_12v connector for the CPU.
