Question about MSI K7N2 DELTA2-FSR NVIDIA nFORCE2 ULTRA 400 CHIPSET SERIAL ATA150 ATX FORM FACTOR 1xAGP(8X)/5xPCI/... Motherboard

1 Answer

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

My system will not start up. When I press the power switch, the CPU fan spins once and then nothing happens. After this, the system is completely unresponsive unless I turn the power supply off and back on again, then I can spin the CPU fan once more.

I have verified that I have a good power supply. I have removed all peripherals from my motherboard and only connected the 20-pin power and the 4-pin power to the motherboard. So there is only the power supply, motherboard, cpu, and the ram, nothing else. In this configuration, the "spin once" behavior occurs.

If I remove the 4-pin, the cpu fan will come on, but the system will not POST. I believe that this is probably the CPU, because the 4-pin supply powers the CPU. Is any way I can verify which component is bad without buying a new one of each, one at a time, and installing them?

Oh yeah, this first occurred when my old power supply died (I could smell electrical death in the guts). Before my old power supply crapped out, the system ran fine, and it had the 20-pin and 4-pin connected.

    Thanks for the input. Though I don't want to throw away a good CPU, if the motherboard is the only thing that's bad. Or vice versa. Any suggestions on how I can determine the culprit(s)?

    Good point. Thanks for the help. I think I might just do 'em both and maybe up my performance while I'm at it.
    Cheers

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.

    Only by replacing one at a time - it's unlikely that the CPU will damage the board, it will just churn out garbage if it's not working right, and nothing will start. However, the board can affect the CPU more, so I would start by changing the board. Problem you have, is that you could replace the board, and then the CPU goes faulty after a while, due to damage already done shortening it's life.

My lenovo i5 laptop suddenly switched off
The CPU could be overheating.
When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

If you're referring to the fan on the CPU , and it does not run when you turn on the computer , yes replace it. The system is protecting the CPU from overheating . If you're not sure if the fan is bad , remove the computer access cover to the main board , then , turn the computer on and see if the CPU fan starts to spin. If you notice the fan blades vibrating or jiggling but not spinning , then replace the fan motor assembly .

I hit the power button and the light blinks once, the fans will start to spin, and then nothing, no power no boot, just a quick blip of power but no power up..
You need to remove the case top and look for a lot of Dust all over the inside, especially around the CPU making sure the cpu fan is still running. This can get expensive when maintenance procedures are not thought of until late. It's not you it's everyone. With the power cord out, maybe you have a vacuuum attachment to get in there and get rid of a lot of spider webs. Then take a slightly moistened rag and complete the job. I can't guarantee your CPU fan is still alive but when you get all cleaning utensils out of the way, put the power switch on and watch for the CPU fan to spin. If not- any lights? P.S. Fan?

Ensure that the power button is pressed and the monitor is plugged in correctly. If ok, then the installation was stopped while installing your video drivers. If possible use another monitor to re-load the xp operating system until completed. Once the video monitor drivers are loaded the monitor will work again. Let me know if you have any questions.

My system doesnt start
if no beeps (remove the RAM and for sure has to beep if the motherboard is OK) at all and no video signal you may look to:
1. a new PS - power supply or
2. a new CPU or
3. a new motherboard.
