Acer aspire x3470 not booting up

Thijsl

Hello there.,
Today i plugged my Acer aspire x3470 quad core amd vision 6 and pressed the power button. But nothing happened so i went listen carefuly and all i heard was almost unhearable beeping sound. Please can someone help me.

The one in the middle of the board is typically the CPU fan. A PSU fan will be inside the power supply, a case fan will be either at the back or the front of the case and a GPU fan or fans will be mounted to the graphics card.

So, if that fan is getting a blip that tries to spin it but it doesn't come up all the way there are a few options, most of which aren't good. Easiest is that the fan has failed and won't spin up, and since the motherboard might be able to verify it's running it would likely shut things back down if the fan doesn't indicate it's running. The fix is to replace the fan with one that's similar, same size, same connector. If the fan is bad that would get you back up and running, though I'd also take the opportunity to vacuum out the heat sink (you really ought to do that every six months or a year anyway). If the fan is good then the problem is likely in the motherboard or power supply. We can probably assume the power switch is good since it does try to start when you press the button. The power enable circuit is on the motherboard and if it has failed then we're looking at close to the worst case, it'd mean a full motherboard replace, and motherboards often take other things with them when they blow, so even a swap of the MB may not get you back up. If it's the power supply that's kind of in the middle between replacing the fan and replacing the motherboard. The power supply may be blown such that when the power enable circuit tells the PSU to start it send out enough juice to try to get the fan going, but then fails without any more power available.

Diagnostics are going to depend somewhat on what you have available to work with. If you have another fan in the system (such as a case fan) you could test by plugging the other fan into the CPU fan connector and power up. If it starts trying to boot and the fan spins then shut it back off immediately and replace the now known to be bad CPU fan. If the case fan acts the same as the CPU fan then try either the power supply with a different system or a different power supply with this system. If you don't have access to another fan or another PSU then you might think about leaving the rest of the testing to a local technician...

I mention the beeping sounds came from the fan

Do a power reset, turn it off then pull the power plug and press and hold the power button for 30 seconds. Put the power back in and turn it on. If the problem is either a confused power supply or a stuck sleep mode that should get it. Report back and we'll continue diagnostics if that didn't work.

I will try it later today thanks for helping.

Billsey, I've tried it but no success. I've even tasted it for 1 minute but no. But thank you for helping

OK, so next we need to know which fan is running. Could you open the side and try a power on? You should be able to tell which fan is making the noise, don't forget there is a fan inside the power supply itself as well as CPU, video and/or case fans.

It's the fan above the cpu/gpu that one in the middle.
