Question about AOpen AX34-U Motherboard

2 Answers

Power When I pushed the power button, the fans for the PSU and the processor would start and the power light would come on - then the power shuts down immediately. I thought it was the power pack problem, because it it quite old. So, I bought a 430W, but haven't installed it. Do you think it is the power pack? Secondly, the new new 430W PSU has a 4-pin +12V Power Connector. Does the AX34-U motherboard have two power connectors for the motherboard - one 20 pin and a second 4-pin. If so, where is the 4-pin connection on the motherboard? Thanks, Don

Hi 2VCRSDAD, no I do not think it's a power issue.
When a system starts but than shuts down before you can see any display or hear P.O.S.T. The problem is usually with a device connected to the board or the board. (Suggest you remove the memory & reseat. Making sure it is seated evenly.
Other simple suggestions. Did you check the CPU for bent pins before inserting into the socket? Did you place some thermal grease on the CPU before adding the heat sink & CPU fan assembly? Reset the cmos/bios page 18 in the manual.
Suggest you download the manual from Aopen, click on this link, for the English manual. (It takes a bit to open, wait for it).
ftp://ftp.aopen.com/pub/manual/mb/ax34u-ol-e.pdf

The main site for the Aopen AX34-U is below.
When the above site opens, you will need to set the dropdown menus. "EX:" (Motherboard), (AX34-U). (Driver).
http://global.aopen.com/products_download.aspx

The Aopen AX34-U board does not have a power 4-pin_12v connector. There are a few settings that must be set directly on the board though. Some of these settings refer to the CPU, sound & front case connecters to name a few. The manual is setup nicely. You will find it to be very helpful.
Take you're time going through the manual & setting the motherboards settings. If you find you need help regarding a setting, feel free to post it here & I'll help.

Good Luck!
Mike

You will have to get your power button unstuck. I do not know what type of button you have but if you would like to at least get your PC on without it instantly turning off, you can remove the power switch connector from the motherboard. You will eventually need to have the switch unstuck, or replaced though.

Show all solution to d945plrn motherboard problem not powering up


PSU IS OK? You're sure? You tested the 3 main voltages coming out?

DON'T rely on; "The LED lights are on, and the fans spin, so therefore the PSU must be good.

1) If ALL the LED lights were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor uses 51 to 125 Watts of power.

With a Power Supply that has a weak voltage power rail, you will see LED's light, and fans spin; BUT not enough power to turn the Processor on.

Power Supply also needs to be plugged into motherboard to test, because you need a Load on the Power Supply.

PSU is KNOWN to be good? I mean KNOWN.
Not, "It's brand new so I know it has to be good"
Okay, moving on.

CPU OK?
How did you test it? Install on another working motherboard?

Are the Electrolytic Capacitors on the motherboard good?

http://capacitorlab.com/visible-failures/index.htm

http://www.youtube.com/watch?v=Lut7MX5Dd_A

Capacitors on the motherboard are used as Filters, and Voltage Regulators.
The ones used as Voltage Regulators are in the Motherboard Voltage Regulator Circuit,

http://www.hardwaresecrets.com/article/616

Part of what the Motherboard Voltage Regulator Circuit does, is to regulate voltage for the Processor. (CPU)

The CPU MUST have a steady, 'clean', supply of voltage, and it MUST be kept within the Processor's voltage tolerance range.
Too much, or too little, and the CPU shuts off. BIOS turns it off.

(CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
I know you are aware, just posting for all those who read the solution in the future)

I have a emachine that powers ou, power pack fan, cpu fan but not the hardrive. It shut down and now won't start up. No beeps


Unplug from AC, open the case, clean if necessary, reseat the memory mods, use Electronic Contact Cleaner spray on contacts, plug in, push the on/off button. Does it begin to start, and in a few seconds completly shuts down? No LED's , no fans, nothing? Sounds like a PSU failure. Mine went out in 6 years.

Very similar problem

1. Is there a GREEN blinking light on the motherboard?

Your psu is works fine.
First open cpu cabinet and find motherbord.
Pull CMOS cell from m/b for 10 minutes.
Refix RAM Memory.

Then fix processor fan and processor.
Reconnect ATX connector to m/b.
Remove pci cards from PCI slot then check.
Let me know if you need more assistance.

PC SHUT down


three things i find to cause this,

one, the power supply is bad,
two, the power connector is lose or not push in
three, the heat sink on the processor has come off. This will cause the cpu to over heat and self shut off.

to test the power supply, pull the connector off the mother board and short the green wire to any black wire with a paper clip, this will switch on the power and see if it stays on.

if you need to replace it, you cannot use a regular atx power supply. E machines have a different pin out.

Psu shut down


99% TIME IT IS A FAULTY FAN GOING OUT.

REPLACING THE FAN INSIDE THE POWER SUPPLY WILL RESOLVE THE PROBLEM.

P/S ARE CHEAP, JUST BUY A NEW ONE OOR REPLACE WITH ONE YOU HAVE ON HAND

Emachine t5026 not power on. replaced psu.


I would test the memory. Also I think some computers will shut down if the fan on top of the CPU quits working. Or maybe one of the other fans or the Hard Drive quit and is drawing too much juice causing the PSU to shut down. It sounds like something may be grounding.
