System won't budge

When the power switch is turned on, the fan motors will move one quarter turn. No screen, nothing.

Sounds like a power on/power good signal fault. Could be the power supply or the mobo. The voltages can be read at the ATX connector: http://www.formfactors.org/developer\specs\ATX12V_1_3dg.pdf or you can try another if you have a spare power supply to verify whether it is a mobo problem or power supply. Also there are power supply testers but they cost almost as much as an inexpensive power supply. It's an easy replacement task. Steve Medley

Rockola download jukebox lights and screen do not turn on, but "insides" seem to be running ok. Screen says no video connection, then goes blank. Video cables are ok.


The lights inside most likely indicate it has power and is waiting for power button to be pressed. Could be as simple as power switch is failing.

Have an asrock 939sata2 I hit the power to turn on the led lights up along with the floppy drive light all the fans come on but that's it nothing else any solution?All the fan motors come on but t


Power Supply with a weak voltage power rail.

[There are 3 voltage power rails. 3.3 Volts, 5 Volts, and 12 Volts. All are DC Voltage ]

Enough power to light LED's, and spin fans, but not enough power to turn the Processor on.

1) If ALL of 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 can use 51 to 125 Watts of power.
Just depends on what Processor it is.

Suggest you check the three main voltages with a multimeter.
Since the Soft Power On circuit uses 5 Volts, I have a feeling the 5 Volt power rail may be the bad one.

An economical multimeter can be purchased for as little as $5 to $12.
Available in a multitude of stores. An auto parts store is but one example.
Need guidance in using it just post in a Comment.

Or you can borrow a KNOWN to be good, Compatible power supply, and use it for a test unit.

For additional questions please post in a Comment.

Cant get computer to


Disconnect everything from the motherboard except the power supply, CPU and power switch.

Turn on the computer. You should hear 3 beeps because you removed the memory.

If you don't hear any beeps, check the power supply. Check all the connections. Did you connect the 4 pin power? Did you skimp on it? A common mistake is to get a cheap, high-power supply. Just because the box says it's 1000 WATTs doesn't mean that will carry a steady load.

Still nothing...

It's either a bad motherboard or processor. If you have another processor that is supported on that board and you know it works, try it. If it boots return your CPU for a good one.

Unfortunatly, if it doesn't boot with a known-good processor that just proves the board is bad; it doesn't prove your CPU is good. You may have more issues.

Motherboard won't boot: no noise, no nothing...


Shorting the two leads will work but don't keep the two wires together. They are not ment to stay connected. Consider replacing your cases ATX power switch. Take a look at the link provided for a new switch;
http://www.cables4computer.com/Cases_and_Enclosures/Mid-Tower_PC-Cases_ATX_Push_Button_Power_Switch.html

The green LED on the motherboard means the board is in "Stand by mode". This green LED uses 5V DC to light the LED. After replacing your PS back into your system it may function just fine.

Good luck.

to sort out a hard ware issue.
Hope this helps
Have a nice day.

Your list of suspects:

1. Processor is cold dead.
2. Power Supply has got a problem. Just powering a fan is not a guarantee that it is powering everything normaly. Try a different one as you test agai.
3. I suspect your MoBo is good, but try a different video card also with your new DDR.
4. Do you hear the HDD cranking or whining when you turn on the PC? Keep ear near HDD and listen. It it whine-starts, it's a fair sign.
5. Try a different monitor while you test these.

Let us know what you find in clear detail.

Sounds like your memory.

How many sticks do you have in it?

Try removing all but 1, or moving that 1 around. You'll have to reset the bios and let it set without power for about 5minutes, between each try.

Do you hear any beeps at all? Do you have a system speaker on the motherboard? If not, plug a 2-pin system speakers onto the motherboard where it says "speaker" and listen for some beeps. You may have a fried CPU or dodgy RAM on your hands. Possibly even a faulty AGP/PCI-E slot, to name a few.
