Question about ASUS P5GD1-VM Motherboard

1 Answer

Motherboard detects nothing

Building new computer.  Everything set to factory settings.  Powered by 600 watt power supply.  Motherboard comes on, fans come on, DVD comes on if not plugged into motherboard only power, floppy light comes on.  Monitor remains in power saver mode, no keyboard lights, no mouse light.  I have been swapping out keyboards, mice and monitors all day.  Moved monitor from onboard to pci and back again - no luck.  Can't get into the bios because I can't see the screen.  I don't have a PCI express video card handy but have tried a PCI video card.  I am at a loss.  Any ideas? Other than go back to an AMD board? I have built dozens of AMD's; this is the first using Intel.

Re: motherboard detects nothing

Anniegms, I had the same problem with a new Asus board running a Dual Core Duo Quad processor. The boards BIOS was not updated to handle the Dual Core Duo yet. I had to switch processors to a P4. Use a different PC to make a BIOS update disk. Update the BIOS and switch processors back. But I had all the same symptoms of yours. However I did/do have a PCI-E XFX Fatality (Nvida) based graphics card. I would check or swap processors, it sounds like the board is waking up but not the processor. Just my thoughts.... PCdok

New build doesn't beep

A) Power Supply checks out?
You have tested the three main voltage power rails?
3.3 Volts
5 Volts
12 Volts?

What were the voltages?

Post back in a Comment.

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 (CPU) uses 51 to 125 Watts of power.
Just depends on what Processor it is.

AMD Sempron 100 series? 45 Watts
AMD Athlon II? Could be up to 95 Watts
AMD Phenom II? Could be up to 125 Watts.

Don't assume because you see LED's light up, and fans spin; that your Power Supply is good.

A Power Supply with a weak voltage power rail, will not have enough power to turn the Processor on.

B) The motherboard mounts to a Support Plate.
The Support Plate can be a separate metal plate, or an integral part of the computer case's metal frame.

Mounting of the motherboard to Support Plate, is accomplished with either plastic Spacers; or metal Standoff's.

If using metal Standoff's, make SURE all Standoff's are matched to a motherboard mounting hole.

IF, a Standoff is NOT matched to a motherboard mounting hole, there is a good chance it can touch the exposed solder joints; on the bottom of the motherboard.

Result? Short Circuit of motherboard.
MOST, of the time the 'offending' Standoff can be removed; or relocated, and the motherboard is OK.

C) All power cables from the Power Supply to motherboard, plugged in, and plugged in tightly?

New motherboard, and the connectors will be TIGHT, usually; when plugging things into it.

D) Disconnect everything except Processor, processor fan power, and Ram Memory.

Means unplug Harddrive power cable, and data cable.
Optical drive power cable and data cable
Card Reader cables, IF used.
USB Front Panel cables.
Computer case fans.

BARE minimum.
Turn the power supply on. (Press the Power on button)
You are at this point, just trying to see if you can get the BIOS Setup screen to come up.

(Press - enter BIOS Setup key)

BIOS Setup screen comes up, go on.
BIOS Setup screen does not come up, there is a problem with the motherboard.

BIOS Setup screen comes up, don't tarry around.
Turn the computer off.
(Press the Power On button in for a count of 10 seconds, or until computer turns off)

Computer case fans not plugged in, you don't want to overheat the motherboard chipset. (Especially the Northbridge chip)

Then add harddrive, and hook up computer case fans.
Everything looks good so far, then plug Card Reader in.
Then plug Front Panel USB cables in.
(The front of your computer is the Front Panel)

Had a person the other day find out it was his USB cables/USb ports; that were the problem.

E) By the way............
There are Solid Capacitors surrounding the Processor, and as you can see; other areas on the motherboard also.

However there are Electrolytic Capacitors on the motherboard too.

See them by the Northbridge chip, (Aluminum Heatsink is on it), and around the expansion slots? (PCI and PCI Express x1, and x16)
Around bottom of motherboard also?

The ones around the expansion slots I'm not that concerned about, as much as the ones around the Northbridge chip.

My belief is that the ones around the expansion slots, are used as Filters.

However the ones around the Northbridge chip, (And solids around the Processor), are used for Voltage Regulators.


Know what really bites?

Electrolytic Capacitors have Electrolytic Paste inside.
This is a chemical, and works with a chemical reaction.
It breaks down over time, also.

Can also just dry up inside, and show no outward visual signs of capacitor failure.

Plus, can I state this tactfully?
ECS motherboards are not known to be the 'cream of the crop', if you know what I mean.

For additional questions please post in a Comment.

N15232 motherboard wattage help

the power supply wattage rating is MAX wattage, not constant wattage. the power supply only outputs the amount of power that the rest of the computer calls for, and no more. if yor computer only needs 200 watts, that is all that will be sent from the power supply; even if it has a max rating of 600 watts, it will only send the amount of watts which your computer calls for.

Just bought a new motherboard and have hooked it back up nothing happens when powered up fans come on notheing else

1. You may have a power supply issue.
2. Try removing the power supply and replacing it with a know good one with the same specifications.
3. the power supply is giving the +12 volt to the fans but not to the rest of the board.

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.

New build computer wont turn on (ASUS A8N32-SLI Deluxe Socket 939)

The ATX power supply needs to have pin16(PS_On#) to be connected to COM for it to work. When you press the power switch on the front panel of the computer, you are essentially making this connection. Check that the cable from the power supply to the motherboard is making good connection. You can verify operation of the power supply by shorting Pin16 to pin17 on the powersupply output, with a paper clip. Pin16 is usually a green wire and 17 is black. Hope this helps. -Vish

Mach speed motherboard problem

I had the same problem once. I took it to CompUSA to have them diagnose the problem, and they said I fried the motherboard or CPU. The fans turn on just because your power supply is on.

Help needed.....

Hi Octane, If you?re not getting any beep codes then something real basic is wrong. To start off I would check the following: -check the new power supply and ensure it is designed for your motherboard. -check the power supply connections to the motherboard, the connectors should mate up exactly to the motherboard connector. -check for shorts (mounting screws against capacitor leads are common), correct grounding and so on. Any of those can cause the same symptoms. -test the power supply in another computer or if not available you can generally pickup an inexpensive tester for $10 to $15 at a computer store that sells parts. -make sure your motherboard is designed to accommodate your processor. I would expect a beep code for this but you never know. Let us know how things go and please don?t forget to rate the posting.
