Question about Asrock P4VM8 Motherboard

1 Answer

I just bought a new Motherboard and processor for my old computer, i also bought a new power supply as well. I mounted the processor with the heatsink and plugged everything in as the instructions had specified. I went to turn the computer on and had not gotton any sign of life. The fan did not spin. The hard drive did not start to spin as well. But the power light for the systems LED came on and I replaced the 3v 2032 battery. I also jumped between two motherboards and three different power supplies. any suggestions?

Did you plug in the video?

Did you plug in a HDD?

    then you might have to send it back and ask for a replacement, because its their fault if the shipping destroyed it.

PC runs for about 10 seconds then powers off

A) The first thing to check is the Power Supply.

Cannot depend on LED's lighting, or fans spinning; to include the Power Supply fan.

A Power Supply with a weak voltage power rail, will have enough power to light those simpy LED's, and maybe spin fans; but NOT enough power to turn the Processor (CPU) on.

1) If ALL of those LED's (Light Emitting Diode), were on at once; they would use less than 1 Watt of power.

2) EACH fan uses about 2 to 3 Watts.

3) A typical CPU (Processor) can use 51 to 130 Watts. Just depends on what Processor it is.

(Not trying to slam your motherboard Chris, but $219 bucks?
You couldn't GIVE me that motherboard..........jus sayin')

Uses the Intel 865G motherboard chipset,

Scroll down a little

Can use Processors that need Up To 115 Watts. (Maybe higher)

Did you test the 3 Main voltage power rails?
3.3 Volts (DC), 5 Volts (DC), and 12 Volts (DC)
What were the voltages?

Or did you use a KNOWN to be good, Compatible power supply?
How do you know it's good?

Moving on..........

B) I suppose an inspection of the Electrolytic Capacitors, should really be first. It is a visual inspection,

However, you have replaced the motherboard. So we in good faith, have to assume the motherboard is good........(Or do we?)

This would lead to the Thermal Paste, on top of the CPU (Processor), has dried out.

Top of CPU, and bottom of finned Heatsink needs to be THOROUGHLY cleaned, and fresh, new Thermal Paste applied.

C) No? Power Supply has been deemed to be good?
Processor and bottom of Heatsink cleaned, fresh new Thermal Paste applied?

(4-pin ATX +12 Volt wire plugged into motherboard?
Power for the Processor, )

......The motherboard is mounted to a Support Plate.
The Support Plate can be a separate sheet of metal, or an integral part of the motherboard.

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

IF, a Standoff is NOT mounted to a motherboard mounting hole, and is just standing out there; there is a good chance it will touch one of the exposed solder joints, on the bottom of the motherboard; and short the motherboard out.

Removing the 'offending' Standoff, or moving to an open motherboard mounting hole; may result in the motherboard working again.

Along with the Standoff's are Fiber Washers.
Rule of thumb is;

Motherboard mounting hole has metal ring around it? No fiber washers are used.
Motherboard mounting hole does NOT have a metal ring around it?
Fiber washer is used on both sides of motherboard mounting hole.

Let's consult the Intel D865BGF Product Guide,

Doesn't say.
Statement is, "Refer to your chassis manual for instructions on installing and removing the desktop board."

Motherboard may get it's ground, from those metal ringed motherboard mounting holes. IF PRESENT.

D) Motherboard is bad.
Electrolytic Capacitors are bad. If they do not show outward signs of failure, the Electrolytic Paste inside could be dried up. Would show no outward signs of failure.

Computer design engineers know this. They know the Electrolytic Paste inside is a chemical, and has a chemical reaction.
The chemical breaks down over time.

This is why computer design engineers use Electrolytic Capacitors, that are rated at TWICE of what is needed.
When the capacitor breaks down to 50 percent good, it is still 100 percent good for the application.

Now...................New/Old Stock, or not; that mobo is OLD.

E) Processor (CPU)
Very rarely one goes out. Overclocking, and getting it too hot?
Oh yeah. Bye-bye CPU.

There is one other way, though.........

A CPU (Processor) is the MOST, susceptible hardware component to Static shock.

If whoever has been handling it has not followed Anti-Static Procedures, drill a hole through it, and put a chain through the hole.
See? You've got a snazzy(?) necklace......

Motherboard can be used for a Frisbee, too.

F) Are you running a graphics card?
Power Supply has enough power for it, and the rest of the computer system?
Motherboard, Ram Memory, Case fans, CPU fan, optical drives (CD/DVD drive), and Harddrive/s.

G) IF, the graphics card requires a power cable, does your Power Supply have the necessary power cable?

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.

1 beep then shuts off

Hmmm, one beep is good! lol!

Means P.O.S.T. is good.

I see we're working with an AMD processor, and a Socket 462 (Socket A), motherboard.

Let's look at some basic installation problems for that motherboard, and see if any fit;

1) Since it is an AMD processor motherboard, you have to be SURE that Thermal Paste has been applied PROPERLY, and applied.

An AMD processor runs hot, for the models that fit that motherboard.
If no Thermal Paste has been applied, the AMD processor could have burned up.

2) Anti-Static Precautions:
I know, I know. But you would be surprised with those of us, who do not know what Anti-Static Precautions are; and work on computers.
(Hmmm, wonder why it doesn't work? Must be a bad motherboard)

3) Mounting to the Support Plate.

The Support Plate can be a separate metal plate; or is part of the computer case.
Mounting of the motherboard to Support Plate can be done with plastic Spacers; or metal Standoff's.

(Standoff. Shapes vary a little, but basically; 3/8ths to 1/2 inch long, hex shaped, threaded shaft on one end; and a threaded hole on the other end)

If a Standoff is NOT mounted to a motherboard mounting hole; and is just sitting out there on the Support Plate; it can touch exposed solder joints on the bottom of the motherboard, and cause a Short Circuit.

MOST of the time if the 'offending' Standoff is removed; or placed where it should be, (Motherboard mounting hole), then the motherboard, etc may be OK.

4) Power Supply:

If the Power Supply was on it's last leg, this may be the 'straw that broke the camel's back'. Power Supply went to the Power Supply graveyard in the sky.

If the Power Supply does not have enough power (Wattage, and Amp's), then you would also see the problem you stated.

New Power Supply, or old? What is the manufacturer, and model number?

How to build a or assemble a computer and troubleshoot?

Building a computer will require: a motherboard, a processor, memory, a video card or motherboard with onboard video, a sound card or motherboard with onboard sound, at least one hard drive, a CD or DVD drive, a case for the computer components, a power supply, fans to cool the computer, an operating system, a monitor, speakers, keyboard, mouse, 2-3 hours to assemble the computer.
You must ensure that all of the components are compatible with one another. After receiving the parts, lay everything out on a large, clean surface. Make sure you are grounded by touching a metal surface; this will prevent the transfer of static electricity to your computer components.
Typically, the steps to install the components are as follows: 1. mount the power supply in the case, 2. mount the motherboard 3. lock the processor in the socket on the motherboard 4. insert the memory sticks into the slots on the motherboard 5. mount the processor fan on the processor 6. insert the video card into the applicable slot on the motherboard 7. insert the hard drive into a hard drive bay in the case, 8. insert the CD drive into a CD drive bay, 9. mount any fans you have to the fan cutouts on the case 10. connect all applicable data cables to the CD and hard drives 11. connect all applicable power cables to the motherboard, video card, processor, hard drive, CD drive, and any other components. 12. connect the front panel USB, power, lights, and reset connectors to the motherboard 13. close the case 14. connect the power, monitor, speakers, keyboard, and mouse to the computer
Because this process is rather involved, I recommend following a guide such as this one:
It details the process, includes pictures, and even provides a list of compatible parts.

I have an old computer with L4SMG/651+ motherboard. Power supply is good(checked w/a checker), but the fan works slow. Fan mount for the CPU is broken on one clip, the heat sink sits flat, but the fan sits...

That mount, sits the entire HEAT SiNK for ur processor, if it is broken the heat sink will not flatly sits on ur procie and helps out the HEAT it produces!

If u have another desktop, just try to pull out the old Hard disk and make it ur slave for ur NEW desktop, to get the data and files u wanted from that old one!

HI ! I bought a new AMD phenom quad-core 9750 2.40ghz processor and Gigabyte motherboard. I m unable to install Windows and the system automatically shuts down every 20 min and sometimes runs for more...

This processor need better cooling system as it is powerful it need more power so I suggest you to upgrade your Power Supply and buy more efficient processor fan cooler. Also you should check if processor is properly installed on motherboard and there should be some special thermal grease between processor and motherboard ( for better thermal conductivity

Just brought new memory for my acer aspire sa90 desktop,now my computer doesn't seem to turn on

i assume computer was starting correctly before? this is older computer and it is using sdram memory, locket on them sometime do not clip in correctly.

1. switch off computer
2. remove power cord
3. remove side wall
4. remove sdram
5. check sdram orientation and type, if they correctly align with registering notches
6. release lockets to max, (outward from slot)
7. re-insert correctly oriented sdram till lockets close into sdram stick (you may give them bit "help" to close in position)
8. re-connect power
9. start computer

if copmuter start normally, that meant tha tyou fixed the problem, if not, switch computer off and remove power cable, check motherboard power cable insertion, and repower again.

if computer start, lose cable was the problem.

if computer still do not start, remove new memory and re-nstall old one, if computer start, new memory will be a culprit.

if computer no fan "jig" and no light blink, remove all power supply cables from motherboard and connect in it's place new power supply, to exclude power supply problem.

if computer start with new power supply, old power supply will be the problem,

if computer do not start, and no joy with checking, but fan is running, including on the processor, this will indicate either, motherboard or processor died... if that is the case further testing will be required to determine which is exact cause. as in home situation there are usually no motherboard testing equipment, you need to go to more difficult path of changing the processor, checking video and haveing second computer on which you can test all of that...

replacement board for that processor on ebay cost from about $0.99 plus postage. if you need any further advice, please re-post adn if i am on line today, i will provide you with further procedure how to test your video, motherboard and processor.

if you find my advice useful, please do not hesitate to leave your comment and vote 4 for me, thanx!

I just bought a new motherboard; basically new everything, well on my old motherboard there was a CPU and on this newer better motherboard there is not a CPU. Do I need to got one? What is a CPU exactly?

first, make sure that the new mother board support the old Processors, ask the M.Board supplier about it (or google it) , and make sure you know the old processors type.If you wasn't really sure, just remove the old Processor from old M.Board, then check for the ID (such as Pentium 4, Pentium D, etc ) on top of the processor.

If the new M.Board support the Processors, then you can re use the old processors, if don't, then you don't have a choice, buy the new one that match with the new M.Board specifications.

Hope you understand.

Installed new Power supply, Monitor stays in standby...? So I noticed my fan was starting to go out, then it actually went out, my power supply would start to over heat and the cpu would shut itself...

Your problem is either the processor or the motherboard. that is why your monitor is not getting any signal. first try to replace the processor because I suspect that this might be the problem as it has gotten overheated before. if there was a power problem with you power supply you monitor would not power up at all.

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.
