Question about PC Chips MB PCCHIPS SiS746FX M848A V5.0 462 Motherboard

1 Answer

Cant get Motherboard to boot

I bpought a PCChip M848 V5.0 Socket 462 ATX M/B. As well as a new power supply I believe 320 Watts. I set up all the attachment internals: HD, FDD IDE AGP ATI Video Card with CD/ DVD one mastered and ther slaved. I cant get past CMOS. It shuts the video part out completely. I took all of the internals out with the exception of just the HD to eliminate and other device causing the problem. This is the second MB of the same brand. Ive done everything the book ask you to do like clearing CMOS and seting the Optimal settings but this still doesn't solve the problem. I have change the Vidoe card from agp to PCI as well as the Video just to see if the last two would be the problem but to no avail. Any Answers for this mess?

Hello here is the homepage:

http://www.asus.com/Motherboard/M3NHDHDMI/#support_Download

Your power supply is probably failing, or to small for the system.

Are all drivers and the bios upgraded ???

If you are useing the onboard graphic, try to add a better graphic card on the mainboard for better performance.

I suggest you to buy a 500 watts power supply, or bigger depending on the systems specs.

Good luck

New GA-990AX-UD3 motherboard will not boot


You really should take that Power Supply, and use it on grandma's computer.

The 8-pin EPS +12 Volt power cable was brought out, to provide more power To the motherboard AND processor.

http://www.playtool.com/pages/psuconnectors/connectors.html#eps8

The 4-pin ATX +12 Volt power cable has TWO yellow wires.
Yellow wires are 12 Volt wires. (And two Black ground wires)

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

The 8-pin EPS +12 Volt power cable has FOUR 12 Volt wires.

In the motherboard manual, does it say, "Yes Tom. Go ahead and use a 4-pin ATX +12 Volt power cable. We don't care. We just use an 8-pin EPS for fun."

[ This is an 8-pin PCI Express power cable. Completely different,

http://www.playtool.com/pages/psuconnectors/connectors.html#pciexpress8 ]

The motherboard probably uses 150 Watts by itself.
No Ram Memory, no CPU, no fans, etc.

The CPU could use up to 125 Watts of power. Just depends on what AMD, socket AM3, processor you are using.

Now to graphics card's power;
The most Wattage a PCI-Express x16 slot can deliver is 75 Watts.

The most power a 6-pin PCI Express power cable can deliver is 75 Watts.
8-pin EPS +12 Volt power cable? 150 Watts.

When buying a Power Supply you should calculate all components needing power,

http://extreme.outervision.com/psucalculatorlite.jsp

,then buy a Power Supply that has AT LEAST 10 percent more power than needed. Easier on the Power Supply.
Also a computer will NOT use more power than it needs.

10,000 Watt power supply, (Exaggeration ), and the computer only needs about 100 Watts for surfing the internet?

Computer ONLY uses 100 Watts.

Due to the price, the above, and the availability, you should use a 500 Watt power supply at least.

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=899123&CatId=1079

http://www.amazon.com/StarTech-6in-Pin-Power-Adapter/dp/B002O21XHQ

Or use it on yours if it has enough Wattage.

Back in the day, the motherboard didn't need to supply that much power to components on it.
More powerful Processors, Ram Memory, and graphics cards, brought the power needed, up.

A 4-pin ATX +12 Volt power cable was added for the motherboard. Then 6-pin PCI Express power cable for graphics cards. Then the 8-pin PCI Express power cable for graphics cards. Lastly the 8-pin EPS +12 Volt power cable.

(Better make sure the Power Supply you have is good, if you wish to use the above power adapter cable. Nothing like having a Power Supply with a weak voltage power rail, and a new build, to pull your hair out on )

http://www.gigabyte.com/products/product-page.aspx?pid=3894#ov


Out of the motherboard manual Page 23,

"With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design.

Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start.

To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system."

Can't get my hp pavilion a 1340 n to power up even after I tried a different power cable


See if the problem is the Power On switch, or the Power Supply.
Bypass the Power On switch.

If the computer (Power Supply) comes on, you have a bad Power On switch.
If the computer (Power Supply) does NOT come on, you have a bad Power Supply.

The ECS RC-410M motherboard uses a 24-pin ATX main power cable.
(Elitegroup Computer Systems)

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00590356&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=1818054

Scroll down the page to the motherboard illustration and photo.
On the right side is ATXPWR1.
(To the right of the Ram Memory slots, DIMM 1 and DIMM 2)

This is the 24-pin ATX main power cable connector on the motherboard.
In the photo it's above the blue IDE1 connector, and to the right of the black Ram Memory slots.

This is a general example of a 24-pin ATX main power cable, and it's respective connector on the motherboard,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The BACK of the connector is where the wires go in, as shown in the photo to the far right.
The FRONT of the connector is shown in the middle photo.

With the computer plugged into power, and the ATX main power cable plugged into the motherboard, as shown in the far right photo, a jumper wire is used to touch the Green wire, and ANY Black wire.

The Green wire is the Soft Power On wire. Abbreviated as PS_ON.
ANY Black wire is a Ground wire.

The preferred jumper wire used is a paper clip. The paper clip is straightened out, then bent into a U-shape.
The top of the U is wrapped with black electrical tape for your fingers. (And thumb)

One 'leg' of the paper clip goes down into the socket hole with the Green wire.
The other 'leg' goes down into a socket hole with ANY Black wire.

The leg of the paper clip is inserted down into the socket hole, RIGHT NEXT TO THE EXISTING wire in the socket hole.
The diameter size of the paper clip allows this.

Looking at the middle photo you see metal contact sockets. These are female terminal contacts. They resemble tubes.

The wire's insulation goes pretty far down into the back of the connector. This means the leg of the paper clip needs to go far enough down in the socket hole, to ensure that it touches the metal terminal end.

Touch briefly. No more than 2 seconds.

There may, or may not, be a spark made when the jumper wire makes contact.
The voltage is 5 Volts DC.
In comparison two D cell flashlight batteries produce 3 Volts DC.

The plastic Power On button assembly has an ATX power on switch inside it.
A momentary contact switch.

This is one example of an ATX Power On switch,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

The Power Supply is just the usual ATX style. Maximum rated wattage is 300 Watts.
Actual maximum wattage is probably more like 70 percent of that.
210 Watts.

{Note*
A computer only uses the power it needs, and NO more.
If the computer only needs 100 Watts for what it is doing, it ONLY uses 100 Watts.
(Surfing the internet, for example)


If you get a good deal on an ATX power supply with more than 300 Watts, get it.
It will not hurt the computer.
Always purchase a Power Supply that has at least 10 percent more power than needed }

As long as it is an ATX compatible power supply increasing the available wattage is not an issue, only meeting MIMIMUM power requirements
You can go to a 500, or even a 750 as long as it has the correct motherboard connections

My computer just stoped working. It wont power on and when I hold the power button there is just a blue flashing light


Bad Power Supply.
Weak Voltage power rail.

The Pavilion a6000n desktop computer uses an ATX style of power supply, and is rated at 300 Watts.
(Probably made by Delta Electronics)

The ATX style of Power Supply is used in over 85 percent of PC's. Very common unit.

[Case size is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall ]

What you are looking for is an ATX power supply with at Least 300 Watts, and the correct power cables.

Note that a computer only uses the power it needs, and No more.

Wouldn't matter if you had a 10,000 Watt Power Supply, (Exaggeration), and the computer only needed 100 Watts, it will only use 100 Watts.

(Surfing the internet typically uses 100 Watts.
Computer. Monitor uses it's own power, and is separate from this figure)

This is HP Support > Pavilion a6000n desktop computer > Specifications,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00873231&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3377269&lang=en

This is HP Support > Pavilion a6000 desktop computer > Motherboard Specifications,

1) Scrolling down the page, and looking at the photo of the motherboard, you can tell the Power Supply must have a 24-pin ATX main power cable.

To the right of the Blue, and Black ram memory slots is the 24-pin ATX main power cable connector, on the motherboard.

It is White in color, and consists of 2 rows of 12 socket holes.
24 total.

On the illustration it is marked as - ATXPOWER.

This is a closer look at a typical 24-pin ATX main power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atxmain24

Note the Lock on the side of the connector. The Lock is hinged in the middle, (Plastic), and operates like a see-saw on a playground.

Squeeze the top of the Lock in to remove the 24-pin ATX main power cable.
ONLY gently pull up on the connector, and NOT the wires.

[This action brings the hooked end of the Lock away from a 'Bump', or protrusion, that is present on the female connector, on the motherboard ]

2) The Power Supply must also have a 4-pin ATX +12 Volt power cable.

On the illustration where it states Socket AM2 is the Processor socket.

To the left, and down a little of the Processor socket, is a blank square.
The writing under it is illegible.

This is where the 4-pin ATX +12 Volt power cable plugs in.

On the motherboard photo it is to the left of the white Processor socket, and is square in shape, with four socket holes.

This is a better look at a 4-pin ATX +12 Volt power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#atx12v4

Color of the plastic used in the connectors, does not matter.

3) Looking at the Specifications page, you will see that the Power Supply must have at least 1 SATA power cable.
It's used for the 250GB SATA harddrive.

Closer look at a SATA power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#sata

NOTE*
If the SATA harddrive in your computer has a place for a SATA power cable, and a 4-pin Peripheral power cable, ONLY use the SATA power cable.
DO NOT use both.

4) Again looking at the Specifications page, the Power Supply must have at least two, 4-pin Peripheral power cables.
Used for the optical drives.
(DVD drives)

A closer look at a 4-pin Peripheral power cable, and it's respective connector,

http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral

There may be more 4-pin Peripheral power cables needed, to run any computer case fans.

[The Processor fan plugs into the motherboard ]

An example of an ATX power supply that is 500 Watt rated, and has the correct amount of power cables, plus the correct type of power cables,

Fic k7mnf-64 motherboard socket 462 amd 3000+ When I plug the computer in all that happens is a red light on the board comes on and a buzzer goes off.


Power is not going to the board. Check the power supply cables going to the board; most use a big 20 pin connector & a 2nd 4 pin connector. Make sure both are plugged into the proper spots then retry boot. Should see a green light on motherboard if power is properly set up. Hope this helps.

My first PC build....gone horribly wrong =(


Hi,

Please CLICK HERE for more info on your power supply.
My guess is that your power supply is dead. If the fan doesn't spin it may be that the fan died first and the PSU overheated.
Now, if you are fortunate nothing else got damaged. You can remove the PSU (the mounting screws are on the back of the case, there should be four) and buy a new one at your friendly local computer parts store. Get one rated for at least as much power as the old one. We can give you a hand on this if you tell us what the lable on the side of the PSU says.
I should caution you that there is a chance that when the PSU went it damaged other parts of your system.

Goodluck..

Hi, one quick thing you can check is to see if the cable running from the power switch is plugged onto the right pins on the motherboard, it will most likerly say (pwr btn) next to the pins or something like that, it may also need to be a certain way round.Let me know what the outcome is if no good we can try something else. hope this has helped.
