Question about Biostar P4M800-M7A Motherboard

2 Answers

Pin Connection I am using a Biostar P4M800/8237 motherboard. After installing a new Video card, I noticed the cable that connects to my 9 in 1 card reader had pulled off the motherboard. I cannot find where it was connected. The connection is a 5 slot flat connector with 4 wires in it. Can anyone tell me where on the motherboard this connector goes?

It attaches to your choice of one of the two open and available USB sockets as I've circled in this image. Each USB socket has two horizontal rows of pins. A row with 5 pins. (the 5th extra pin is not used) A row with 4 pins. The first pin (on your left) is power, the last pin (on your right) is ground. ZT3000 "Beta tester of "0"s and "1's"

    Addition:

    I should add:
    Each row of horizontal pins in the socket corresponds to a single USB port.

    Looking at the image above, JUSB3 consists of two USB ports, the same with JUSB4.

Biostar Tpower x58 LGA1366 motherboard will not start or post


"I sent it for repair but it came back in the same condition!"

That means to me, spiritual_sky, that there is operator headspace.

Motherboard was fine when they tested it, and problem is on your end; Or they didn't test it, and shipped it back.

Going to go through the basics, so be patient. Mistakes are often made by those of us who are technically qualified, due to simple errors.

http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=390

A) The Support Plate the motherboard is mounted to, can be a separate plate, or is an integral part of the metal frame, of the computer case.

1) It looks as though there are 10 mounting 'holes'. (Manual gives no details. Looking at it right now. Going by Biostar Support page, and main view)

Is there a metal Standoff on the Support Plate, that does Not line up with the mounting holes? If so it is touching an exposed solder joint.
This = No

B) Have all the power cables needed connected to the motherboard?

1) 24-pin ATX main power cable. (Hooked end of Lock on power cable hooked over Tab on motherboard connector)

2) 8-pin EPS +12 Volt power cable.
Has 4 Yellow 12 Volt wires, and 4 Black ground wires,

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

Has a Lock on the power cable connector also, and Tab on the motherboard connector. When plugged in properly, and tightly, the hooked end is over the Tab.

Connects to Left Upper corner.

Not to be confused with an 8-pin PCI Express power cable,

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

[NOT an inference towards you, but I have seen people who could destroy a steel ball bearing in a sandbox, with a rubber mallet. They would try to cram an 8-pin PCI Express power cable, into a connector on the motherboard for an 8-pin EPS +12 Volt power cable ]

Three Yellow 12 Volt wires, FIVE Black ground wires.

A 6-pin PCI Express power cable will fit, and work, in a connector for an 8-pin EPS +12 Volt power cable.
Problem is it does -> Not, deliver the power that an 8-pin EPS +12 Volt power cable will deliver.

A graphics card senses whether a 6-pin, or an 8-pin power cable is being used.
SOME graphics cards will not work unless it is an 8-pin.

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

[See the power adapter cable on the right? Notice it uses TWO 4-pin standard Peripheral power cables. Some people make the mistake of only using one. This = NO ]

3) 4-pin standard Peripheral power cable. (Misnomered as a 'Molex' power cable)
Provides auxiliary power for the graphics card.
Manual states,
"This connector is an auxiliary power connection for graphics cards.
EXCLUSIVE power for the graphics card provides better graphics performance."

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

May be reaching here, but if the graphics card you are using does ->Not require an additional power cable connected directly to it, but does ->max out what the motherboard can provide, not connecting that additional 4-pin power cable may be the problem.

May need it even if the graphics card does have it's own power cable/s.

Graphics card requires a power cable? Better have it plugged in.
Requires TWO power cables? Better have two power cables plugged in, and Not just one.

Graphics has a problem? The motherboard will not start, or P.O.S.T.

Using a single Graphics card.
HAS to go in the PCI Express x16 slot next to the Northbridge chip, under the processor socket. (PEX16_1)

The PCI Express slot that is the same length at the bottom, is a
PCI Express x4 slot. This = No.

[Top slot next to Northbridge, {Copper finned Heatsink is on top of Northbridge chip},

PCI-Express x16 slot. Slot 1.
Next slot down is a PCI-Express x1 slot.
Next slot down is a PCI-Express x16 slot. It is Slot 2.
Next slot down is a PCI-Express x4 slot ]


C) Simple error; Front Panel header pinout.

Front Panel header (JPANEL1) is at the bottom right corner.
Pins 1 through 8 are on the Bottom row;
1, 2, 3, 4, 5, 6, 7, and 8.

Pins 9 through 16 are on the Top row;
9, 10, 11, 12, 13, 14, 15, and 16.

A) Pins 1, 2, 3, and 4 are for an Internal speaker. For BIOS Beep Codes. Pin 1 is for the Positive (+) wire. Pin 4 is for the Negative (-) wire.

B) Pins 5 and 6 are for the HarDDrive activity LED.
Pin 5 is for the Positive (+) wire.

C) Pins 7 and 8 are for a Reset switch, IF a Reset switch is used.

D) Pins 9 and 10 are N/C. Not connected. There is No Pin 11.

E) Pins 12, 13, and 14 are for a dual color Power On LED.
Pins 12 and 13 are for the Positive (+) wires, Pin 14 for the Negative.
If just using a single color Power ON LED, use Pins 12 and 14.

F) Pins 15 and 16 are for the Power On switch.

Make sure the Power On switch is good. Remove the wires, touch a Jewelers flat tipped screwdriver to the two pins - Briefly.

Comes on you have a bad Power On switch.

Do you KNOW that the Power Supply is good? Tested the three main voltages?
(3.3 Volt power rail
5 Volt power rail
12 Volt power rail )

Need to know how post in a Comment.

Just to ask; What is the maximum rated Wattage of the Power Supply, what is the Amperage of the 12 Volt power rail/s, and what is the manufacturer, and model number of the graphics card?

Regards,

I unplug my front audio connector cable and usb 2.0 connectors on my motherboard while putting in a new graphics card in the pci-e slot. After I inserted them back, my pc didn't want to switch on and I...


Uninstall the newly installed Graphics card and boot again. If it boots up normally, then the graphics card must be incompatible with your motherboard or might have some defect with it. Or if the system doesn't boot up even after the new graphics card is uninstalled, then you need to recheck the connectors and make sure everything is connected/inserted properly and fitted. The best way to check connection faulty is, plug-in one after another while you boot the system everytime... you plug in a connector. First connect the power switch and so on..

If you need further help, let me know.

Good luck.

My biostar g31 -m7 te motherboard does not boot when i try to add a msi rx800 pcie video card,,sometimes i get a overclock fail message after i remove the card and reboot,,,how do i get this card to work...


Turn the computer off.
Remove the PCI-E video-card.
Boot the computer.
Press DEL to "enter BIOS setup".
Disable the "onboard video" adapter,
or set the highest video-priority to be the PCI-E slot.
Save settings, but do not "exit" from BIOS setup.
Turn the computer off.
Install the PCI-E video-card.
Disconnect the video-cable from the onboard VGA-port,
and connect the video-cable to the new video-card.
Turn the computer on, and the video-output through the new video-card should be displayed on your monitor.

No Monitor display with P4VMA-M Motherboard cpu...


good day,

have you tried unplugging and replugging the cable connecting from the monitor to the video card? if after trying that it your video card is still not functioning, try installing a separate video card in its appropriate slot and try if this will work. better yet, have it checked by a competent technician in your area to verify other possible causes of this problem.

i hope this will help

You're board does not use an integrated graphics card.
Monitor does not have video display. There can only be four reasons why.
1. The monitor's video cable is not connected correctly at each end (Video card & Monitor) or cable is bad.
2. The monitor’s power cord is not plugged into a good power source or cable is bad.
3. The monitor may be bad.
4. * The AGP graphics card is either not seated correctly in its AGP slot, (remove/clean copper contacts with alcohol/allow to dry & reseat snuggly), or graphic's card is bad.
Monitor’s power cord can be switched with the PC's power cord.
The video cable & monitor can be swapped by borrowing from a friend.
(Just make sure their stuff is working first).
Never open the PC case without unplugging the power cord first.

Luck!
