Question about Biostar P4M80-M4 Motherboard

3 Answers

Biostar motherboard or processor dead?

Thanks for info. However, I tried a good power supply but its the same problem. When I turn on power only fans (CPU and case - both plug directly to motherboard) spins. No other sounds. Also floppy drive light comes on immediately and stays on (and floppy cable is plugged correctly). I want to think it may be the motherboard or processor. Any other ideas?

Your CPU might be overheating, and the system is shutting down.
I just went thru this with my computer (same mobo).
No messages or beeps, just yellow light on front of case.
In my case the dust built up enough to hamper cooling.
Make sure you vacuum & blow out any dust inside.


Hope this helps.

Unplug hard drive, no beeps? Unplug CD-ROM, no beeps? Remove RAM, no beeps? 85% it's the MOBO. Static, surge or just plain dead (and cheap).

It isn't a guessing game, Dave.

Suggest use a Power Supply Wattage Calculator, and be SURE,

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

Need guidance in using either one, post back in a Comment.

Need all the specs. (Motherboard, {Biostar}, Processor, Ram Memory, graphics card (IF used), how many fans, how many optical drives, (CD/DVD drive), etc.

Mainboard: g31 m7 te - power: antec hcg750 - gpu: gtx560ti


No the mobo is compatible with the Power Supply, and GPU.
And vice-versa.

Mainboard fan???????
You mean the Processor (CPU) fan?

I'm guessing I guess, because computer case fans aren't on the motherboard/mainboard/mobo.
(MOtherBOard)

You're getting power to the mobo, but the question is how much?

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 from 51 to 125 Watts of power.
Just depends on what Processor it is.

http://206.108.48.60/app/en/mb/introduction.php?S_ID=363&tab=1

The mobo will support Intel Core2 Quad-Core processors. Depending on which one, you may be talking about Up To 105 Watts of power,

http://en.wikipedia.org/wiki/List_of_Intel_Core_2_microprocessors#Quad-Core_Desktop_processors

This is why LED's can light, and fans may spin, but the Processor isn't getting enough power, so the computer will not turn on. (Processor isn't turning on)

Why?

1) Just because that Power Supply is new, doesn't mean it is good.
Sometimes you get a bad one. Test the three main voltages coming out, with a multimeter set to DC Voltage.

Need guidance post back in a Comment.
(An economical multimeter can be purchased, for as little as $8 to $12. I have seen cheaper. Available in a multitude of stores. An auto parts store is but one example )

2) You don't have the 4-pin ATX +12 Volt power cable plugged in.
Goes to the white square 4-socket hole connector, to the left top corner of the Processor socket.
(Motherboard installed in computer case)

3) REQUIRES -> TWO 6-pin PCI-Express power cables, for the Nvidia GTX560Ti graphics card.

The Antec HCG750 PSU has 4 of them, so no problem there, IF you have two of them plugged into the graphics card.

Both connectors of the 20 + 4-pin ATX main power cable's connector, need to be used. Biostar mobo requires a 24-pin ATX main power cable.

Sounds like something like your ram or processor are no good yet.
If it doesn't give any kind of beep, start over, with just ram and processor, and keyboard.

No noise, no beeps whatsoever?
If no beeps, MBoard may be defective, or RAM might be bad, maybe one of the drives.
You need to d differential diagnosis.
Try removing everything but the CPU and see if it will POST.
If so, add 1 stick RAM, then 2nd stick, then Drive, then ,,,,,, until you find culprit.
If nothing works, would try another "known good" power supply
If that is no go, Mboard bad.

Hello I have a problem, my motherboard g31-m7 no video, i picked up the battery, but the problem still there, how to solve this problem?


I don't know who recommended a CMOS battery to fix your graphics, but this = no.

1) You have checked the monitor cable, correct? If the monitor cable is removable, replace it with a known to be good one, for a test.
If the monitor cable is not removable, use a known to be good monitor, and cable for a test.

2) If you are using the Integrated Graphics of the motherboard, (OnBoard graphics), then the next test is to install a graphics card. If you have graphics now, your OnBoard (Integrated) graphics chipset is bad.

3) I find most of the time, (Like around 80% or more) that the Power Supply is bad.
Enough power to light LED lights, spin fans, (Or spin a few times, and stop), but NOT enough power to turn the Processor on.

A bad Power Supply is one of the leading causes of computer failure, right next to computer is dirty inside.

A) ALL of the LED lights being on at once, will use less than 1 Watt of power.

B) EACH fan uses 2 to 3 Watts of power.

C) A typical Processor can use 51 to 125 Watts of power. Depends on what Processor it is.

Here you can see a CPU Support list for the Biostar G31-M7-TE motherboard, and the wattage of the different CPU's,

http://www.biostar.com.tw/app/en/mb/cpu_support.php?S_ID=363

Again, you may have a bad Power Supply.
Enough power to light LED lights, and spin fans, but not enough power to turn the Processor on.

No Processor operating, No computer.
No computer operating, No video signal.
(No Signal)

Do you have a KNOWN to be good, compatible power supply to use for a test unit?

NEW BIOSTAR MOTHERBOARD DOES NOT BOOT


Good day sir, let try to test first the power supply, Unplug the power cord, remove the 20 pin (24 pin for the late model) molex power connector from the motherboard, plug in the power cord, get a 2 to 4 inch jumper wire, short the green wire with any of the red or black wire on the molex 20 pin power plug, the result maybe the following:
  1. you will see the power supply fan turn. you power supply is in good order. replug the power supply, and test again.
  2. you will see the fan turn for a few second then stops. you power supply is selective, and may require a different type of motherboard. Get a new one.
  3. you wont see the fan turn at all. get a new one.
If in case you are with #1. uinplug the power cord and remove all the expansion cards, data cables from the hard disk and cd drives. we are trying to isolate the problem. make sure that the only connected cables on the motherboard are as follows:
  1. 20 pin power cable.
  2. 4 pin 12 volt power cable (if applicable)
  3. speaker
  4. power switch
  5. power led
Test the pc once more. plug in the PC. If still the board wont power on. problem with your motherboard. Note:make sure your RAM is good. Hope this helps.

Mother board reset buttom?


I assume you have the fan of your power supply working indicating that power is OK.

Disconnect everything from the motherboard leaving only the processor, fan and power. If you don't hear any beep means that you have a problem with either the motherboard or the processor.

PS Verify compatibility of motherboard FSB and processor.
