P4M2PROP motherboard have power but not working???

Disconnect the power cord form the power supply, be sure the power supply is set for 110 or 220 volts depending on your location and power and double check it (most have a 110/220 switch)

Feel/look at the back of the power supply to determine if the fan is working.

If the fan is working, try another power supply anyway.

Plug the computer directly into a known-good (a lamp works) power outlet

Check to be sure you do not have a motherboard stand-off in the wrong position and shorting-out the bottom of the motherboard.

Inspect/shake and listen for loose metallic objects (loose screws) on top of and under the motherboard and in expansion board slots.

Look carefully at the ISA and PCI slots, see if any of the contacts got bent/shorted-out.

Sometimes an expansion board will dislodge one and it will be pushed into the bottom of the slot.

Inspect the motherboard for broken or burnt components.

Carefully inspect the motherboard for black soot from bad bearings and clean and replace the culprit.

Look for bent/shorted pins on the motherboard headers and straighten.

Be sure the speaker is plugged into the motherboard.

If you hear beeps.

Decode the beep code.

If not, double-check all jumpers.

Push down on all chips that have sockets in attempt to reseat them.

What CPU are you using?

Be sure the core voltage is correct.

Be sure the CMOS battery jumper is in the correct position.

Some distributors purposely ship motherboards with the jumper in the wrong position.

Find the jumper that clears the CMOS, put it into the clear position for several minutes, put it back in the normal position, plug-in the power cord, and push the power-on button.

If you apply power to the motherboard with the jumper in the clear position you may damage the motherboard.

Pull all boards except video.

Disconnect all cables going to all drives, pull all cables except power, power on, and speaker, connect the power supply to the motherboard

(the black wires go in the middle on AT power supply connectors--"Black OK, red your dead"), reseat the memory, plug-in and screw-down the display adapter and nothing else

(push down on the top, front of the adapter and make sure it is properly seated by looking at it all along the PCI or AGP connector), connect the power-on switch and the speaker.

Check the monitor plug for bent or pushed-in pins, connect the monitor and nothing else. Check the monitor power cable.

Reseat/replace the memory.

Check for Motherboard Electrolytic Capacitor Failures

Check the CPU for bent pins.

Try another processor. Note: If you apply power to a motherboard with an Athlon or

Duron processor without the CPU fan connected, even for a few seconds, you will fry it (see http://duxcw.com/digest/guides/cpu/socketa/heattip.html).

Check the CMOS battery with a multi-meter. Should be around 3 volts (2.8 is ok).

Try a different video board.

See if the CPU and memory will work with another motherboard.

Pull the motherboard, set it on the box it came in, install video, memory, CPU, power, and power on.

See if it boots.

I have seen several instances where this works when the board will not work in the case.

And, when reinstalled in the case, it continues to work.

I have also seen where it didn't work out of the case immediately, but did work the next day and continued to work.

One of those mysteries.

Temperamental computers with minds of there own.

Replace the motherboard.

hope this helps

1st try to change power supply (if you have a spare one). If this dowsn't work remove device by device (HDD, DVD etc) until You get some results. If fan on cpu is not working it power unit or MB error

hello,
if Motherboard is OK you can also check the capacitors on that motherboard if there is nothing that is swollen or burned , check the power supply if it is working as well, or get a known good power supply, you can use, check the front panel for the power switch if it is working as well.. also make sure that there is noting connected to the motherboard like USB, printer, cam and hard disk.. power on w/ known good power supply, memory, video card, try if it will work...
thank for using fixya.

Have you checked the power supply in different system? If yes then first replace CMOS battery and switch the CMOS battery jumper. And while doing this please unplug the hard disk or optical drive data cables and power. If it does not work then check the power switch is working or not or it is perfectly connected with the front panel PINS on the motherboard. If it is not connected perfectly computer will not start after pressing power button.
Second Level Test : Remove the CPU Fan - replace the CPU perfectly - again place the Fan.

Third Level (motherboard test): Just take the motherboard removing CPU,RAM, SMPS - use another same type CPU, RAM and SMPS - if it does not work so it is motherboard problem. If it works may be CPU problem.

Try to check your CPU unit it maybe have a power when you turn it on. Or just check their power suppy at the back when it works. If you check that all and it works normal just check inside your computer and try to see the Power LED (Light Emiting Diode) of the motherboard if have a light. Because if it is have a light your motherboard is good and if it is no light in the Power LED of the motherboard that was damage. But if your motherboard does not have installed Power LED try to check the CPU Fan it maybe works properly it because the CPU Fan was conncected in the motherboard if did not works the motherboard is also damage and need to replace. But if the CPU Fan was working properly, try to hold the CPU Heatsink if it is very hot the damage is your micro processor.

First of all you check the power supply. Is it working proper the you check the power cable which put on the motherboard. sometimes this cable disjoint . you press the connector. and then check . hope this will work.

Check if the power supply is working. If it does not working then it is the power supply. Change the motherboard power supply.

NO POWER.

Switching power supplies (the most common used PC's), cannot be adequately field-tested with V/OHM meters. Remember: for most switching power supplies to work, a FLOPPY and at least 1 meg of memory must be present on the motherboard. If the necessary components are present on the motherboard and there is no power:
1) check the power cable to the wall and that the wall socket is working. (You'd be surprised!)
2) swap power supply with one that is known to work.
3) if the system still doesn't work, check for fuses on the motherboard. If there are none, you must replace the motherboard.

thanks

hi this is parveen

solutiom for d845gvsr not poweringup only led flashing--

short pin 92 and 93 of smsc LPC47M172 with fine tip soldering iron .
pin 92 is nrsmrst signal that is 3.3v at time of working m/b when this signal is low than motherboard not powering up so we short pin 93 that is standby (3.3v) and motherboard powering up again and working properly this problem doesn,t come again in future. this solution is 98% working 2% chances to change the chip.

it seems so
