Remove the CPU from the motherboard. (A pain in the rump).
Double check the CPU pins. (Many) Make sure they are not bent or missing pins. (If any are broken than the CPU is finished, it can not be fixed. Replace the CPU). If ok, reseat CPU & make sure CPU slides gently into the socket. (If you have to push it in the socket, than it is not lined up correctly). You can see how to install a CPU by opening this link. (Though this CPU may not be the CPU as your's this is how to install one).

If this has helped, great! If not please explain what I am missing so I can help you find the correct method/answer to fix this.

Show all solution to d945plrn motherboard problem not powering up


PSU IS OK? You're sure? You tested the 3 main voltages coming out?

DON'T rely on; "The LED lights are on, and the fans spin, so therefore the PSU must be good.

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 uses 51 to 125 Watts of power.

With a Power Supply that has a weak voltage power rail, you will see LED's light, and fans spin; BUT not enough power to turn the Processor on.

Power Supply also needs to be plugged into motherboard to test, because you need a Load on the Power Supply.

PSU is KNOWN to be good? I mean KNOWN.
Not, "It's brand new so I know it has to be good"
Okay, moving on.

CPU OK?
How did you test it? Install on another working motherboard?

Are the Electrolytic Capacitors on the motherboard good?

http://capacitorlab.com/visible-failures/index.htm

http://www.youtube.com/watch?v=Lut7MX5Dd_A

Capacitors on the motherboard are used as Filters, and Voltage Regulators.
The ones used as Voltage Regulators are in the Motherboard Voltage Regulator Circuit,

http://www.hardwaresecrets.com/article/616

Part of what the Motherboard Voltage Regulator Circuit does, is to regulate voltage for the Processor. (CPU)

The CPU MUST have a steady, 'clean', supply of voltage, and it MUST be kept within the Processor's voltage tolerance range.
Too much, or too little, and the CPU shuts off. BIOS turns it off.

(CPU stands for Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
I know you are aware, just posting for all those who read the solution in the future)

Cpu fan moves & stop No Display


First you disconnect the ATX 4 pin connector (12v, two yellow and two black wire ) from the motherboard and try. If the motherboard is switching on the problem is related to your motherboard cpu core voltage section.

No display but power on ram ok cmos battery ok cpu fan and cpu ok


first check ur display cable for breakr if you have built in display disable it in bios and and if you have addon display card remove them insrert a new addon diplay card if you have display the display section in you motherboard is faulty or diplay add on card is faulty if it still dont work the clock and reset section in your motherboard is fulty to find the at the above section if you have a multimeter check the pci slot A15 means the pci pins facing the processor must have 5v if this is ok your motherboard is ok and the problem is with your display card

Fatal1ty FP-IN9 SLI + Q9400 + BIOS16 = wrong CPU temp + noisy fan


I notice that the solution from myself was posted as a comment. This may prevent some from locating it. I reposted as a solution under a different name. Hopefully it would help those have the similar problem.

In addition to the following solution, you may also set the CPU core voltage to your CPU specification. My Q9400 VCore specification is 0.85~1.3625V. The BIOS auto setting sets it at 1.1625V. I just manually set it to 1.3625. CPUZ shows that C1E and stepping will lower it as necessary. It should provide the CPU more juice when it needs it, while keeps it cool when it is idle.

---------
Ok, this is myself (Recnelis). I may find the solution for this problem. The trick is to use the beta BIOS 18 and increase the "CPU VTT Voltage" in the BIOS "SoftMenu Setup".

The beta BIOS 18 could be found here:

http://forums.hexus.net/abit-care-hexus/149415-bios-updates-intel-e0-stepping.html

To make the long story short, BIOS 16 is relatively stable for Q9400 but could not recognize the CPU correctly. BIOS 18 (beta) can recognize the CPU correctly but is very unstable - random application crashes, blue screen, freeze, etc.

Here is some "history" about the issue. Fatal1ty FP-in9 SLI uses nVidia 650i SLI. If you google "nVidia 650i 45nm quad core", you will find a lot of people has the similar issue. Many websites suggest that it is because of the difference between the release version of the Intel 45nm quad core and the one sent to nVidia for testing (due to that nVidia turned off Intel's request for acquiring its SLI technology according to some rumors). Some forums suggest voltage is among those differences.

In the BIOS, you may notice that the voltage settings in the "SoftMenu Setup" are different from the actual voltages in the "PC Health Status". In my case, the actual voltages are similar but lower than the settings. One exception is the "CPU VTT Voltage". The BIOS automatically set it at 1.2V, while the actual voltage in the "PC Health Status" shows it is only a little above 1.0V. That is more than 16% drop. 1.0V is too low to keep the system stable. Guys in o/c world usualy increase the "CPU VTT Voltage" up to 1.5V to keep the system stable. Since I'm not o/c'ing my system, I do not go that far. For my particular case, when I set it to 1.31V in the "SoftMenu Setup", the actual voltage in the "PC Health Status" is 1.2V, which is what the auto setting trys to do. For your system, you may want to increase the setting one notch at a time to safely increase the actual voltage reading.

Before this tweak, my system cannot even run more than 30 minutes under BIOS 18. After this small tweak (under BIOS 18), my system becomes a whole lot more stable (no crash so far after a few days of using). It passed RealTemp torture test (using Prim95) many many times without a single hiccup. I tried to post this at least one week after the system runs in stable status; but I think some of you may still be searching for the solution.

More good news for those who want to keep the Fatal1ty IN-FP9 SLI/Q9400 for a while: I even installed Windows 7 RC (build 7100) with the new nVidia Windows 7 mobo driver and graphic driver. Everything is running smoothly so far.

Good luck to your tweaking.

Your solution re motherboard


"voltage regulator module" thats have next to core voltage connector it's supply to cpu
cpu need 2 volt 45 amp and our power supply can produce voltage 12 volt 3 amp so motherboard can produce more amp for cpu . 6 mosfet using for this process it's near by cpu
