I tried Parveens solution for this problem on 2 absolutely dead D845GVSR mother boards and it fixed the problem for me on both. On mine you had to permanantly short pins 92 & 93 of the LPC47M172 IC near the ddr ram slots.

There must be a reason for why the motherboard went dead in the first place because from the factory, pins 92 & 93 of this IC are not meant to be shorted. Albeit the motherboards work perfectly the shorting of pins on this IC get over the problem but the original fault is still really there but has been bypassed! Still having said that, what a result!

You should find a motherboard diagram on the internet in case you dont have the manual from it..
the position  of voltage regulators can differ from board to board

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)

Core voltage problems in 845gvsr

Hi,

check the +12V supply(between yellow wire and black wire) at the 4 pin power plug connector for the CPU.
If there is no voltage then you will have to change the power supply(SMPS). Thanks

2. check CMOS cell on motherboard,(3 volt)

3. Bfore power supply changing check on mother board any capasitor is like as damaged or not.
OR check main chipset ic is marked as intel.whenpower on it is very hitting or

Intel D845EPI Motherboard

I have been asked to clarify my problem, so I'll do that as brief as I can.

The Motherboard CPU Fan starts when the Power Switch pins are shorted together with a screwdriver.

Green lights appear on the Motherboard, but there is NO Screen on the Monitor, No Bios Screen, No Nothing !!!

It stays this way until the Power is removed from the Motherboard.

I hope that this clarifies my problem with this Motherboard for Colliewob. Any suggestions ???

Fuse Locations

dear blankslate,
the green light glowing shows that your motherboard is getting power. check your SMPS first. it can be done
by shorting a green and any black wire(not advisable if you are not a technician). if the fan on SMPS fan rotates
then the problem is with your motherboard(Display problem). otherwise it is a SMPS problem(means power good signal
voltage problem).
thanks,

System will not power up

Have you replaced the cmos battery(disc shaed flat 3V CR2032), although there could be more sinister problems than this as the mobo or processor may be damaged.
