Hi

Newbie to this game.

My First build which I am doing for my dad before I move out so just a bare bones system for internet, email. Pieced together with my left over parts and Second hand bits.

Motherboard Intel945GCM5-F V2
core 2 Duo E4500 CPU
Power supply is 420w & working. Just removed it from my PC ~1 month ago and it was using the same connections.
2GB DDR2 667 Corsair .Model: CM72DD2048r-667/S ECC Buffered.

The Motherboard & CPU were shipped as one. In an anti static bag. I have been grounded while touching and they are from a reputable trader.


Have assembled the whole system including PCI-e card, HDD, DVD and turned on hoping for a happy day scenario. .
That didn't Work.

I have power. The CPU fan whirred and the DVD drive made sounds. Working monitor received no signal.

so I cleared CMOS with jumper ( powered down, switched & left for 2 mins, reinstated and rebooted )
No Dice

Removed PCIe HDD DVD
No dice

Removed Ram
No Dice

I'm stuck. Any help would be greatly appreciated.


PS not receiving error beeps as I dont know where to plug in my mini 4 pin motherboard speaker.
Attached a diagram of my motherboard and where I attempted to plug in mini speaker that came with case

Your speaker connection is very likely going to be on JFP2. Not sure where on there, I haven't looked at a manual for that board. But that will be the correct location.
Take out everything that is unnecessary to POST. Take the motherboard alone, and put it on a cardboard box, connect power, and the monitor. Take out all the ram, except for one stick. Then try to boot. If all goes well, you should have a working system, and you simply add in parts until it breaks.

If it does not boot that way, try the other stick of ram.

If neither stick works, then try something from a "donor" that is known good to test against.

If that does not work, try to swap the CPU into a donor motherboard if possible. At this stage, you would be down to a motherboard or CPU. The attempt here is to narrow down the faulty device.

Of course, all of this is assuming the PSU, is in fact, working correctly.

Thanks for your help.
Do you mean take out the CPU also when I place it on a cardboard box? What is the advantage of doing this as oppose to leaving it in the case?
Also how will I turn the pc on? Wont I need the power switch from the case?

Thanks again.

Also have now added speaker and not getting any beeps. . .

This is not too good a way to build  aPC, especially for someone else.  This maybe anything, from just changing slots (RAM) to a damadged memory chip. Or maybe your RAM is not meant for this CPU?  Here's  detailed specifications of your motherboard.

Nope, sorry, you do actually need that to test. I put it that way because there are a few cases out there with a removable motherboard try. I want to ensure we have not shorts, and want to exclude the tray.

JKD: Welcome to PC World forums. New builds are the source of many problems and usually the hardest to track down. During a power on sequence, if the power supply fan keeps turning, turn it off, stop the fan from turning and listen to the hard drive when you turn it on. Aside from the motor spinning up, you should hear two individual sounds, one where the drive initializes and again when it moves to the ready track. A missing first sound means the drives not booting but could be holding the MOBO from starting. On board video BIOS should be first and then the CPU. A plug in card can be substituted to test this. Are there jumpers on the board for the video?? With on board video, nothing else is needed except the video and minimal memory. New builds are know to have misplaced stand offs so testing outside the case can reveal that fault. Heavyhanded insertion of memory sticks can damage a MOBO and repair impossible at home.

So I have tried breadboarding. (note I only have 1 RAM stick to test with) With the following combinations:

CPU & RAM slot1
CPU & RAM slot2

RAM slot 1 no cpu
RAM slot 2 no CPU

No CPU, no RAM

Each time I haven't had any beeps.

I know the PSU isn't the problem as I have tried using the PSU I'm using on the pc I'm using now and still getting the same.

What is my next play? Source another RAM stick to test? Mobo? CPU?

That is pretty much it. Find donor parts to test against. Ram should cause a beep code. The CPU technically should too. But I would say start with the CPU or motherboard.
