New rig everything connected fine, no boot

Hello, I just put together a new rig. Bought all parts from newegg, connected everything appropriately several times and i have followed your step by step guide. I find myself with no way of knowing whats wrong with the rig. I'm thinking its the psu or the mobo. Maybe you guys can help me clarify. Everything seems to turns on fine, all fans work (gpu, cpu). The mobo has three led lights next to the cpu fan to show speed and power phases. It shows only two lights lit up (indicating its running in phase 2). I've tried swapping out psu's, video cards, and i've tried booting up with just one ram stick and still nothing shows up on the screen. I've tried resetting the CMOS using the jumper pins and by taking out the battery. I've tried booting with just the bare essentials also. Any help would be greatly appreciated. Heatsink is on the cpu chip with thermal paste,



X-Power Pro 650W PSU
Intel Quad Core 2.6ghz
MSI p43-c51 Mainboard LGA775 socket
EVGA GeForce 9400GT 1GB
6GB (3x2GB) ADATA DDR3 1600 FSB
Western Digital 250GB 7200RPM HDD

you plug in the 4 pin connector into the mobo ?


The 4 pin connector is secure, there are 3 of them on the power supply actually. Tried all three and none make a difference.


And here are pictures of my power connection, I tried to take clear pictures as best i could.

There is 4 pin connector for graphics cards, and there is a connector for your CPU. There is only 1 connector for the CPU and you said you had 3, thats why I think your tying to plug the GPU cable where the CPU cable should go.

Can you show us a better pic of the cpu power. It should be a single 4 pin connector.
It looks to me like you have the PCI-E video card power plugged into the cpu.



Alright well the PSU box it came in has a description of the plugs, it brings 2 PCI-E plugs (one is a 6pin plug, and the second is a 6 +2pin plug). On the box it states that it brings one ATX12V connector "4pin" and one ATX12V connector 8 (4+4) pin, these are the "3" four pin connectors that i am trying to explain, i tried to take a picture of the single one connected to the cpu and the other two that seem to be almost connected to each other right beside the sinlge one thats plugged in. hope these Pictures help, i also included a picture of the PSU Box with the descriptions.

Yes sir, tried all three and still a no go. :( 

I'd also like to add that the front panel connectors are all connected appropriately, but there are three LED ligts on the motherboard, the manual states that depending on how many are lit determines what phase the cpu fan is running at or something. Mine only shows two lights lit up, so might that mean that the power supply isnt powering it up enough to have all the lights on or display anything on the screen? Thought the power supply would have been more than enough to power this. Here's a description of what i'm talking about.

I have an update that may help solve the problem, i switched out motherboards to a AsRock 775i6G and DDR ram and everything works, computer boots up properly. Could it be that the processor i have doesnt fit into the MSI p-43-c51? When i go to DXDIAG it tells me that the processor is a "Intel(R) Pentium(R) 4 CPU 2.80ghz (2 CPUs), ~2.8ghz". The MSI motherboard i bought says it supports Pentium Dual-Core processors and it has a LGA775 socket. Is it possible that i bought the wrong motherboard for the processor? any help will be greatly appreciated. Thank you.

The mobo supports

Model
Brand MSI
Model P43-C51
Supported CPU
CPU Socket Type LGA 775
CPU Type Core 2 Quad / Core 2 Extreme / Core 2 Duo

If this is your CPU

Intel® Pentium® 4 Processor 2.80 GHz, 512K Cache, 533 MHz FSB

http://ark.intel.com/Product.aspx?id=27447


Then no that CPU will not fit the Socket 775 that CPU is a Socket 478




That CPU you linked is a single core though, dxdiag says Intel Pentium 4 CPU 2.80ghz, but it has (2 CPUs) there also. Wouldnt that entitle it being a dual core or something?

He said he has a Core 2 Quad at 2.6ghz. Not a socket 478 Pentium 4. LOL



Scratch the whole core 2 Quad cpu thing lol.

Thats the problem i dont have the oriinal box the cpu came with and i dont have any idea how to find out the exact model number of it. All i can do is show you the Screenshot of DXDIAG telling me what the cpu is. Unless you have another method of how i can find out what cpu it is?
