I am a first time builder. I had an old tower and I decided to buy all the components and install myself.
I put it all together and turned it on, the led on the motherboard flashed once and the fan on the cpu, psu, and video card gave about half a spin, then the system shut off. No sound on the system speakers.
Took it all apart, went with the breadboarding advice. Hooked up only the psu and the cpu with its fan, plugged in the 24 pin power cord and the 4 pin cpu power. Turned it on with the same result.
Took off and reinstalled the cpu, took the RAM in and out. Nothing, not even a beep. I was very careful during construction. The only thing I can think of (other than just plain faulty components) is that I was not grounded at all times during assembly.
PSU: OCZ Modxstream-pro 500W power supply
CPU: Intel i5 with stock fan
Motherboard: MSI P55-CD53
I need some advice. At least how can I narrow down which component doesnt work

So now the system does nothing when you press the power button?
Try using the power button on the motherboard to rule out a problem with the case or front panel connectors.
You've probably already done this if you've breadboarded the system. If nothing at all happens, either the motherboard isn't functioning at all or the power supply is shot. If your processor or RAM was no good, the motherboard should at least turn on and give you a beep code.
If you have another modern power supply, you could try booting the system with it. If you have some means of testing the power supply (the guts to your old computer perhaps) then do so.
I suspect the motherboard, though. If all else fails RMA it.

Try hooking the power supply up to just a fan...not attached to the MB. If it still does the same thing, it's your PS. If not, it's your MB.
You could also try only one stick of ram to see if any of the sticks are bad.
Look on the motherboard for any blown capacitors. Toms had trouble with that model MB during overclocking, but I'm guessing its a power supply problem. OCZ has a very good customer support program.

I have tried with many configurations, still the motherboard bleeps on and quickly shuts off. I cannot power up the ps without it connected to a motherboard, and I only have a laptop so no luck with trying the ps on another computer.
I don't see anything physically broken on the motherboard, and I have unplugged and reinstalled every component. Plugged all power cords in correctly. I think its time to send it back.

Don't send "it" back till you know which part is broken.
Here is a guide on how to jump start your ps using a paper clip.

Wow thanks that was easy. So I am assuming that if the psu turns on its not the current problem with the build.
So its either the motherboard or the processor - I'm going to guess motherboard on this one. I was very careful not to touch or bend any of the pins on the processor, so I really don't think its my new i5. Also, the fan seems to want to work, it gets a couple spins in before the computer shuts down.
Now I am about ready to box the MSI board up and send it back - the only question is whether to replace it or get a different one altogether.

So a quick recap:
I tried to plug everything in when the components were all in the tower to no avail.
I took everything out of the tower, put it on a insulated surface, plugged in just the MB, PSU, and CPU. Still just turns on and immediately shuts off.
Tried the RAM in the correct position(s), both with a single stick and multiple sticks. Also tried with and without the video card. Also tried to have a number of components in breadboard configuration. Still nothing.
Used a paper clip in the PSU and found that it powered up, plugged in an optical drive and it worked.
So that leaves motherboard and processor. Processor is right out of the box, as in the MB. I am going to return the MB. Any last thoughts?

Unfortunately, the problem could still be your PSU.
A cut 'n paste from a previous thread:
Try to verify (as well as you can) that the PSU works. If you have a multimeter, you can do a rough checkout of a PSU using the "paper clip trick". You plug the bare PSU into the wall. Insert a paper clip into the green wire pin and one of the black wire pins beside it. That's how the case power switch works. It applies a ground to the green wire. Turn on the PSU and the fan should spin up. If it doesn't, the PSU is dead.
If you have a multimeter, you can check all the outputs. Yellow wires should be 12 volts, red 5 volts, orange 3.3 volts, blue wire -12 volts, purple wire is the 5 volt standby.
The gray wire is really important. It sends a control signal called something like "PowerOK" from the PSU to the motherboard. It should go from 0 volts to about 5 volts within a half second of pressing the case power switch. If you do not have this signal, your computer will not boot. The tolerances should be +/- 5%. If not, the PSU is bad.
Unfortunately (yes, there's a "gotcha"), passing all the above does not mean that the PSU is good. It's not being tested under any kind of load. But if the fan doesn't turn on, the PSU is dead.
If you have breadboarded the system with motherboard, CPU & HSF, PSU, and a case speaker and you get silence instead of a series of long beeps (no memory), then your PSU, motherboard, or CPU is bad. At that point the only way to determine what is bad is by substituting known good parts.

Ok lets see...
All standoffs are properly in place, check and double checked, also took the mobo off the tray and still no success.
RAM is DDR3 which is what the board uses (as do all i5/i7 boards I think) running at 1600, which is fine by the board's specs.
G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRH - Retail
Dual Channel Intel Core i5 & Core i7 CPU for P55 motherboard
Brand spankin new.
Tried resetting the CMOS, both with the jumper on the pins off and in the two configurations available including the one spec'd for reset in the board manual. Also removed the battery for like 10 minutes. No good.
No beeps whatsoever in any setup. LED for phase 1 power flashes on for a fraction of a second before dying
Tried the paperclip trick with the PSU. Fan spins, plugged in an optical drive and it openned when I pressed the button, so definitely getting power. Maybe I will borrow a multimeter from a lab and check it more, but I'm pretty sure PSU is ok. Definitely going to try the grey wire if I can find a multimeter. Oh, and the I/O switch on the back of the PSU was on for anyone who thinks this might be the problem
So what are the chances this is a processor problem. It's a new i5 out of the box. Right now I'm am pretty sure its the MOBO
