Brand & Model of Mobo-CPU-RAM-Graphics-PSU. Old & new.
Cannot get my rig to start
I do not know what else I can do. I built my first computer about 3 years ago and came home one day to find it shut off. When I tried to power it up, the CPU and case fans would start to turn and within 5 seconds everything would power down. I send the PSU back (still under warranty) for a new one with no change in results. Since then I have replaced my graphics card, RAM, sound card and was still experiencing the same immediate shut down. With nothing working, I finally broke down and bought a new processor, motherboard, and coordinating RAM. Last night, I put everything together and excitedly turned on the power switch only to experience the same exact immediate shut down. I cleared the CMOS and tried again. Nothing. I do not know what else to do. The case and the CPU fan are the only things I have not replaced. Is it possible one of these is my problem? Any help would be greatly appreciated as I am completely out of thoughts or ideas and ready to buy a prebuilt system!!!
Thanks,
Nick

I would suggest testing on the bench.
1) Remove EVERYTHING from the case
2) Set the motherboard on a non conductive surface. The motherboard box is perfect for this. DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can actually conduct electricity!
3) Install the CPU and heat sink.
4) Install 1 stick of RAM.
5) Install the video card and attach the power supply connection(s) to the card if your card needs it.
6) Connect the monitor to the video card.
7) Connect the power supply to the motherboard with both the 24pin main ATX Power connection and the separate 4 or 8 pin power connection.
8) Connect power to the power supply.
9) Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
10) Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. Then touch both pins with a screwdriver to complete the circuit and boot the system.
If all is well, it should power up and you should get a display. Then assemble the parts into the case and try again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.
If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.

I appreciate your time, I tried this with the old board without hooking to the monitor, and it would not work. Could my new board be bad as well?
Possible but not likely. Did you do the bench test, exactly as I posted, using the new hardware?
I did, I had previously read an old post by Linderman, so as soon as the new board would not boot, that was the first thing I tried. The fan on the CPU starts to spin, the LED on the mobo lights up and about five seconds later everthing stops, but the mobo light stays lit.
