I just swapped my PSU and GPU with RMA ones, swapped out all power cables with new ones and reconnected everything.

Tested PSU by itself. It works.

It was working prior to me taking out the parts for RMA, but one of those hardware were causing shut-downs.

Now when I push the button power after putting in the new parts and connecting everything, it'll start up then stays shut off with the 2 phase LEDs lit up. A green and a yellow.

Any suggestions to what the problem is?

Does it stay on when you boot up into Safe Mode ?

I can't get to POST, it just shuts down immediately.

Can you get into the BIOS to see if your graphics is set to AHCI ?

I press the power button, fan spins and everything lights up, turns off right away, I wish I was able to.

Then it won't turn on anymore unless I turn off the PSU and turn it back on.

See what you get when you boot with the GPU card removed.

Okay, I will try, I am going to unplug everything except the power cord from the back.

My PSU for sure is good because it has a self-test button that I used multiple times, my GPU was just RMA'd but still, worth a trying...

I tried it, still same problem, one stick of ram, still same problem.

I was hoping that with the GPU removed that the VGA would have kicked in so I think that could rule out the GPU.

If it had been a memory problem then nothing would have worked - neither the fans or the lights.

With all memory removed do you get any indication of a memory error code when you boot.

Some computers have bleep error coded while others use their lights.

Can you Google to see if your machine uses its lights as its error codes - that may explain what the yellow light signifies.

Can you check inside of the case that all earth points are secure.

I'm not sure if a SeaTools for DOS disk would boot up to determine the state of your HDD, but I think that is something you should try if you have access to a machine to create the disk.

http://www.seagate.com/gb/en/support/downloads/seatools/

Use the links for SeaTools for DOS as the one for Windows is the installable version.

You haven't said which version of Windows you are using, so changing the boot order could prove difficult.

I hear no bleeps, the mobo speakers may not be working.

PHASE LED that signifies the voltage for certain things.

Earth points, as in the screws on the mobo to case? because I have never tamper with it and it was working before the RMAs.

Windows 10 Pro.

Were you able to create a SeaTools for DOS disk to check the hard drive ?

As you aren't able to get to POST it may be worth checking the voltage of the CMOS battery, or just change it.

How old is the machine ?

I built it in 2010, I did remove the battery, waited 10 mins and put it back, should I get a new one? I also hit the CMOS CLR button in the back of my PC.

No I did not DOS Disk check, but they were fine before I swap the parts out.

PSU can be considered new (also self-tested AX1200i) and GPU was just RMA'd.

I'd get a new battery unless you have a multimeter that you can check the voltage of the one you have.

CMOS batteries are reckoned to last 5-6 years, although the one in this laptop that I bought in 2011 isn't doing so badly.

I don't recall much information on the battery itself except made in japan, anyway to know for sure what batter I need

Yes, take it out and have a look at it - it will have a number on one side.

They are usually CR2032.

I am just going to put this out there, but the CMOS battery shouldn't be able to stop the pc from getting to POST.

UPDATE:

I decided to trouble by baring my pc to only MB and CPU, which worked then slowly add parts and cable turning it on and off, it turned out to be a power cable that was shutting it down right away.

Now I put everything back and it actually starts up to the splash screen but then it turns off again, any suggestions?

A CMOS battery can stop some computers from booting.

I was dealing with a no boot on another forum and a couple of other members chipped in that theirs were able to start after changing the CMOS battery - but I accept that won't always be the case and wasn't in that instance, I also accept that it should be eliminated as a cause.

At what point in fitting the bits back did it return to the boot problem ?

I have no idea, I have to do it again, I was just happy it wasn't instantly turning off the moment I hit the power button and actually loaded some, I didn't realize it would shut off at splash screen, first off, going to get a new battery.

At least you will eliminate that as a cause even if it doesn't resolve.

I've known DVD drives cause similar problems, but can't remember if it was the actual drive or its drivers, but when you do another bare bones then make a note of what works and what doesn't.

How long do you think I should let it run for each test, 1 minute? I hope this doesn't damage something else turning it on and off @.@;;

Continued power shutdowns can cause data corruption, but how many bits do you have to refit and I think you will know from previous experience how the computer will perform as you add each bit back and for how long before you add the next bit.

Disconnected my PC from peripherals, moved PC to another spot in my room and plug in power-cord only. /Shuts-down by itself after turning it on and waiting a few seconds.
I took out the old CR2032 Battery and put in a new one. 3V.
I disconnected everything, I left CPU fan, 1 more fan, 3 sticks of RAM CPU power, Motherboard power connected. /It is not shutting down by itself, force shut-down.
I self-tested my PSU, Green light and positive working.
Plugged in SATA for my SSD and its power cable (Shared power cable with my HDD and front E-SATA port) /It is not shutting down by itself, force shut-down.
Plugged in SATA for my HDD, front E-SATA port and my second SSD as well as its power cable /It is not shutting down by itself, force shut-down.
Plugged in SATA for my DVD drive and its power cable. /It is not shutting down by itself, force shut-down.
Moved my heatsink fan to another slot on the MoBo (Where it originally was prior to the RMAs) and swap the cable for my HDD/SDD areas from a direct line to PSU to one that takes power from the MoBo (CPU_FAN). /It is not shutting down by itself, force shut-down.
Plugged in my GPU, screwed it in, mounted my GPU fan. connected power cables. /It is not shutting down by itself, force shut-down.
Plugged in my wireless card, screwed it in. /It is not shutting down by itself, force shut-down.
Plugged in my audio card, screwed it in. /It is not shutting down by itself, force shut-down.
Plugged in CORSAIR link digital in to Motherboard and power supply. /Shuts-down by itself after turning it on and waiting a few seconds. Did more testing, unplugging it from the PSU will still make it shut down by itself, unplugging it from the MoBo and keeping it connected to the PSU allows it. /It is not shutting down by itself, force shut-down.
Looking in to it further, it was my mistake to plug the CORSAIR link digital in to the F_1394 thinking it was a internal USB port.
All parts has been tested.
Connected all peripherals in regular spot.
Success, PC preparing automatic repairs :(.
For some reason hitting the CMOS CLR button and removing the battery multiple times also replacing it did not reset my BIOS to default, still retained same password, hooray? Double checked BIOS settings.

WINDOWS BOOTED AND I SEE MY SAME OLD COMPUTER, GOD BLESS.

Problems: Bad power cable forcing it to turn off when turned on and CORSAIR LINK digital in the wrong slot on the Motherboard.

Big thank you to Boggin for staying with me.

Note: I been letting it run for at least a minute before force shut-downs.
