I have built my own systems on again off again over the years, so I know enough to be dangerous. I am dealing with a system that turns itself off after two or three seconds. I have run the power supply on its own for 15 mins, under the load of the sata drive, cd rom, sys fans, ect...

I have disconnected the reset switch to eliminate it. I started wondering if it was a temp reading or protection doing it so I unplugged power to the front temp panel. The last thing I did was pulled the motherboard to ensure there was no short behind it. I can find nothing visual.

Any ideas guys or gals?

Will provide any info asked for, I'm not going to leave ya'll hanging. This is driving me batty.

You are not alone with this issue, we have three similar at the moment.

Please give a full list of all your hardware, include the brand and model numbers.

I will get the exact info when I get home this evening. It's a liquid cooled gaming system from ibuypower.com. Never had an issue for 2-3 years. It was called the Guardian. Will add specifics tonight. Thanks for the interest, hopefully we can find a solution for all three.

Thanks for the update.

Troubleshooting on the bench is the best way to go. If at some point you have removed the cooler, did you completely remove all traces of the old TIM, from both the top of the CPU and heatsink plate?

Take anti static measure, check the locking barbs on the cooler pins poking through the back of the MB are properly engaged.  

I put the board on the empty MB box.

Start with the bare min. CPU/cooler, fan plugged into the CPU fan header, no RAM, nothing else at all, 

With the PSU off, > clear the CMOS, > switch on the PSU, > power up. 

If this fails.   Even though you have attempted a PSU test, it could still be faulty.   The only sure way is to have it tested, under load, at a repair shop or, swap in a known working one.   If you still have a fail, then the MB or CPU is the issue.  if a success, the PSU is faulty

[Mikebrathole]

This is the system I am working on. On my next attempt, I will follow the advice you gave iammykyl.

To be clear, I have not removed, loosened, or tampered with the the CPU or cooling system. The simple fact is, this is the first system I've had with liquid cooling so...less is better.

As said, I,ll follow directions above and post results.

So the mounting system will not be as for a stock cooler.

If this is a pre built system? please give the mode/brand.   If a custom build? please give the specs, MB/CPU/PSU/RAM, and the cooler brand/model.

The coolant may have evaporated, or lost through a leak, this would cause almost instant overheating and shutdown.

awaiting your next report. 

[Mikebrathole]

The system would probably lean towards custom, although it started as a pre-built package.

The MB: GA-X58A-UD3R. GIGABYTE
Ram:x3 Corsair 4GB(2X2GB) 1333 MHz
cpu: ?
Processor: ?

The CPU Test worked. As indicated in the picture.

Thanks, that's a good start.   Testing the RAM is going to be a bit time consuming. Please confirm this is your board. > http://www.gigabyte.com/products/product-page.aspx?pid=3449#sp  

Test #1. Only tests if the stick is so bad it won't work, does not test for errors.  

Please ensure to take anti static measures, and switch off the PSU when working on the computer.

 

Tests slot #1.

Use a marker pen and number the sticks 1 to 6.  Mark an envelope, Test one.

Insert stick 1 in slot #1 and power on. , if OK write stick 1 OK on the test sheet.

Remove stick 1 and insert stick 2 in slot #1 and power on, Do the same with all 6 stick marking down the result.

 

Test #2.

New envelope marked Test two.

Insert stick 1 in slot 1 and stick 2 in slot #3, power on and write down result.

 

Test #3. New envelope.

Stick 1 in slot 1, stick 2 in slot 3, insert stick 3 in slot #5. result.

 

Test #4.

Stick 1 in slot 1, stick 2 in slot 3, stick 3 in slot 5, insert stick 4 in slot #2. result.

 

Test #5. 

Remove stick #3 from slot #5 and inert it into slot #4. result. 

 

Test #6.

Insert the last two sticks, (5 and 6) into slots #5 and #6. result. 

 

Can you beg borrow or steal a known working PSU?

 

When testing, take note of the temp LEDS at top, just left of  the RAM slots. 

[Mikebrathole]

Before I proceed, there are only three sticks. They were only used in the white ram slots. Sorry for not including that originally.

[iammykyl]

Not a problem, that makes life easier. 

 

Please ensure to take anti static measures, and switch off the PSU when working on the computer.

 

Tests slot #1.

Use a marker pen and number the sticks 1 to 3.  Mark an envelope, Test one.

Insert stick 1 in slot #1 and power on. , if OK write stick 1 OK on the test sheet.

Remove stick 1 and insert stick 2 in slot #1 and power on, Do the same with stick 3, marking down the result.

 

Test #2.

New envelope marked Test two.

Insert stick 1 in slot 1 and stick 2 in slot #3, power on and write down result.

 

Test #3. New envelope.

Stick 1 in slot 1, stick 2 in slot 3, insert stick 3 in slot #5. result.

How did the tests go? an update would be appreciated. 

[Mikebrathole]

Iammkyl,

Please accept my deepest apology, life literarally kicked me right where it hurts. I'm pretty much just getting to projects again, but let's just say I got put down with two kidney stones and surgery to remove them. No fun for any guy or gal I guess either.

I did the ram tests and all three were good. No, errors, no hiccups.

I did have a suspision at this point however, and connected the motherboard cables and power switch. Instant power off when powered on. IF it powers on at all. It seems it requires unplugging and plugging in the motherboard connector several times to get that 1 second power up. Your the tech, but I'm almost convinced it's the motherboard.

[iammykyl]

Not a problem Mikebrathole  .   Very painful, looks like the Sonic blaster did not work for you, good to here you are back in circulation again.

Just as a troubleshooting step, with the PSU switched off, press and hold the clear CMOS button on the back I/O for 15 seconds.

With all the RAM installed, shorting out the pw/s pins, the rig runs, (no MB short) but when you connect the other front panel plugs, problems. 

 

 

and connected the motherboard cables and power switch

If that included other case cables? remove all, except the pw/s and test.  if OK,

Short out the Reset pins, if OK. Add the plug and test, if OK, than

Connect the Message Power Sleep LED. and test.

If present, connect the System Speaker, be sure to match the +/-

If still running, connect the USB 2.0/3.0/sound, one at a time, then the OD, then the OS drive.

Ok, pictures clarify everything.

#1 everything working fine
#2 We noticed an odd fact this morning, which I am showing in picture #2, the motherboard seems try to take power when the motherboard plug connector is being inserted, but as soon as you seat it, powering up with the switch is a no-go, as seen in # 3.

We did try to clear the CMOS for 15 seconds.

Also, I did get to test with an alternate power supply, same result. I have also tried different power switches, same result.

Sorry, but your reply #14 is not clear to me.

#1 everything working fine

Can't see that the that you have the two main power cables connected.

#2, the motherboard seems try to take power when the motherboard plug connector is being inserted, 

Did you have the PSU switched on when connecting the 24 volt and 12 volt Plugs?   The PSU must be switched off at all times when connecting/disconnecting any plugs to the MB.   Please explain a bit more.

**************

To clarify.

A.   PSU off, then, 24v and 12v cables plugged into the MB, then switching on the PSU, then shorting out the pw/s pins on the MB front panel header with a small screwdriver, the PSU and CPU fans spin up and keep going?

B.   PSU off, connecting the pw/s plug to the header on the MB, (pic #3) switching on the PSU and pressing the power on button on the case, no fans spin? no movement at all?

C.   Please inspect all the front panel wires, can you see any bared bits?   See pic.
