Computer boots for 1 second then turns off

[shobi4]

Hi All,

I have had this issue for quite sometime..!!!
Got a big query before i move on..!!

Your insights will save my day.!

The following is my RIG.!

Asus Maximus IV Extreme
Intel Core i7-2600K Sandy Bridge 3.4GHz
Vengeance® — 16GB Quad Channel DDR3 Memory Kit
Enthusiast Series™ TX950
ATI Radeon 5770 HD - 1 GB
Seagate 5400 RPM 500 GB (Music)
Seagate 5400 RPM 1TB (GAMES)
Seagate 7200 RPM 2TB (DATA/Program Files/Backup)
INTEL SSD 40 GB (OS)


My PSU went bad, so it was replaced with HX Series HX1050 Power Supply..
After which it was working fine till about 20 days, after which it failed to boot for more than a second.!

I thought it was the board or the ram or the gpu.
But everything turned out to be fine.
So replaced the HX 1050 yet again.

Now I went through the forum, i was able to find that the problems are with the phase change in the psu, so i have asked for replacing the HX 1050 with the older TX 950...


Is there any work around, without me frying the board?

Kindly let me know your thoughts..!!

Hello,

You seem to have a very impressive rig that could potentially generate huge amounts of heat. Try checking if all of your fans are working, check the connection of cpu fan, the cooling paste, etc...

You didn't say when you built this but based on the components I would guess in the last year or so. A third power supply in a year is outrageous especially since you bought good quality power supplies. I would question the purity of your power coming to your house. I would look into a full sine-wave ups for that rig.

A good 450 Watt PSU is capable of powering that configuration.

Try assembling your system outside of the case on a sheet of cardboard (i.e. electrically non-conductive surface) and see if it'll POST. You'll have to hook up a power switch or momentarily short the power switch header on the motherboard's front panel header to start the computer.

Hi Guys thanks..!!!

Yeah this one is a beast..!!!

The problem for me going for a BIGGER smps is the 12v railing (amps)..
i had a 550W to run the GPU, it failed to power the current gpu, so went for more..!
Took it all the way to 950 since i was considering to have crossfire.!

Coming back to the heat.

i have about 4 fans on the RIG, all are running.
I use the HAF X Cabinet from Cooler master.


no cracks on any capacitors thus far.
There is no leak on the processor of the metal paste.

What i did notice is that the HX 1050 is a odd type of SMPS where u have extender cables to power on the hdd's which are detachable.!

so i have currently powered all the hdd's via a single cable..
so i am under the suspicion, that the wattage is not going right way..!
i will dismantle the hdd's and check..
should have a clear understanding by tonight..!!

Will update how it goes.!

A third power supply in a year is outrageous especially since you bought good quality power supplies.

The Rig was built 2011 June.

Still 18 months is too early for PSU's to go bad..!!

the TX 950 got fried when i went to replace, they gave me with the HX 1050.
Then i started having the problem of machine not booting.
Thinking its a problem with the PSU, i gave it back and just received a replacement.!

i love the board.. i am worried of it getting fried..
Thats the reason i posted, to have you experts help me out with the problem @ hand.!!!


The electricity @ my house, i got it checked.
The wattage, and the amps, match.!
The cable's good.!
The earthing's been checked out as well.!!!

Still what it is that i am missing, i dont understand.!

The purity of the power I am referring to is not whether the output is correct on a single time but whether you are getting brownouts and spikes throughout the day. Do you see your lights dim when the laser printer turns on? That is a brownout on that circuit. Similarly when electric heat and air conditioning in your house kicks on that will cause a drop in voltage in the house for a second or two. Multiply that over multiple houses on your grid and those brownouts and spikes when the company sends more power for the brownout can cause damage to sensitive electrical components. I have all my computers, stereo, and television protected by UPS. Not a whole house filter but it help extend the life.

Now I am not saying that it is definitely that, but my power supplies last years. I have an Antec that is 8 years and going. Two other over 4 with no problems. It is possible you got two bad ones but I still think it is spikes and brownouts killing you. You really wouldn't be sure unless you could have someone perform some forensics on the bad power supply or a monitoring of your power over days.

True, the PSU's are supposed to last longer.!!!
I will work on the power side..
Right now, i do believe that the low voltage/voltage fluctuations do happen from time to time..!

I have the Rig, running via a UPS..
Shouldnt that help? or should i go for a stabilizer?

 

[jnkweaver]

That should help as long as it is a good quality ups that reacts quickly.

This is the UPS i use currently.
APC Back-UPS 1100 VA

Can you look into and let me know if that will hold good?
or should i change it?

 

[jnkweaver]

That one should.

Hopefully it was just bad luck and you got 2 bad power supplies.

 

[shobi4]

The UPS states that the max power out is only 660W..
Using a 1050 W PSU over this UPS isnt it cutting short of the actual power?


Edit: I apologize, mistyped the wattage..!

 

[jnkweaver]

It is true if you are drawing 1050W and the power goes out that the UPS may not be able to handle it but I believe that your 1050W is way extreme and you won't be drawing that much power. I think that UPS will do its job of filtering the power.

When ever the comp does this.

If i go ahead and press the button in the image, 3-4 times.
The machine boots up perfectly.!!!!

Its called Q reset button

When the LN2_Mode switch does not work and your CPU cannot resume function, press the Q reset button to temporarily stop the power supply to the CPU and help the CPU recover from a frozen state.!!!

I apologize with the typo earlier..!!!

APC 1100 VA is the UPS i have.

APC PoweChute Personal Edition will tell you what the total power draw from the UPS is.

Download it and install it.

 

[jnkweaver]

It will be less than 300w

APC powerchute doesnt work with that model of mine

It will be less than 300w

But why does the RIG start when i hit the button?
Its confusing..

I tested out yesterday, gave separate power out lines to the harddrives from the PSU.
It kept Running..!
Will try to turn the RIG on, with direct power tonight and let you know..!!!

I would love to see where it gets those numbers. Maxxed out your GPU is 225w. Those calculators assume that everything is running at the same time. Tell me when you would have 4 hard drives 1 ssd, your dvd spinning, your cpu and gpu maxxed? I suppose if you are in the habit of transferring sets of files from hard drive to harddrive while backing up, while gaming and while watching a movie that is possible but I don't see it as likely. Your power supply requirement is closer to 550W you had.

True, i suppose i havent seen it run over 30% CPU utilization at max..!

But any idea's on how the Q Reset switch would play in turning the machine on?

 

[shobi4]

Hi guys,

Communicating with the Asus Support and their tester team.!

Will update when i hear from them!!!..

 

[jnkweaver]

That Q reset is made for overclockers. When their machine freezes up from too high an overclock the push that button so they do not have to reboot.

But i havent overclocked!!!
Why would it fail?
or has the setting been changed?

 

[shobi4]

Hi Guys,

Sorry for a month of absence..!!!

With round about call's to all the support for the M/B and the PSU..

It was found that the PSU was faulty.. Its strange but in my case, its the 3rd Continuous Faulty Device from Corsair..!!!

i went from TX 950 -> HX 1050 -> HX 1050 -> HX 1050 -> TX 850.

Finally, i have asked the support to downgrade to TX 850 since TX 950 is no longer available...!!!

Will update once i assemble every piece of equipment..!!!

Thanks..!!
