Question about EliteGroup NFORCE 570 SLIT-A Motherboard

The system fails to boot up after a new power supply was added

Well I just added a new, much more powerful power supply to my system. The problem I'm having is that the system now will not boot up. It turns on for about 1 second before then shutting right back down. I tested every connection individually and found that the cord that connects from the rightmost side of my power supply (A blue 8 pin to the right of the main 24 pin motherboard power supply) is what is causing the system to fail. Upon trying to boot it up with this unplugged, it works, but I get no display, and seeing as the 4 pin connection it runs to is just to the left of the GPUs (I have dual with SLI), I'm assuming this is the connection that powers them.

System Specs:
3 GHz dual core pentium processor
3 gigs of DD2 RAM
dual GeForce 8600 GT graphic cards connected with SLI card
Five cooling fans, two LED.
The new power supply is a 950W, the old was 600W. This new one uses the detachable wire bundles whereas the old had all the wires connected inside the system.

    It's a Coolmax 950W Sli ready PSU. We also tried an ultra 750W power supply and had the same issue, though didn't go into the details of the pulling out wires because I wasn't around so my Dad just figured it was defective and replaced it with the old one.

  • c_drouillard Nov 12, 2008

    It says here that it's Model NO: CUG SERIES.

  • c_drouillard Nov 12, 2008

    Oh and for extra information, before I got the new PSU and the reason I did was because before, with the old one in, the computer would randomly just shut down while I was doing things, generally when I was running multiple programs at one time, and someone recommended I get a new PSU because the old one may be dying. The old one still works right now, it just has that crashing issue every now and then.

  • c_drouillard Nov 12, 2008

    The motherboard is an NFORCE 570 ****-A

  • c_drouillard Nov 12, 2008

    umm...570 Sl1T-A, apparently it's censored.

  • c_drouillard Nov 12, 2008

    Yes my set up matches that, the issue at hand is the fact that when the CPU power, the 12v P4 connector plug, is causing it to fail to start up. When this is unplugged, the system activates and stays powered, however, it does not boot.

  • c_drouillard Nov 12, 2008

    ECS NFORCE 570 SL1T-A is what's in the white. It also says FSB 1066 on it too.

  • c_drouillard Nov 12, 2008

    Okay that's what I was figuring it was. So I figure the temporary solution would be use the old PSU, but really I'll need to replace the motherboard, won't I?

    Last clarification request - do you know the motherboard name/model?  It's usually stamped on the board in reasonably large white text.

  • Quinten van der Werf

    It sounds like the 12v rail may be getting overloaded.  Can you post the model/brand of the new PSU so I can give you more accurate info on the wiring suggestions?

There should also be a brand - the nVidia just relates to the chipset that the board uses, but its OK, lets check the wiring first.  If we still have trouble I'll get you to double check for the brand name.
Lets just check that you have the following plugs in place:

  1. The 24 pin plug from the PSU (blue) to your motherboard - this powers the board itself.
  2. A 4 pin 12v P4 connector plugs into the motherboard (near the CPU).  This is the CPU power.  It runs from the 8pin blue socket on the PSU.  Make sure that the end plugging into the motherboard is only 4 pin.
  3. No power cables required to run the 8600GT so the red sockets on the PSU are empty.
  4. Power cables going to all your peripherals (hard drives and CDroms).  These run from the black sockets on the PSU.
Does your current setup match that?

    OK, great you have the setup correct. The motherboard is expecting a signal OK reponse from the PSU before it will start.  This sounds like it is not happening for one of two reasons:

    1. The PSU is (co-incidently) faulty and not outputting this signal.  I have had far stranger coincidences occur.  You can check this by booting another system with the PSU or testing it with a PSU tester (approx $30 from a gadgest store, eg Tandy).

    2. The motherboard is flakey - most likely this is the case.  This would also explain the initial crashing you have with the older PSU.  The old PSU may have a slightly different power output coming through the motherboard connectors so that the board identifies the OK signal correctly.  The newer PSU would most likely not be allowing this signal to go to the board as it has detected a fault.  Rule out the new PSU to start off with, but I am sure that this is where the problem is coming from.

    3. Other things to check which can sometimes help: reseating the memory and the CPU.  Most likely won't help, but most tech guys are happier if you have tried this.  Don't remove and replace the CPU unless you have some new thermal paste handy to put under the heat sink (after you have cleaned the old thermal paste out of course), remembering that you only need a rice grain sized drop of thermal paste on the CPU.

    Whoops, did not see the EliteGroup section in the title.  Yes, ECS is the brand.  Thanks.  Not that it really matters too much at this stage unfortunately.

  • Quinten van der Werf
    Quinten van der Werf Nov 12, 2008

    Unfortunately yes, if it is the board, that is what will require replacing.  This can sometimes be a good thing as you can get something that will support a better upgrade path and more features.

My computer has been shutting of be itself lately now it will not boot up at all, can you help?

Hi, maybe a number of many things unfortunately. Have you installed new into your computer? (RAM, Graphics Card ,etc...).
If so take it out and restart the computer and see if it will boot up. If this is the case then you probably need a more powerful Power Supply Unit. If nothing has been added then a possibility that the Power Supply Unit is now failing, computer is overheating - check vents are not covered up with dust, objects etc.., the thermol paste between the Processor Chip and Heat Sink may have dried out and lost the contact between them, Motherboard could of failed.
Like I said before it could be a number of things but these are the most common.

After power on Fans are running but no Videosignal, no bios startup.

Could be 3 things Memory or CPU or Powersupply. are you getting any beeps if so how many, how long. try taking all the memory out and powering up see if it beeps if so try to put one stick of memory in at a time and see if it will boot. if you get no beeps with memory out check powersupply some PS's have a red switch on back for current input. switch back and fourth about 20 times uning a pen and set it to the right current for you location. put ram back in see if it will boot if not its trial and error of the PS and the CPU replacement and it still could be the RAM giving false readings. yea i know sounds like a ball of fun.

Dont't boot anymore since my power supply died

When the power supply failed, it took the motherboard out at the same time. Time to replace it.

SX 1810 NX compaq presario 3200+ sempron processor,,,, the power light LED is on when i disconnect and connect the power cord but when i turn on the PC the system gets tripped.... what is the problem ,how...

If you are getting solid or flashing lights but nothing else then you most likely have a bad power supply or defective motherboard. I would take this time to inspect the motherboard (mobo for short). It should not have any capacitors (they look like tiny soda cans) that are bulging at the top, swollen at the top or leaking any kind of fluid. They should be perfectly flat. If your motherboard looks good then I would get a new power supply. You will want to take out your old power supply and look for the output watts. It will probably be in the range of 150 to 300. You must buy a power supply that has more than what you take out, never less. If you have put in a bigger video card or have a lot of cards that you have added to the system you will want to increase the power supply over 400 watts. This has been my fix for this problem. Let me know what you find out. Also if you get the computer to boot even once take that opportunity to get your files off immediately. A bad power supply can sometimes cause other parts to fail. Also a bad power supply does not always mean no power. Sometimes it can mean not enough power to power up the system. You could also try removing other components such as memory, cables to drives, etc. to see if that changes your boot up progress.

2500 dell inspiron fails to boot when new fan comes on

You are drawing too much current from the power supply with the current hungry fan.Try using a different fan that draws less power on start up. Or use a limiter to lower the input voltage draw on start up. These are usually found in fan speed controls You could also use a voltage dropping adaptor like the one use to quite fans down . They drop the 12 volt voltage to 7 volts by connecting the two voltages usually found on the power connector 12v and 5v and and adding them together getting a 7 volt output. You can also try connecting the fan directly to the power supply and avoid using the motherboard connector.The problem with this is you will not get use of the speed controling sensors used in the motherboard connections. Hope this helps you with your problem.

Computer keeps re-booting while installing any operating system

Were the two power supplies you tried inclusive of the original failed drive or not. In other words did you try a total a 3 power supplies including the one that failed?

If not, please do so. That is, immediately analyze the original known part failure, the power supply or its connection to the board(s) you have tried.

Congratulations for such an exhaustive process of elimination.

At power up about 50% of the time I get a flashing P/.

Sounds like the power supply is failing. The power supplies have protection circuitry in them so that when there is excess current draw, the output voltage is 'clamped' (reduced to a lower level) so that the power supply won't burn up. If you are consistently experiencing this, that's a sign. If you added another drive, a new video card or upgraded the processor a little while ago, the power supply might not quite be up to the task. Even with nothing new added, a lot of power supplies don't like to be operated at much over 60@ of their 'rated' capacity, and their ratings are significantly lowered at any little temperature rise.
