Question about EliteGroup 915P-A Motherboard

2 Answers

Motherboard fried? I tried to turn on my computer and it would not come on. Initially the green light came on when I tried to turn it on, but it would not boot up. I tried to reset power and now it will do nothing. I opened it up to see what was going on and I cannot find anything obvious. When I pushed the power button the fans will act as if they want to spin, but they won't. I attempted to check the power supply and found that when I disconnect one of the connectors from the motherboard I can get the fans to come on, but the computer still does not appear to come on. The connector looks like it says PWR2 and it is a small 4-pin connector in the middle of the board. Does anyone have any ideas. It is about 2-3 years old. Please help!

    I have the exact same problem. I did notice if i try to power up after removing the 4 pin auxiliary power connector the system will initially try to power up but shuts down completely after about 10 seconds.

    Schmolly,

    In these case like this were a board does not boot it's usually a failure in one of the components or a connector as worked it's self loose.

    First I'd try re-seating all the connectors and and bus cards (graphics cards etc). Then is this fails to solve your problem then I'm certain one of your componets or bus cards have failed.

    Possibilities are...
    1) Processor may have failed.
    2) Processor fan and heat sink has become clogged your processor has slowly cooked.
    3) Your power supply has become faulty and the "power good signal" is no longer seen by the supplies logic controls, preventing it from supplying power to the motherboard.
    4) Capacitor(s) or inductor(s), resistors(s) or diode(s) on your motherboard have failed creating an open or short circuit. This prevents the correct logic level being generated for the PSU power good signal. Hence system will not start.
    5) A fault has developed on one of your bus cards, and this prevent the system from starting.
    6) Dust/Dirt has accumulated in your bus, processor or memory connectors and this prevents the proper electrical connections from being made. Hence, the system will not boot.
    7) Dust/Dirt build up in your power supply has caused it fail.
    8) DVD/CD or hard drive has become faulty and prevent the system from booting.

    Try looking at the capacitors on the motherboard, see this page for advice on spotting bad ones and how to replace them (at your own risk).

    The best thing to do...unplug all your hard drives, system boards and unnecessary connectors just to see if the system will boot.

    You only need to leave the processor, memory, power and front panel connectors (for the power switch only) plugged into the motherboard. If it starts and stays on then the power supply , processor motherboard and most likely the memory are okay.

    That's about as much help as I can give without further feedback.

    Don't forget to rate this solution and comment on it's quality. Thank you.

Get an ATX power supply diagnostic cable. It plugs into the ATX connector on your power supply, turns it on, and has an LED for the Power_Good signal. They cost about $10. They are fairly cheap.

The problem is your power supply, since the power supply have differrent output voltage there is 12volts, 3volts and so on. the 12volts output voltage is not giving enough power. you can determine this by detaching the 20pins from your motherboard coming from the power supply then power-on the power supply then use a jumper wire insulated but scraped both ends (conductor visible) then connect it to the green connector and the grey connector if the fan of the power supply doen't rotate then you 12volts output voltage is busted.

Dell Vostro 220 won't turn on. Checked plug with volt meter and getting power to power supply. Back green light is illuminated. Could it be the mother board?


Usually that happens when there is a power spike and the internal resistance gets fried. It's easily replaceable by anyone with medium to high technical skills but I recommend sending it to be serviced (especially if you're in warranty). This resistance's purpose is to protect the motherboard (it fries so that the motherboard doesn't) so don't worry, it's nothing major.

I would need to know what all you are trying to run in your computer to offer much assistance, but hot plugging power cords in computers is a good way to fry the motherboard. It sounds like you don't have a big enough power supply for everything you are trying to power, so that when you connect enough of the power plugs, the supply shuts down from trying to draw to much current.

If you post your hardware specs, I will try to offer more assistance.

Blingking light on my motherboard, no power.


Chances are your power supply and computer is fine! From other forums on this problem (which I also had), I've learned the following:
1. If you unplug the computer for a half hour or so (the blinking green light will gradually slow down and quit) and plug it back in, the situation will correct itself and the green light will be steady; however if this does not work,
2. a reset that works for a lot of people with the blinking light problem involves leaving the power supply plugged in and unplugging the power supply connection at the motherboard (it usually also has a blinking green LED) and plugging it back in. To read up on how to do this, Google "blinking green light on computer power supply" and read through some of the forums and you'll come on more specific instructions. Usually, you have to wade through everybody telling you to replace the power supply or your motherboard is fried. It's worth a try for a quick fix, just in case those situations don't apply!

Dimension 5100 will not turn on


Could be a bad motherboard? If your power supply was really fried it could have also fried your motherboard.

Fried something?


A half volt will not make any difference. Sounds like the power supply is malfunctioning. Start by trying a different one. Keep in mind that you may have fried the new motherboard by using a faulty power supply. Popping sounds indicate a short or loose/exposed wires, and are never good with any electrical device, especially a laptop since they are sensitive to power fluctuations to begin with.

Either the new power supply you purchased is not functioning correctly. But, assuming it is now that you are getting some form of power to your PC, it is very likely the motherboard. Whatever fried your old power supply (or it could have just been the power supply itself) most likely fried your motherboard in the process. Probably not the CPU since the MB can't even post.
