    Unhappy Will not post after a shut down

    I have a 4 year old Dell Inspiron 530 tower. Yesterday I shut it down. When I later pushed the power button the light blinked and nothing else happened. If I held down the power button it would light for a moment then go off and just keep repeating this. I think took the cover off and pressed the power again. The CPU and back panel fans would start then quit then start then quit for as long as I held the power button down.

    First guess, either the powersupply or the motherboard is going bad.

    While checking connections I had the power cord unplugged. I plugged it back in and the computer booted normally! Now if I just do a restart, the computer boots normally. I ran the Dell hardware diagnostic tool and it found nothing wrong. But if I shut it down and wait for a minute, it will not reboot. At least not until I unplug it for 5 minutes. Then it boots just fine.

    I unplugged everything external except monitor, keyboard and mouse. No joy. I remove all the RAM and reinserted them one at a time. It would reboot the first time after the plug was put back but fail to reboot after shutting down w/o removing the plug.

    Any suggestions as to the cause? Motherboard, powersupply or ???

    I'll spend a little time and $$ trying to fix it, but when a new equivalent box can be had for $700 or so, I'm not sure how much bother is worth it.

    Thanks

    Does this wiki article shed any light on your problem?

    Sounds like it could be overcharged capacitors, if it's consistent and leaving it unplugged fixes it.


    Try removing the power entirely, then holding the power button down for a minute or so. This should COMPLETELY drain everything off, and hopefully it'll continue working fine afterwards.

    Long term, you will probably need to replace the power supply.

    If the above suggestions don't work, you might try stripping it down "bare bones" and start working with it from there.
    (Start with just the CPU, PSU, GPU, Monitor, and a single stick of RAM. Remove everything else, then try to post).
    Take note of and examine the CPU~heatsink fitting, also examine the capacitors for bulging or leaking;
    especially those located around the CPU area.

    If it's an older computer check the CMOS battery, replace if suspicious or more than 3 or 4 years old.
    You might also consider resetting the BIOS switch on the motherboard. You'll have to dig up a MB manual for precise directions.

    It looks like it could be your PSU. Give us more details on your specific hardware.

    Thanks to all who answered. It really does sound like it is a PSU problem. I'll open it up and take a look for bad capacitors. Then I'll replace the PSU anyway. That's a lot cheaper than replacing the whole box. As to what the box is, it is a Dell Inspiron 530.

    I'm guessing that your PSU is in the 300W range, and that is typical of many OEM brands.
    A 400 to 500W replacement model should suffice, unless you plan on making some radical hardware upgrades, like dual GPU cards.
