    Home now. Left my pc unplugged while I was at work. Held the power button down for 5-10 seconds while it was unplugged. Tried different power cables. My old one, the one I bought Friday and another from my monitor. Nothing.

    Tried booting it up on my surge protector nothing. Directly into the wall nothing.

    The PSU I got was expensive. 620w antec. And its only running a single gtx 970 so idk how it would stop working like that..

    Pretty much ready to just put this thing in the trash

    I built this at the start of 2013 and ive only replaced the gpu since. I5 3570k antec 620w 80 plus bronze. Gtx 970.. msi z77a mobo.. idk

    Hi. Last night I put my computer in sleep mode. Wake up today and I cant get it to turn on. Ive switched on and off the PSU. Tried plugging the power cord into different sockets with no luck. The green light i can see on the motherboard is not lighting up anymore. Help please! Everything was working fine yesterday.
    would not trust the op honeslty... he posting this here !! his computer can post in mmorpg.com but unable to open ?? something off !!

    It's probably the power supply - probably.

    Anything can break. Even expensive power supplies. They are just less likely to break than the cheap ones, and less likely to blow up the rest of your computer should they break. Nothing is 100% reliable (except death and taxes).

    I've also seen bad motherboards and bad RAM keep a computer from turning on. I don't know how bad RAM does it, but I've definitely seen it happen before. I've also seen loose stuff (usually a screw) in the computer short something out, and cause the power supply to trip almost immediately on startup (usually here, the lights will come on and the fan will just barely start to spin, then it all goes black again)

    There is a "jump start" you can do to test to see if your power supply turns on without being plugged into anything else - that would at least tell you if the PSU is capable of turning on (and possibly a short or bad component tripping it out), or if the PSU is just outright dead. I usually jump start mine with a paperclip, if you don't feel comfortable doing it yourself then don't do it, and just take it into a repair shop.

    I have my pc opened up right now. Hitting power doesnt even move a single fan. The mobo lights dont turn on. Its just completely dead. No movement or lights from anything. No sounds or beeps.

    I guess it is the psu..?

    What is a solid psu youd recommend me order?

    Hope they arent hard to reinstall. Ive only ever done ram. Hdd and gpus.

    On a side note if you don't want to bother with all that, on your way home from work, stop by any electronics store and grab another power supply and test it with that one instead.  If it doesn't work just return it.  Most places let you return power supplies in 15 days.   If it works, hey you have a working computer,  if not, its just a few extra minutes of your time returning something.

    I know some covered many basics (if not knowing it works from taking it in for testing as you did) but:

    1. Remove ALL peripherals. This means all USB devices. Only leave the power cord plugged into a known good source.

    There are several steps to follow to narrow down the fault if hardware is suspected but you had yours tested and it fired up so something attached to the pc (peripheral) is likely the cause. This is often a USB device you stick in without thinking. It is critical to remove all devices, bleed power with power cord removed and button pressed over 10 seconds and try to power up with ONLY the power cord attached watching the inside for sound, lights and movement.

    This includes optional drives not required for boot. The power bleed is required in order to clear the CMOS of any existing errors from your previous boot profile attempt that may include a different hardware setup due to even a single addition of a peripheral.

    If the techs were intelligent enough to check that your cooling system wasn't compromised when they tested it then overheating should be an issue. You can still test by letting the pc cool for 10 minutes and try the minimal boot option. Overheating is not common on idle on (especially Intel chips) is using a heat sink even with a compromised fan. A serious issue however on failed water cooling systems.

    In 17 years of IT support I have seen one power issue caused by a failed cord ... one. Unless you kink your cord in commonly strange ways, they are the rarest point of failure and easily tested by swapping with the monitor (it's more common on the monitor if you turn it often).

    Thanks. Just tried this. I have nothing hooked up to it. Even took out my storage hdd. Bled power for 15 seconds plugged in power and nothing. No light no beep no fan movement.

    I have a case fan a coolermaster cpu fan and my psu fan.

    Get a Seasonic, sized between 550 to 700W. Any model of that brand, in that size range, will be decent. You don't need Gold/Platinum ratings, but it won't hurt if you want to pay for it.

    There are other brands/models that will work, but it's hit or miss. Seasonic is the only brand name I feel comfortable saying that pretty much any model in that size range will work well.

    Of course it does, but if you've removed everything off of the power but the motherboard, you shouldn't be having any issues, you have adequate wattage without any video cards, etc hooked up.

    I would definitely start with the simplest thing first and replace the power supply with something comparable (and cheaper) that you can return if it doesn't work.  If you're confident you'll be able to replace the power supply, definitely do that.  If it turns out that it isn't the issue, then you may want to look into that "new computer" idea you were thinking about before as your next step logically would be the motherboard.

    Ya these things can be incredibly frustrating. I lost count of how many times (with both on site and tech desk support) where I tested a pc and it worked fine and when the client tried it later it didn't. 

    However, it is usually important to try the basics again but with even more redundancy. Use your monitor power cable and repeat the steps on a different power outlet, on a different breaker, in a different area of the house. No power bar for test. Hopefully this emulates taking it to the techs to see why it worked there and not at home. Keep it removed from power to for 10 minutes to cool it as if you transported it.

    I suggest taking one additional step and removing all memory modules too from the mobo. Push down tabs at end of slots and they pop out. Note which order and slots they are in for paring purposes. Do this after the bleed and then you power test you hopfully hear a memory beep error. This shows signs that the PSU does indeed have some life and memory and mobo is the issue. No sounds/lights and PSU is still a candidate. Align the notch on sticks when placing back later after yet an additional power bleed, and push down with a little effort until tabs snap closed.

    At least getting it to fire up once then later seeing it fail again likely reveals it's a failing hardware device.

    Do i remove my gpu and ssd? Or just ram

    Cant remove 1 ram. The huge coolermaster cpu fan is sitting over it.

    You should be getting the CPU fan spinning with everything but the motherboard power unhooked.  

    Just so that we're on the same page too, you've made sure that the switch on the back of the powersupply is flipped "on" right?   Simple things like that can be overlooked when you're finding larger issues.

    Switch on the back is on. I havent removed any hardware from the pc besides the hdd atm.

    No fan or anything moves when i power on.

    The fans dont even move at all.

    If your GPU has a power connector to it, remove that as well.  GPUs generally take a lot of power. (though at this point it may be futile as even if you're overloading a powersupply it would generally try to turn on). 

    I really think the PSU is the first place you'd want to start.  Especially if you've tested the exterior, the plugs, etc as you say you have and they work on everything but the PC,  and if you have a basic power cable (not one with a voltage converter or anything like that) then its pointing to a hardware issue.

    Ok all. So no luck on finding a replacement PSU. I did catch that video Octagon linked and picked up a CR2032 battery. Changed my old one.

    Now I have the PC on its side with just the ssd and ram plugged in and its turning on but shutting off and restarting after a couple of seconds. Dont have it hooked up to a monitor so not sure if its showing an error message. Nothing is beeping at me and the fans and lights are running while its on.

    Is this normal? I dont want to leave it doing that if its a hardware failure or something.
