Hi all,

I need help on this one. PC has not been turn on for about a week. No issue before, tried to turn it on yesterday and not powering on anymore.

What I have done so far

  1. Swap each of my RAMs on different slots to test - no luck

  2. Reseat CPU and reapply thermal paste - no luck

  3. Unplug graphic card and tried to power it on - no luck

  4. Tried to power it on without any HDD or peripherals - no luck

  5. Jump power switch without using the front button - no luck.

Here is the video: https://imgur.com/a/SeYyIfZ

I’m not sure what to do now.

Edit:

I have also tried with different PSU. That was the first thing I did, bought new one 😅

Edit 2:

The only reason why I have not change the mobo is because I was hoping is not the mobo. So I don’t have to look for used LGA1150 Intel board.

This pc is mainly for my partner to use for photo editing, as all the softwares needed is in this pc.

    Test with a different PSU and see what happens.

      Why exactly do you say the OP is trolling? Seems like a pretty legitimate request for help to me.

        Issues with most of those things he's allegedly tried wouldn't stop a computer from booting through to the CMOS, while the obvious stuff hasn't been tried (eg PSU and mobo). I mean, reseating the CPU, really? Don't do that.

        • askbargain on 21/02/2023 - 13:35

          obvious stuff mobo? what should he do? rotate it?

    Three more things to try. After these you are out of options available to a consumer.

    1. Clear CMOS.
    2. If the board has dual BIOS, try switching to the backup BIOS.
    3. Swap PSU as suggested by websterp.

      I will try to clear CMOS, probably might change battery too. But then, the mobo still has green light. So I assumed the battery still okay.

      • alvian on 21/02/2023 - 13:40
        +1

        The green LED is powered by the PSU, not the CMOS battery.

        • froddoog on 21/02/2023 - 13:44

          Okay, so might be good to change the battery?

            @froddoog: A weak battery can corrupt the settings stored in CMOS, and corrupted settings can prevent a PC from booting. Disconnect power cord. Take the coin battery out (the PC will work without one), short the CMOS reset pins to set it to default, reconnect power cord, and try starting the PC again.

            @froddoog: even with a weak cmos battery, you should still be getting a post.

            Although not entirely impossible, in over 300 PC's, i have never had a PC not boot at all due to a CMOS battery, but it doesn't hurt to test/change

              @TilacVIP: Can confirm have had computers with a dead cmos for years, only thing that happens is when AC power is cut the bios resets settings.

  • skid on 21/02/2023 - 13:39

    Doubt you'd have any, but check for shorts i.e. bare wire touching your case. Otherwise, yeh, try swapping the PSU.

  • John Kimble on 21/02/2023 - 13:44

    Jeez, sounds like a car engine revving to me 😂

  • Pelicannn on 21/02/2023 - 13:46

    With the new PSU did you use the new PSU cables? PSU cables are not always compatible. I.e you can’t always just swap the actual PSU in and out unless it was a brand new identical PSU.

    • froddoog on 21/02/2023 - 13:47

      Yes, I use the new cable and I unplug all the old cables :)

      • Pelicannn on 21/02/2023 - 13:50
        +1

        PSU plugged directly into the wall? Try another wall socket.

        Otherwise I’d be leaning towards corrupt CMOS somehow. New battery?

        • iDroid on 21/02/2023 - 13:57

          Wall socket ain't the issue here.

          Dead CMOS battery also wouldn't cause this.

          A corrupt CMOS possibly - there's likely CMOS reset pins on the MB - worth a shot.

          • Ramrunner on 22/02/2023 - 17:19

            @iDroid: Just wanted to say wrong on the dead CMOS battery not able to cause this.

            LITERALLY today fixed the exact same issue repalcing with a new CMOS battery, and have done so multiple times since I started working as a technician in 1997.

            It can indeed cause this. Now, I will admit it's unlikely on a modern board (most of the fixes I've done are on boards almost a decade or more old), but never say never.

        • froddoog on 21/02/2023 - 13:57

          Yes tried that as well.

          I have not try new battery. how do we fix corrupt CMOS?

          • Pelicannn on 21/02/2023 - 14:03

            @froddoog: New battery will clear it. Just leave the old one out for a few minutes and push the power button a few times to drain any capacitor charge.

    LGA1150, decade old. Hackentosh?

    Reading above look like board has failed if clearing CMOS doesn't work

    • froddoog on 21/02/2023 - 14:02

      Yea probably worth building my partner another PC.
      But then we are not sure how to transfer all the configurations that we have, such as softwares that we have bought and probably have to re-path all the photos we have edited.

      • Bid Sniper on 21/02/2023 - 14:07

        If HD is working, the data is salvageable.

        So build new PC, install software, then can perhaps copy over program folder and appdata/roaming folder. Depends on software. However considering how old this system is probably best to start new anyway.

        • froddoog on 21/02/2023 - 14:50

          Yea, I think that would be the best way.

          We do already have another one mainly just for gaming.
          Will look into that :)

          Thank you!

      • AustriaBargain on 21/02/2023 - 14:22

        If you didn't have a backup of the data already then make one now. Get a SATA to USB adapter or whatever if you need to, this PC is so old that the drive surely uses SATA.

        • froddoog on 21/02/2023 - 14:54

          I think most data still intake, I plug in all my HDD and SSD on the new pc, most are still there.

          Just that we will need to re-path everything again onto the software that we had on the old pc that died

          Just hoping not to build another pc this soon after we have just built one 2 months ago :(

        Windows has actually gotten good enough now that you can swap you HDD/SSD into a whole different PC and it'll usually boot and run without any issues.

        I once stuck an old SSD into a Macbook I was about to reformat. Without me doing anything, the damn thing booted into the old Windows 10 install that I was trying to wipe!!

        • froddoog on 21/02/2023 - 14:51

          Oh okay! sounds good, maybe we just build another new pc

          We might try that, maybe there is hope :D

      • 7ekn00 on 21/02/2023 - 16:59

        To transfer OS / software to new PC, use "Disk Genius" and select the "Migrate OS" option - works wonders!

        How:
        Build new PC, plug old HDD in as main boot drive, let windows reconfigure and login and install Disk Genius (on the old HDD)
        Shut PC down, insert the new SSD/HDD, but boot from the old one still
        Fire up Disk Genius, select "Migrate system" (and select the new HDD/SSD and also tell it to reconfigure the BIOS for new drive)
        Once migrated, shutdown new PC, remove the old HDD and it will boot from the new one

  • Marty156 on 21/02/2023 - 14:09

    Check all the volts from psu, while in situ and turned on. If there is a short cct somewhere on one of the rails, psu will shut down.

    • froddoog on 21/02/2023 - 14:56

      Yea, looks like it. Will try and google how to do all those things. thank you

  • Typical16-bitEnjoyer on 21/02/2023 - 14:10

    Missing key information - what CPU and Mobo model?

  • AustriaBargain on 21/02/2023 - 14:20

    Hold old is the PC that has not been turn on? Maybe it is time for a new one that will be turn on.

    • froddoog on 21/02/2023 - 14:56

      We usually turn this pc on when we need to use it for photo editing or video editing.
      But mostly we have been using the new one we just built 2 months ago.

      • AustriaBargain on 21/02/2023 - 15:58

        Maybe buy her a MacBook if video and photo editing is the major concern. I bet even the base M1 MacBook Air/Pro will be more powerful than a 10 year old gaming PC. For storage space a USB C portable SSD should probably have you covered if 256GB base storage isn't enough.

  • garetz on 21/02/2023 - 14:51

    Looks like you got a short somewhere.

  • 7ekn00 on 21/02/2023 - 16:54

    Specs?

    Older motherboards have capacitors that can dry out and the mobo dies :/

    Also check the pump of the AIO water cooler, sometime when the pump dies, the motherboard detects zero RPM from the "fan" plugged into the CPU_fan header and refuses to boot ..

    • froddoog on 21/02/2023 - 22:30

      I dont even remember what the specs of this pc was.

      gtx 980
      asus sabertooh z97 mark 1
      Intel i7-4790k (maybe)

      I might try to check the pump, or change it to the normal fan one.

      • Typical16-bitEnjoyer on 22/02/2023 - 19:07

        Sorry but your system is old as hell. Just part it out all out and sell, buy something new. No point wasting time.

        • harshbdmmaster718 on 22/02/2023 - 19:46

          Hey don't say that I have the same processor and even crappier specs for the rest! And there is a carpet of dust coating everything inside I just had a look the other day lol. At least I think the dust will keep things dry and prevent rust.

          I don't play games so I don't need anything better really. I think it's plenty fast. 😀 (I did set minimum processor speed to 100% in power settings though)

        • froddoog on 23/02/2023 - 11:04

          Yea maybe it’s time to part with it.

          We did just built new pc, that’s why we haven’t use the old one for quite sometimes. Unless we need to use it

    Honestly I opened up my PC recently just to have a look inside (it was dust city) and I swear after I closed it up it's a lot quieter than before, so I think I might have accidentally unplugged the CPU fan power cable or something.

    So I am kind of worried that it will overheat and stop working too. I guess I will find out eventually 😂.

    Just an idea OP maybe you did the same thing.

  • randomusername2017 on 21/02/2023 - 17:13

    Is that laying on carpet with the side off?¿

    Try running with the board out of the case to eliminate any shorts from standoffs/backplate.

    • froddoog on 21/02/2023 - 22:27

      I did one as well on the table, but no luck

    A lot of serious advanced comments here but I think people need to understand how dumb some of us consumers are (I am one of them).

    Up until recently all I wanted was a Windows 11 compatible PC (while my current PC still works lol).
    I was so upset I missed this deal https://www.ozbargain.com.au/node/736203 it was the cheapest Win11 PC I had ever seen.
    Then I used Windows 11 once recently it was so terrible I can't explain it lol you can't find anything it's literally un user friendly. Now all I want is a PC that can ONLY run Windows 10 so I can't possibly accidentally upgrade to Windows 11.
    Turned out I had what I wanted all along. 😂

    Take it to MSY. They might charge a small service fee but they can work it out for you.

      I might do that if all else fails.

      • TilacVIP on 22/02/2023 - 08:21

        Just be aware, they'll need to troubleshoot each component combo [PSU/RAM/Motherboard/CPU] out of the case.

        Be prepared for at least a $150+ bill.

        I had a similar issue as yours where PC was power cycling. Mine was a PSU issue.

        Try ripping it all apart and rebuilding it outside of the case.

  • ShannonN on 22/02/2023 - 01:38

    when you say it wont turn on is power getting to the cpu, as in is the cpu fan spinning. I'd check if the power on button may be screwed

  • Sito85 on 22/02/2023 - 09:29
    +3

    Unplug everything, including ram and CPU. Only connect the mobo to the psu and try to start it. If the fans start and stop like what you showed on your video, then it's a faulty mobo. If it starts and the fans keep spinning, then turn it off and start adding components one by one until it faults.

    • A-mak on 22/02/2023 - 15:25

      +1.

      next step, reseating the cpu + ram, try to get into bios before putting on HSF + thermal paste. (heat will slowly climb so if the fan spins and you see the bios menu just hold the power button).

      Any noticeable thermal paste anywhere outside of on top of the cpu die?

  • Loopholio on 22/02/2023 - 18:17

    I have an old PC here that likes to do the same boot loop. I narrowed it down to a faulty video card. It should have been a simple job of removing the card and using the CPU's built in GPU, but it wasn't that easy for me. I forget exactly what I had to do but here's what I can remember.

    Remove the video card
    Turn the PSU power off using its switch on the back then press and hold the power button for a few seconds to drain all power
    Reset the BIOS using the jumper method
    Now here's where my memory gets a bit flaky
    Find a cheap video card. Ideally one that doesn't require external power. Plug it into the second slot, not the main fast slot
    Turn the PSU on and press the power button

    I know my old PC wouldn't boot if it couldn't find a video card. It should have booted, but for whatever reason it wouldn't.

    If your hard drive / SSD is okay you can slap it into another PC and Windows will boot after finding new drives. I've done this myself a few times and it just works. If windows complains about not being activated you can get a new key by using this method.

    • froddoog on 23/02/2023 - 18:12

      I did try to do most of the troubleshooting that was suggested here.

      The mobo has built in GPU, do you think that should work too?
      If not I might try to ask some mates whether they have card that doesnt requires power.

      I think if the mobo has failed, we will just built another pc if we have no choice.

      Thank you for the reddit post! Will definetely look into tha :D

      • harshbdmmaster718 on 23/02/2023 - 18:29

        I think if the mobo has failed,

        By the way I remember a forum post asking "what in your PC failed" and surprisingly motherboard was up there towards the top. So it sounds likely.

        • froddoog on 23/02/2023 - 18:46

          :( was hoping that will be the last thing that failed.
          But looks like I can just plug in to any new built and still have all my software installed (hopefully)

          • harshbdmmaster718 on 23/02/2023 - 20:25

            @froddoog:

            :( was hoping that will be the last thing that failed.

            Yeah I know I was shocked too. It's like the main part of a PC should be made to last the longest.

            But looks like I can just plug in to any new built and still have all my software installed (hopefully)

            Yeah pretty sure that's how it works. As long as you have your SSD/HDD with your OS on it you can plug it into any hardware and it will all be there.

      • Loopholio on 23/02/2023 - 19:03

        Yes the built-in GPU (part of some CPUs) should work unless it has been disabled. I had a lot of trouble getting mine to work. I don't know exactly why, but when I used an actual monitor (not my TV) the GPU was happy to put out a signal. That took me a while to work out.

        Resetting the BIOS should automatically change the built-in GPU to Auto. Make sure you have a monitor plugged in before powering on the PC. If you can, use an actual monitor, not a TV (for maximum compatibility).

  • Bargain4Days on 23/02/2023 - 12:13

    Dumb question, is your aio water cooler pump plugged back in? Or is it dead, as once the water inside the AIO overheats the cpu shuts itself off.

    • froddoog on 23/02/2023 - 18:12

      I took out the entire aio, but it is still power cycling.
