[Solved] A Serious Problem I Cannot Fix with My Newly Built PC

Hi guys,

I just finished building my PC, although I can turn it on, install windows10, when I tried to install the GPU driver or do something that requires more heat dissipation, the screen will be blackout showing "No HDMI signal" while the PC is still running.

When tried to restart it, the screen will only show "Asrock" and a white dot circle under it. But the circle will stop spinning after one or two seconds and the screen becomes black again, showing "No HDMI signal".

When the screen shows the "Asrock", I can still push F11 for select boot driver and re-install windows, which will repeat the blackout curse after successfully installed. Or I can push DEL button for BIOS. During Windows installation and in BIOS, the screen won't be blackout.

I have to admit it is struggling and my hands are tied.

I will be much appreciated if anyone could kindly help me out of this, or recommend a specialist who would visit my place (Brunswick, VIC) to sort it out for a reasonable price.

Details of my PC:
Intel i5 8600k
Corsair H100i Cpu Cooler
Samsung 960 EVO 250GB
Asrock Z370 K6 Mobo
Corsair LPX 3200MHz 2*8GB
Corsair Case 400C
Corsair RM650x
MSI 1080 8G Gaming X

Thanks for your patience!

_______________________________UPDATE___________________________________________

After I removed the GPU, and plugged the hdmi into the motherboard socket, everything so far is smooth.

Now here comes the problem, is the GPU a faulty one? I got it half month ago, should I return it?

Thanks

________________________SOLVED____________________________

Use another caple, which is DP cable, instead of HDMI

Problem solved, immediately

Thank you guys

    I had similar experience when I had monitor plugged into motherboard socket instead of graphics card one.

    • mrhorse on 06/01/2018 - 15:31

      lol，I am sure I plugged it into GPU. But Thanks

    • mrhorse on 06/01/2018 - 16:48

      After I removed the GPU and plug the hdmi into motherboard socket, the resolution can reach 2k and more impontantly, it's not blacking out!

      Now, what should I do with the GPU? It's a $700+ brand new MSI 1080 GPU bought half month ago. Does it mean it's a faulty GPU? Should I return it?

    Does it load Windows Sucessfully? You can normally tell from HDD activity light if it's starting to load windows.

    Try and take out the graphics card and try just with the onboard video. Akajin could be right though.

      I would start here also

    • sitdowndisco on 06/01/2018 - 13:58

      Yep, definitely try onboard video only. You need to start isolating parts and the gpu is the logical place to start.

      • mrhorse on 06/01/2018 - 15:32

        Thanks, I will give it a try!

  • b2dz on 06/01/2018 - 13:26

    Also does your card take external power? Check it's in properly, and then try another cable from the PSU on it's own rail if possible.

    • mrhorse on 06/01/2018 - 15:32

      Thank you for your advice!

  • Yummy on 06/01/2018 - 13:29

    Have you try other HDMI cable yet?

    • mrhorse on 06/01/2018 - 15:33

      It should be a good one. As it shows the bios face steady and long-lasting. But thanks!

    Have you tried turning it off and on again?

    • mrhorse on 06/01/2018 - 15:34

      Lol! Definitely! Old school trick

  • jzdhgkd on 06/01/2018 - 14:38

    For further isolation testing you could try with only one ram stick and then the other.

    Also you mention "something that would require more heat dissipation" - have you tried installing a temp monitor of some sort? If there's a specific part heating up that could tell you more

    Or maybe you forgot to peel off the plastic film before mounting your water block

    • mrhorse on 06/01/2018 - 15:37

      I just re-positioned the rams from 13 to 24. Now installing windows again to test.

      I used an monitor software, the temperature is fine, 40 degrees while installing the gpu driver.

    have you disabled onboard graphics from bios?
    sounds like windows is jumping signal to onboard vga

    • mrhorse on 06/01/2018 - 15:38

      That sounds like something new! Can I disable it in BIOS?

      • b2dz on 06/01/2018 - 16:52

        Yes you can usually. Just be careful though as if the other card isn't workig, you may need to reset the BIOS if you disable video.

  • MacGarnicle on 06/01/2018 - 15:42

    Along with what others have said including checking your 12V power cables are properly seated, plugging your HDMI cable into your motherboard slot then attempting to boot using onboard graphics and so on;

    Are you able to boot into safe mode to rule out any windows driver shenanigans? If you don't get the boot option screen try using your windows disk/recovery USB to change your windows boot settings and boot into safe mode.

    Also go into your bios and see if you have a pc temp monitoring section, most mobos will have them. Report your CPU idle operating temp here to rule out a bad CPU cooler install.

    • mrhorse on 06/01/2018 - 15:50

      Thanks
      In bios, it shows cpu temp is around 40 and mobo temp is 34.

    so everything works fine when you connect the monitor into your motherboard? so not using your GPU at all

    • mrhorse on 06/01/2018 - 15:52

      I am trying it now, please bear with me a moment

    • mrhorse on 06/01/2018 - 16:09

      I removed gpu and plug hdmi cable into mobo, tried to install windows but the ssd cannot be detected?

      • [Deactivated] on 06/01/2018 - 16:10

        What drive are you installing windows on?

        • mrhorse on 06/01/2018 - 16:28

          I just re-plugged thr ssd into the slot. Now it’s working. The windows is installed and I am going to install some driver to see whether it will be blackout or not.

    • mrhorse on 06/01/2018 - 16:42

      omg.. it seems working.

      Without GPU, the resolution can reach 2k and at least, it's not blacking out!

      Now, what should I do with the GPU? It's a $700+ brand new MSI 1080 GPU bought half month ago. Does it mean it's a faulty GPU? Should I return it?

      • b2dz on 06/01/2018 - 17:43

        No mate. Not yet at least.

        Run a windows update if you haven't already. Get all later windows patches etc before you install the card.

        Remove any other device on the same rail. CD drive etc. Remove any other drives other than windows for now. Try it again.

        • mrhorse on 06/01/2018 - 17:53

          Thanks, I will give it a try.

        • b2dz on 06/01/2018 - 18:03

          @mrhorse:

          *Other than the drive with windows installed.

          As few things as possible plugged in.

          You can run a memory test as well. I used memtest previously but things may have changed these days. Can even try and run things with one stick of memory to isolate the issue.

  • alexlim2000 on 06/01/2018 - 17:02

    Isnt the 650W power supply too small? The 1080 must eat a lot of power.

    • mrhorse on 06/01/2018 - 17:07
      +2

      Thanks for your reply.

      I did some research before buying the PSU: normally 600W is enough for 1080, so I reckon it is not an issue of power supply.

      • Cartman2530 on 06/01/2018 - 18:48

        psu should be fine for a 1080, i use a corsair 600w psu with mine and its overclocked with no problems.

        do you have another pc to test the 1080 in?

    • nomoneynoproblems on 06/01/2018 - 19:12

      650 is plenty for a single gpu.

    • iforgotmysocks on 06/01/2018 - 19:19

      I have a 1080 running fine on 550W

    "It's a $700+ brand new MSI 1080" why ppl so rich and ask ozbargain for help

      They're just kids. I bought a Radeon 9700 Pro for $890 when it came out. We all do stupid shit.

        back then, only can afford Radeon 9550 flashed to 9600xt

    The Black screen error is common when installing a new gpu. Sometimes Windows mistakenly tries to send your data to a non-existant extended screen. Keep the hdmi in the mobo plug and install Geforce Experience, then update it. Now shutdown and plug hdmi into gpu again. If this does not work, crash your pc into troubleshooting mode and turn off Fast Boot. Hope this helps.

    • GaryQ on 07/01/2018 - 19:06

      Ha! My old man is in his 80s and insists and having every possible device connected to his PC. I made the mistake of showing him how to hook up the 40" TV behind him to the PC so he can watch his downloaded Inspector Morse on the TV instead of the 19" LCD

      Now at least once a week I have to remind him over the phone that the HDMI has probably taken over as Default Speakers / Display, and the Browser is on the screen that is turned off behind him
