Hi Guys

basically got the pc from tech fast few days ago.. but doesn't seem to output a signal.

ive got a i3 9100f which doesn't have integrate graphics.

basically - unplugging the cpu gives light to my mouse showing its connected and having power delivery… moment the gpu is plugged in - nothing happens.

ive been trying to use it via HDMI but no luck and don't have any other spare inputs laying around…

ive tried I think nearly everything from cables, turning it on and off again, removing dust, checking other cables and what not…

this does have the generic PSU so it may be that but im unsure…

any help with a keen eye would be greatly appreciated

    I’m gonna suggest something from left field, so bare with me, but maybe try contacting Techfast….

    • Bisah1342 on 18/10/2019 - 20:48

      planning on but just wanted to see if anyone on here had any ideas :)

  • ChillBro on 18/10/2019 - 20:46

    Why's the GPU power cable disconnected?

    • Bisah1342 on 18/10/2019 - 20:48

      was testing it out in that instance with it connected and not…..

      seems like when it is connected the mouse lights up and has input,… but moment the rx580 gpu is plugged in there's no light from my mouse (no power delivery im assuming).

      • ChillBro on 18/10/2019 - 20:52

        Are you able to unplug and reseat the GPU/CPU/RAM or does it void the warranty somehow?

        • Bisah1342 on 18/10/2019 - 20:54

          already unplugged and plugged everything back in…. seems odd..

  • Skramit on 18/10/2019 - 20:51

    Sure it’s not your monitor?

    • Bisah1342 on 18/10/2019 - 20:53

      pretty sure……

      used it previously for other PC and PS4 so doubt it.

      plus the RGB mouse lighting up when its only the cpu versus gpu plugged in is an interesting note…

      • Skramit on 18/10/2019 - 21:01

        Is the GPU seated in the slot properly?

        • Bisah1342 on 18/10/2019 - 21:02

          yes! double checked too but I will try once more

          • Skramit on 18/10/2019 - 21:02

            @Bisah1342: Check the ram slots too.

            • Bisah1342 on 18/10/2019 - 21:06

              @Skramit: will do!

              starting to think its the PSU…. the case fans seem to be intermittently turning on and off.

              it is the generic 500w PSU but I have a rx570 gpu so maybe it is too much power draw?

  • Bisah1342 on 18/10/2019 - 21:15

    going to submit an email to tech fast…. seems like something is definitely dead because now the case fans seem to be turning on and off intermittently… cheers :)

  • EightImmortals on 19/10/2019 - 09:22

    Can you borrow a GPU from some to try it out? (Or just buy a cheapy locally? Never hurts to have cheap parts on hand for testing things.)

    • Bisah1342 on 19/10/2019 - 12:11

      just did that - see below :)

  • myusername on 19/10/2019 - 11:57

    when you reseated the vid card you didnt crack the pci lane?

    • Bisah1342 on 19/10/2019 - 12:10

      no! had another friend of mine who brought some parts and it definitely seems something must have been hit on shipping.. we used extra parts and what not.

      it was shipped via Star Track who are notorious for throwing things (this is the first "fragile" thing ive ordered in a while) in my suburb (to achieve their quick delivery times or whatever), so it could have been that but again unsure.

      definitely nothing broken - I did purchase the generic 500w allied PSU so it could be that.

      all fans are running - lights seem to turn on so im thinking it was something damaged in shipping / PSU issues.

      planning on building my own PC I guess if this was the case…

  • westzod on 21/10/2019 - 14:17

    Keen to hear on any update on this OP. I've just ordered from them and wanting to know how they handle their support etc. just in case.

    • Bisah1342 on 22/10/2019 - 20:36

      was very good - confirmed to be DOA and they emailed me promptly and very transparently.

      10/10 so far will update once shipped and refunded.

      • westzod on 22/10/2019 - 20:55

        Ah nice.. so you're returning?

        • Bisah1342 on 22/10/2019 - 21:46

          yes! bought my own parts as I needed it urgently.
