Solved Graphic Card No Signal After Flashy Power Outage

  • 0

Hello, i have a problem

the other day we had a flashy blackout, after that my graphic card stopped giving signal to my monitor…

i had a ASROCK N68C GS FX MOTHERBOARD…
and i have a GEFORCE GTX 650 GPU,

i tried an old GPU and didnt work too… so i tried using my old MOTHERBOARD and both GPU worked…

so i bought a new MOTHERBOARD and it still not giving any signal from any of both GPU…

my new MOTHERBOARD is a ASROCK N68 GS4 FX

the energy cable is connected to the GPU, and i’ve installed the drivers already…

i got the mention that i didnt re-install my OS because it worked properly due the same brand of MOTHERBOARD….

i tested my HDMI and VGA cable from my monitor in another computer and its working…
i tested the VGA cable in MOTHERBOARD’S connection and its working

so… the GPU is working… the MOTHERBOARD is new… so what’s going on

please someone help me

      To restate:
      New MB works with integrated graphics.
      Power supply works on another machine, even with the same graphics card.
      PC does not work with old or new motherboard with the combination of power supply and existing graphics card.
      You did not reinstall Windows.

      Try:
      Flash BIOS with latest.
      Reset BIOS to defaults, then manually set BIOS to best for primary hardware.
      Make sure that you install all drivers for new motherboard, do it with onboard graphics and if necessary, do it in Safe Mode.
      Try reseating graphics card a couple of times in case tarnish in socket.
      Make sure PCIe power connector is attached, if more than one is available, try both one at a time.
      Make sure that if there are more than one PCIe 16x connector, use the first one (top one) or see manual.
      Make sure that all case posts are under correct spots on motherboard, all have screws, there are non under motherboard where there is no mounting hole, and there are no mounting holes without post under it.
      In BIOS primary graphics is set to PCIe 16x slot or ‘PCIe 16x if present’ depending on options for your BIOS.

      If any assumptions are incorrect, please let us know.
      Post back all results. Remember, try one change and test so you know what works and don’t have to back track and try a couple again in different combinations.

      You have to be a little bit crazy to keep you from going insane.
