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

also... my computer dont detect the GPU, if i check the divice manager, it only shows the board's integrated graphic card
so... the GPU is working... the MOTHERBOARD is new... so what's going on
please someone help me
