Well for the past month i have been trying to build my computer for some reason something always goes wrong first the power wouldnt work and now that i fixed that the video isnt working i bought a new PSU still didnt work then a new mobo and still nothing are those the 2 only things that can make the video not display?
Of which brand??? Also try the Bare Bones method... Take out the Mobo from the Case..and leave it with only CPU 1xRAM 1xHDD 1xVideo Card(if u dnt have a Onboard) Use flat face screw driver to short pins and start the computer....
What's the specs of this system your having trouble with, including the brand and model of the power supply.
