i change the powersupply, i have one cx750w, and the screen is black, when i put the old graphic card everything works fine.
i check in pc-specs.com and it says the mother board is not compatible, the tecnician in the store says i just have to update the bios. ill probably just buy a new mother board compatible with my processor
