my motherboard is a gigabyte GA-Z77-HD3 and my video card is an xfx radeon hd 7850. This is my first build so im still new to this but i put everything together and when i turned on the computer for the first time no image showed up on the monitor. after looking for a solution all i could find is that my video card is fried (but the fan still turns on) or its my PSU (xfx pro 650w) i also tried using 3 other video cards and using a few of the same 6 pin plugs from my PSU. i am able to boot the computer and use it when there is no video card so im thinking it has something to do with the motherboard. thanks for any help.
