Monitors won't turn on when I boot computer.

I recently upgraded to a MSI Z97 Gaming 3 and an Intel i7 4790k. I kept the same GFX card, which is a Diamond Multimedia Radeon HD 7850. The problem I am having is that when the card is plugged into the motherboard, and receiving the 6-pin power from the PSU, my monitors won't turn on -- They are connected straight to the integrated graphics on the motherboard-- However, when the GFX card is receiving no power from the PSU, it boots up like normal. But, the downside is, I can't play any games.

Yea, because you need to connect the monitor to the graphics card, not the motherboard. The on-board video is disabled when a graphics card is plugged in and powered.

I initial guess would be that this is your solution right here.

I tried what JobCreator suggested, and it does the same thing as before -- black screen-- does this mean that I should go ahead and try a new graphics card?

I forgot to mention that the monitors seem to only be recognizing a DVI connection.

MSI Z97 Gaming 3
Intel i7 4790k
Diamond Radeon HD 7850
2x8GB ram sticks (Corsair Vengeance)
Hitachi 2TB HDD
Crucial SSD 240GB
850W Corsair Gold Edition PSU
Atapi Blu-Ray player
Corsair H100 Liquid cooling

If you need anything else, just ask.

I mean it works with a DVI cable connected to the motherboard, although the mobo has ports for VGA and HDMI. I used this Graphics Card on my old build, so it may just be shot. If at anytime the Graphics card is plugged into the motherboard and receiving power from the PSU, the monitors will not register a connection at all. The graphics card fan still spins, but I read that doesn't mean it still functions.

I uninstalled the AMD drivers and reinstalled them using the disc included with the graphics card, but to no avail. It still blackscreens if the graphics card is getting power.

BUMP, don't really feel like buying a new card if I don't have to. :(

Try using the card on your motherboard's secondary PCI-E slot.

I've tried using both slots.

Odd... I would suspect the GPU, but since it worked fine on your previous build I'm going to say the motherboard is faulty. You can confirm this by borrowing a GPU from someone and trying to use it in your build. If it won't work, the motherboard needs to be replaced.

Yeah, the reason I upgraded was because I think a power surge knocked my old mobo out, so the gou probably got affected by that.
