No Monitor image after installing GPU

So this is my first build ever, been basically using newegg YouTube channel as a guide, and answering specific questions with Tomshardware google searches. Now I have a problem that hasn't turned up results in a search, at least not good ones.

So here goes: I put together everything EXCEPT the GPU and it's been running great for one day. I installed Windows and started up my Steam library downloads. Today I put in my GPU (AMD 7870 Sapphire non-OC version) and now I have no image. Everything starts up fine, the fans are going (GPU fans too) and I've double- and triple-checked my cables...I'm 99% sure nothing is hooked up wrong.

Some specifics: My monitor is DVI or VGA only, no HDMI option. I only have a VGA cable so I've got the monitor hooked up to only the motherboard since the 7870 doesn't have a VGA output. I'm wondering if this is a problem, does the monitor HAVE to hook up to the GPU? I feel like I should still be able to use the motherboard VGA to output images...maybe it's a driver problem? There is a Sapphire GPU driver CD that I haven't installed yet. I'm gonna try that next and will edit this.

If anybody has any other ideas, they would be greatly appreciated.

You have to connect your monitor directly to the gpu (when not using Virtu technology).

Thanks...just went to the store for an HDMI-to-DVI cable...working just fine now. Not sure why I never knew this, thanks for the help.
