Monitor goes to sleep after completion process during Windows7 install

[sdmf508]

Hello everyone, I hope someone here can help me out with this strange problem I am running into. I just built my first computer build today, & I must say that everything has seemed to go quite smooth. The problem that came up though, is after installing Windows 7 home premium 64bit OEM to my HDD (it went through the whole copying files, expanding files, ect.). Upon restarting itself, it goes to the Windows startup screen & the logo appears normally for a few seconds & then the monitor goes black/goes to sleep. Everything inside the computer is still running at this point I should add. There's no debug code on my motherboard so I'm assuming everything is fine inside. I'm using a HP w2207 monitor with a DVI connection to a ASUS HD4870 GPU. Any input on this strange situation would be greatly appreciated!

(My ghetto hd4870 has 2 DVI on it if that's any help.)

Thanks in advance.

Welcome

Did you go into Bios setup and make sure that that video is set to PCI-E as 1st choice

I don't recall seeing anything like that in the Bios, but I'll add that to my list of things to try for tomorrow. I've read in some other forum that it could be some "VGA fallback", where it just defaults to VGA? If this is the case, what would I do to get DVI to work? Just download the necessary driver?

Thanks for the suggestion by the way & sorry for the additional questions lol.
