Trouble with black screen.

[SparkPlug'd]

Here's my specs:

Asus P5E

Sapphire ATI 4850, 2 DVI ports, 1 S-Video

G-skill 4GB

Pentium D 920

 

 

Here's my problem:

I've tried almost every Snow Leopard distro, and all end up the same: I get a black screen when I try to boot into them.

Basically, the bootloader comes up, and then I select Snow Leopard, and then it goes to black screen. I've tried using -x and -v, but I still end up with the black screen. I've also tried --Graphics-enabler and disabler to no avail. Now I have a retail disc and I put it on the USB using the myHack method. When I try to boot the USB, it also gives me a black screen.

 

At the moment, I have a temporary Leopard distro that I'm using, but I'd like to use Snow Leopard, with full drivers and everything. If you need more information, I'll be happy to specify.

 

Thanks.
