This is my first post...looked through the forums & find it necessary to make a new thread!

Alright, so i followed this guide to install on iatkos v7 on my build:

http://www.insanelymac.com/forum/ind...owtopic=206434

It worked great when i only had the GTS 250 gpu.....but i recently added a GTX 260 to the system as the main GPU, and the 250 is now a dedicated physX card. I reinstalled iatkos v7 and changed only my video driver selection (to support the 260). After installation, it boots fine into OS X, but, when I restart...i select my OSX disc from the bootloader & it goes to the gray screen and then to a black screen....& once in a while i see the colored apple circle...

fyi, the install is on a separate drive...

Maybe something is messed up with the video drivers?

Thanks for the input!

Ben
