components:
gigabyte g31m-es2l rev 2.0
gigabyte gv-n84s-512l nvidia geforce 8400gs
e6600 cpu
2gb corsair ddr2
500gb sata hd

have been trying to install using this guide:
=****************>> INSTRUCTION IS NOT COMPLICATED - ITS V - Mac OS 10.6.5 on G31M-ES2L

if i switch the pc with no os......the hdmi(with hdmi converter),dvi and vga all work.
i dont have a monitor so i have been using my 42" led lcd tv....has vga and hdmi.

the following is when its connected to the tv via hdmi.
when i install myhack onto the memory stick.....if i tick the graphics enabler....it installs ok but when i restart i just get a black screen.
if i install myhack without the enabler it.....it restarts fine but in the graphics card part.....the card isnt recognised.

if i leave the enabler off and install nvenabler64.kext then i can get vga through the vga and dvi ports......can also change the resolution upto 1280x1024 i think it is.
also the graphics card is recognised and it can see the 2 displays and allows me to select 1080p for the hdmi to tv.....but if i switch it off.....unplug the vga and just have the hdmi in......i just get a black screen.
i have also tried a dvi to hdmi adaptor but the results are the same.
the tv flashes up its own display(like when u change channel) and says 1080p @50hz so it seems like a signal of sorts is getting to the tv.

any ideas or help would be greatly appreciated.
thanks.

tried nvenabler, natit, and nvinject
all work though vga and the card details are shown in the system info part but if i try dvi out through a hdmi adaptor or just hdmi out.....i get the black screen again.....
anyone?
