Ok so we have a couple of problems ...
Problem one is that the video card is problem number one for OSX - this card came way after OSX Snow Leo stopped getting updates for video kexts. So this will not work w SL.
Problem Number two - your posted to the Guides section and as its not a guide I moved it to this installation section.
Problem number 3 - you method of the install using unapproved installer is not going to work nor get responses. In fact you could get banned.
SO I suggest you read the rules of this site -

Now this motherboard you have is some what of a problem MotherBoard for SL so we know this going forward.
But all of the hardware specs are good sound network CPU and the HD3000 video. So remove the 570 video card and try again. Of course we need to have the BIOS settings in the correct selections AHCI - Video etc.
As you have a sandy bridge system you will need to install the update helper once we get to osx 10.6.3 or 4...
here is a modified installer in outline steps.

How to do a sandybridge cpu w compatable hardware OSX hack 10.6.8 build. jester969
Typical installation steps are:
1) iBoot + Disk Utility + install Snow Leopard DVD (perform install via DVD) reboot
2) iBoot + Installed OSX HDD (boot with iBoot and loading OS via newly installed HDD) - get welcome screen
3) Run Update Helper and Reboot?
4) iBoot + Installed OSX HDD, run combo update 10.6.8 , DO NOT reboot
5) Run Multibeast and select option which are required to your board and run System Utilities.
6) Reboot w/out iBoot
Audio/Ethernet/DSDT
DSDT and BIOS firmware must match to the corresponding number
As you do not have a DSDT file for this MB we will need to install w/o DSDT and choose the options in MultiBeast for the motherboard.
Ok so here are some other links I found on your hardware.

this link uses BridgeHelper which is not designed for Snow Leo but for Sandy Bridge MB w Ivy Bridge CPU's on Lion and ML.
Do note that he uses the command switch for Bus Ratio= - he also uses the older iBoot Legacy CD to install with.
Also do a search w Google on thise terms ASUS P8P67 LE + Snow Leopard
Here is one from our site -

Also enter your motherboard
Asus P8P67 LE into the search box on the top of the page at the website TonyMacX86 and you will get a lot of hits from users that have used this board. Some w Lion SL or ML.
Read and make notes of topics are related to your install and hardware.
