Ram: 2x2 GB : 4 GB Corsair 800 MHZ

OK, The installation process was OK, at the end it shows SUCCESSFULLY INSTALL, Then i run the Combo Update i download from apples web, without restarting then i run multishit so far all great, after that i reboot my machines and the sound was enable. BUT a few minutes later it pop up a windows ( Kernel Panic message FU&% NO!!!) I shut it down and reboot and this msg appear ¨You need to restart your computer, Hold down the power button for a second...¨ , thats number one, number TWO is that i cant setup my dual monitors! Guys im going crazy...IDK what else to do...i have read the wiki page and other ones but hardly find some info for my configuration, maybe is just me that im newbie to this but i just hope that one of you can help me with this. thanks for your time bye
