Okey, sorry for VERY bad english, i have used "Google translate" and convert from Swedish, hope u enjoy

Right now running a PC with Windows 7 and a partitions with OS X 10.5.6 (IPC). Today got hold of a retail SL 10.6 disc trought school, and want to make a new clean install with this.

Does Google around and literally drowned in the guides. Know that I had serious problems installing the right drivers and stuff like that last time. Now it is a new approach when it is retail, and I have no idea how.

Someone who has link or can write to a guide that could fit my pc:

Windows 7 RTM

Intel Q9550
Gigabyte EP45-DS3L
OCZ reaper 4GB 1066MHz DDR2 (Satan's mass settings in the BIOS for these, so would rather not have the BIOS reset, as I way to show installations do)
Sapphire Radeon HD4890 1GB
Creative X-fi Fatal1ty
Networks are running internally.

Someone who can take strength and provide me with some step-by-step? Can not hold my breath anymore!
