Advice : Mobo and GPU

[qmrneo]

The problem that I found was that by default the mobo do not detect the "Native IDE" type the first time I connected the SATA HDD. I guess It was RAID or AHCI by default in BIOS. Also when I Checked from BIOS the HDD space it shows as 0 MB on autodetect. Then I changes the OnChip SATA type to Native IDE manually and it worked.

No, you're still not understanding. AHCI drives do not necessarily appear in your BIOS setup because they are initialized later (it depends on exactly when your mobo goes into the setup screen). The reason you could not originally install Windows XP is because Windows XP cannot detect AHCI drives without additional drivers.
