With 80G SSD dick everything (Windows 7) work great, but after replace it with new HDD ( Hitachi HDD 5K750 750GB) system mostly stops in Bios phase (sometimes with only _ in top left corner or black screen. Sometime I can enter into BIOS, but system hang up after few movement thru menus. If system go over BIOS, Windows work without problem.
I check with restored Win7 from SSD and with fresh Windows (delete all partition before installation).
