hi, I'm havin issues ATM were by I can't seem to install any type of os. It appears to hang on the scrolling bar on vista, if I try xp it sometimes gets further but have seen it come up with a I/O error. I have changed the board and still have the same problems. Could it be a hd issue? Or optical drive? As I have seen it on both boards were sometimes in the bios it shows my dvdrw as all gobbly goook on the description for it. I'm running a q9450 chip with a maximus II P45 board and raptor x hd
