Which motherboard have you got ?
I am just wondering if maybe after the re install that it needs the drivers updating, especially if its a VIA chipset on it.
Maybe the IDE controllers arent using the best drivers but they are good enough for the CD rom and eventually the hard drive

I am clutching at straws here of course but there appears to be something missing in this new installation to what was on the old one
