I've (well my missus has) got win 7 64 bit running on a core i5 with 4 gig and a 1 gig vid card.

Problems??
Well, there is a big problem with her Iphone/Ipod.
Once she plugs it in, nothing else works! (USB related)
No Hard Drive, No Scanner, no printer. Yet the mouse works... go figure.

If you reboot they start to work again (at a USB 1.1 standard)

The fix? Shut down, remove battery, restart. Works untill she puts the damn Iphone back in again.
