2) What rating is your power supply?
3) Try without the HDD attached.

1) i'm using the latest beta. fresh install from your installer if that's what you mean ?
2) power supply should be ok (5V 2A)
3) i don't have problems without the drive attatched. but it was working fine before beta 1. it's an external powered usb drive going trough an external powered usb hub to the pi. Nothing else attached at the moment.
