System wont reboot - crashes before posting HD info

Hey all,
First post here - wahoo

Anyway, I have a home built system that I've had for years, just slow partial upgrades all the time to the beast it is now!!

Anyway, just moved from the UK to Oz and so stripped my machine down and brought it here in pieces in hand luggage.

Rebuilt the system here and I'm having problems with it
(it's also got two new HD's in it that I bought just before the UK that I've now set it up on and one of which I'm using as the boot drive).

Anyway, the machine starts fine, press the power and it'll boot up with no problems and work fine. If I try to restart it however it reboots, does the memory check fine (I've also tested this with Memtest86+ and left it running for 9hrs and no errors), posts the Timing for the memory, then just before it should post all the HD info, it hangs, then reboots after a couple of seconds.

This happens consistantly.
Anyone got any ideas what could possibly be causing this?
