pc startup problem

[wreksta]

hi all i have an orange live box
the problem is if i have the ethernet plugged in to the live box during start up
i get a quick flash of a blue screen then the pc restarts all the time unless i do as below

so i have to pull out the ethernet lead from live box until windows is started then
plug it back in to use the internet
and to be honest its getting a pain in the a*se
could any1 shed some light on this please

if any good i have a amd 64 3200
and a gigabyte board

Disable any option to boot from a network connection? e.g. PXE boot etc...
