Just upgraded a pc..its a Gigabyte GA EP45 mobo, intel core 2 duo cpu and
XP.

When it boots up it seems to go through part of the sequence twice....

This is what happens when it boots:-

Beep

Gigabyte display (where one can tab for Post or esc for enter Bios etc)

black screen

Beep

Gigabyte screen again (where one can tab for Post or esc for enter Bios etc)

list of text

then Windows sequence

and finally all ok after 1.5 mins

any ideas why it should pull up the Gigabyte screen twice?

wonder if its to do with the motherboard, cpu or Operating system?
