I installed a new asus motherboard and new 160g drive on my desktop, I left the old drives in the machine but installed a new version of XP on the new drive and made it the boot drive. Nothing else was changed. My desktop now takes between 3 and 5 minutes to get from the bios info screen (instant) to the XP loading screen, after that the computer runs normally at a good speed. How can I track down what is making the boot process take so long. The shop where they replaced the motherboard and new drive were of no help after looking at the physical configuration.
