faster boot time

You may want to take a look at all of the devices that are set to start automatically with Windows, (i.e., Microsoft Office Shortcut Bar, MSN Messenger, etc.). If you do not use these devices frequently, try to disable the auto startup features. This will reduce the number of applications the OS has to start.

You may also want to defrag your hard drive. Often times, a heavily fragmented hard drive causes the OS to take longer becuase it has to hunt for the data it needs.

You may want to see how much of your resources the system is using during a normal boot. If there are not enough free resources, you may need to upgrade. That doesn't seem like it would apply to you though. Also, check and see how much free space you have on your hard drive. A good amount of free space is at least 20%. This gives the system sufficient space to work with, and will help it work faster.

I hope this information helps.
