    I dont just mean different computers doing different things. I mean the same computer will do something (talking about during bootup process mostly) one way and under the same circumstances and conditions it will do it differently the next time you boot.

    For example:

    My friends computer will bootup from cold and the sound will not work and he has to reboot for the sound to work.

    whats up with that?

    Welcome to TSG!
    Windows boot process is pretty much cast in stone as far as the sequence of load. Where problems occur is if there are conflicts in hardware wanting to share what is called and Interrupt (IRQ). If your friend is having the problem mentioned then a good place to start would be to go to Start\run and type in msinfo32 then enter. Once you reach the msinfo32 display click plus sign to open "Hardware Resources" then click Conflicts\Sharing. You should find your audio adapter sharing an IRQ with another hardware item. Many times these hardware items will use the IRQ together and not have a problem but if they attempt to boot together one wanting the IRQ at the same time as the other one may not end up working properly. If that is indeed your case then you need to research the items that are residing on the same IRQ and see if they can be moved to another IRQ so they do not fight eachother a Boot.

    Note: Msinfo32 will open a new realm to you as you investigate whats in it.

    Here is an article that explains the Windows Boot Process in Detail. It is written for Win9x os's but much of it still applies to other OS's. As you will see the actual boot process is quite structured.


    PS: Here is Thread that is running right now that MTBird is requesting to look at the IRQ's for a sound card problem.
