I want to install a new clean OS of Windows XP on my computer.

How I usually do it is to boot from the OS CD then format the Hard drive then install a new Windows.

To do this i usually would change the priority boot sequence and put the CD-ROm Drive first… but this time it doesn't work?

I have the motherboard
INTEL D865GLC

It happens like this on all of my computers running this motherboard.

The computer will boot off the CD ONLY if there is no operating system currently on the Hard Drive.

But there is and and want to REdo it.

Is there a way to fix this, or is there another way to format the hard drive and then install a new OS?

My computer has been running slow lately and my friends asked me if I had done a “clean up” on it. I haven’t, they say when I do it, my computer will run faster. ONLY PROBLEM: I have a ton of pictures/videos, I don’t want to lose them! What do I do?

but i dont have or i lost the windows xp cd… any other way???

Not the internet browser history, I want to be able to clean the history off my computer when my OS is Windows Vista. I want to clear the recently changed, recent items, etc. How can I do this without using a program or downloading stuff?
How does clearing the internet browser clean my computer Windows search, etc?

I have 5 children and they seem to keep adding all these programs that think they need to run in the start up. Therefore it takes a long time for our computer to start all the way up.
