What can one put in front of living room window instead of?

I get to the window that asks me to select windows xp media center edition but i can never click it before it goes to black and goes back to telling me to start it again. I do not have a back up cd, I'm really bad at this, I need detailed instructions not using computer words I don't know.
well your being a little confusing here but I'll try any way, can you actual log in to your account?
I thought something else would happen lol.
Thanks.

DVD to iPhone Converter for Mac is a Mac DVD to iPhone converter designd for Mac OS users to convert movie DVD to iPhone MP4 video and M4A audio.

An upgrade just upgrades the Windows files...keeping all your data files and installed programs on your computer.
An install you wipe your hard drive and install a fresh copy...losing any installed programs or data files you have saved.
or is this all happening when windows is starting up? if you can log in you should try going on line and downloading some antiviral programs like spy-ware doctor or a squared ( both free programs) if you can't log in then try booting in safe mod.
you can do this when you first turn on your computer and the screen is just black and whit and says what ever brand of computer you have with a loading bar at the bottom, ones the bar gets about half way full hit the f-8 or f-9 a few times then the screen should go totally black for a min.

Video Converter for Mac is a professional Mac Video Converter which can perfectly convert video on Macintosh.

with a flashing whit under score then you should try hitting f-8 or f-9 a few more times. then a screen should come up with a bunch of different boot options use your arrow keys to highlight the one that says safe boot with networking, or if you don't wont the internet just safe boot. now hit enter. log into you account and try to work out the problem from there if you can't figure it out on your own then you should probably take it to a computer doctor. hop this helped :)
easiest thing to do when you see that screen is press the f8 key on your keyboard.
then use the up and down arrows to find the option that says "boot into safe mode"
if after starting in safe mode the computer restarts on its own again, the issue is something you will need to bring into a computer store to take a look at. always better safe than sorry..

FLV converter for Mac is also a flash video editing tool.

based on the fact you seem to be in what we call a 'reboot loop', trying to boot into safe mode is the easiest way to test it out
you'll need a disk to fix this
I want to install Windows 7 RC on my test computer and I saw that there were two options.
Upgrade and a Clean Install.
This might sound like a dumb question, but is there any difference?
Thanks!
I knew about the obvious one - keeping files and folders.
