Secondly, yell, "GOSH MOM, JEEZ WHAT THE HELL!", and make her feel bad. Make sure you mention the loss of school/work documents and and/or pictures of friends/family. If you make her feel guilty enough, start suggesting, although not directly, that you get another computer for yourself to use to ensure that this never happens again. "IF I HAD MY OWN COMPUTER THIS WOULD HAVE NEVER HAPPENED! GOOOOOOOOSSSSSSHHHHHHH JEEEEEEEEEEEZZZZZZ! I CAN'T BELIEVE IT! I STILL LOVE YOU MOM, BUT C'MON!? WHAT WERE YOU THINKING!"
