Crash!

So our computer took a dive this week - I've been without the Internet for 3 whole days and I feel like I've lost a limb! I was online and all of a sudden the screen went bright blue and the words ....BEGINNING MEMORY DUMP.... flashed across the screen. Yikes! I quick shut it all down and tried to restart, but all it would say is "Inaccessible Boot Device. Start Error Screen." Sucks.....And even worse, I think many of the pics I was looking forward to posting have been lost forever. So I am at my mom's real quick doing some emailing and this quick post. Hope to be back up and running soon!
