Computer Crashed!

My computer crashed! We have a Dell XPS All in one...only 3 years old. It's been slow & freezing on me. A few weeks ago I realized it gets real hot on top, and then realized that I never hear the internal fan run.
Thankfully, Bill bought me a laptop for our anniversary. Thankfully it was still under warranty and thankfully the people at Dell are terrific. I chatted on my laptop with a woman named grace, who ordered me new parts. And at this time, Mr. Jim has opened up my computer and a new one and began transferring all the important memory parts onto the new one. madison took one look at ours and said "Mom, theres the fan & it's covered in dust...I bet that's why it wasn't working right!". Mr. Jim agreed. As the girls and I looked on, we noticed that a couple of the tiny parts looked like electromagnets (the science topic for the week). Mr. Jim gave us a quick talk on the use of electromagnets in computers...pretty neat. Then madison saw a little Greek symbol on one of the parts. Madison reminded me that it was the symbol for Ohm...the measurement for resistance. Isn't it just like God to take something annoying, like my computer & turn it into an interesting science lesson...I love when that happens!
