Home Computer Crashed!

I got home after church today and went to get online with the home computer. It wouldn't start up, It was acting funny the other day and had a smell coming from it. I had planned on opening it up tomorrow and using the can air to dust it out. Well, I don't know what I am going to do now. I guess we'll call our computer guy to see if he can get it running again. Luckily my laptop works, I just have to drive to Mamaw and Papaws house, because I can't get the dial up to work. Ugh!!!!
