Computer Problems

Everytime I write a post it won't print and I can't understand why. When I publish it gives the title but no post. This just keeps happening and I can't get it working right. I have written 5 filler posts and when I publish it the title is all that comes up and the next one just replaces the last one. The intire body of the post is gone and I can't get it back. I think I'll just go to bed and let it alone until morning.
