Remember when we used to test RAM with a pencil eraser?
I was cleaning out my old toolkit and found a pack of those pink erasers. It got me thinking about how we used to fix bad memory contacts by rubbing them down. Last month, I had a stubborn desktop from 2012 that wouldn't post. Just for laughs, I tried the old eraser trick on the DDR3 sticks. To my shock, it actually worked and the machine booted right up. I thought that fix died with IDE cables and dial-up. It made me realize how much we rely on new tools and forget the simple stuff that still works. What's an old-school trick you still pull out sometimes when the fancy gear fails?
