Upgrades and repairs that earn their keep
Most old PCs aren't slow because they're old. They're slow because of one mechanical hard drive, too little memory, or a fan full of dust. Each of those is an afternoon and a modest amount of money to fix, and the difference is dramatic.
Guides
The order to do things in
- Back up. Before anything else. Twenty minutes, one external drive.
- Clean it out and check what's running at startup. Free, and it fixes more than people expect. The speed-up guide.
- If it has a spinning hard drive, replace it with an SSD. The single biggest improvement available. The SSD guide.
- If it has 4GB of memory, add more. Worth it if you live in browser tabs. The memory guide.
One 2026 note: the memory-chip shortage has made SSDs and RAM cost more than they did two years ago. The SSD swap is still clearly worth it on a hard-drive machine. The RAM upgrade has become more of a judgment call, and the guide says where the line is.
