5 Things to Check Before Replacing a Slow Computer
A slow computer does not automatically mean it is time to buy a new one.
Before replacing an older PC or laptop, it is worth finding out why it is slow. Sometimes a cleanup, repair, memory upgrade, or storage upgrade can extend its useful life. Other times, replacement really is the smarter investment.
