Computers: speed, memory and buying well
Diagnose a slow computer properly, understand what memory and storage do, and buy a laptop on the specifications that change daily use rather than the ones on the box.
A computer that needs a long minute to become usable after you log in is rarely worn out. It is usually clogged, short of memory, or busy running something you never chose to install, and telling those apart decides whether you spend an afternoon or several hundred on a replacement. Speed, memory and buying decisions are where most people spend money they did not need to spend, usually on the wrong part.
If the machine in front of you is the problem, work through the causes of a slow computer in the right order, since the fix depends on whether the drive, the memory or the software is the bottleneck. If you keep hitting a wall with a video call and a pile of browser tabs open, settle how much memory you actually need before you buy any. Only then reach for a laptop buying checklist that separates the specifications you feel every day from the ones printed on the box. If the slowdown arrived suddenly alongside pop ups, treat it instead as a cleanup job.
For a small business the sums change, because a slow machine is paid for daily in staff time, so a replacement that looks extravagant for one person often pays for itself across a team.
