Notice when it feels slow
- If startup is the only slow period, too many login apps are likely involved.
- If one browser is slow, test a different browser and close unused tabs.
- If everything freezes, check Task Manager on Windows or Activity Monitor on Mac for unusually high CPU, memory, or disk use.
Check storage, updates, and unwanted software
- Keep meaningful free space available so updates and temporary files have room to work.
- Install operating-system and browser updates, then restart.
- Run the built-in security scan. Remove unknown browser extensions and programs, but do not use aggressive registry cleaners.
Know when hardware matters
- An old mechanical hard drive can make a healthy computer feel painfully slow; an SSD upgrade can be significant when the computer supports it.
- Too little memory causes constant switching between programs and disk storage.
- Heat, dust, a failing drive, or a noisy fan can indicate a physical issue that remote cleanup will not solve.
Stop guessing when the problem keeps coming back
Ask for a diagnosis if performance changed suddenly, the disk stays at 100 percent, pop-ups appear, or you are unsure whether an upgrade is worth the cost.
