How do I speed up my computer right now?

Release the memory your browser tabs are holding, then check whether any single process is pinning the CPU. Between them those two cover most immediate slowness, and both take under a minute.

Is it my computer or my internet that is slow?

If web pages are slow but opening local files and applications is fast, it is the connection. If everything is slow including things that never touch the network, it is the machine.

Why is my computer slow even though it has good specs?

Specs describe capacity, not what is consuming it. A powerful machine running out of memory behaves exactly like a weak one, and a fast processor still throttles when it overheats.

How do I know if I need more RAM?

Check whether the system is paging to disk while you work. If it is, more RAM helps enormously. If it is not, more RAM changes nothing at all.

How do I speed up my computer? Twelve questions, answered directly

The specific questions people ask about slow computers, each answered in a paragraph. No preamble, no twenty-step checklist — find yours and act on it.

Answers only. Find the question that matches yours.

How do I speed it up right now, in under a minute?

Release what your browser tabs are holding. On a machine with 8 GB of RAM or less this is usually the whole problem, and unlike closing tabs it costs you nothing — the tab stays where it is.

How do I know what is actually causing it?

Open Task Manager (Ctrl + Shift + Esc) or Activity Monitor and watch it while the machine is slow, not while it is calm. Whichever of memory, CPU or disk is pinned is your answer.

Is it my computer or my internet?

Open a large local file or an offline application. If that is fast and websites are slow, the machine is fine and the connection is not.

Why is it slow when the specs are good?

Because specs are capacity, not usage. A 32 GB machine that has filled 32 GB behaves exactly like an 8 GB machine that has filled 8 GB. Fast processors throttle when hot, too.

Do I need more RAM?

Only if you are currently running out. On a Mac, the Memory Pressure graph tells you directly — yellow or red means yes. On Windows, compare committed memory to installed memory in Task Manager's Performance tab. If you are not swapping, more RAM does nothing.

Should I buy an SSD?

If the machine still has a mechanical hard drive, this is the single biggest improvement available and it is not close. If it already has an SSD, check free space instead.

Do I have too many tabs open?

The number matters less than what they hold. Six heavy web apps cost more than forty text articles. Measuring is the only way to know which of yours is the expensive one.

Will closing programs help?

Only the ones actually using something. Closing a text editor to free 40 MB while a browser holds 4 GB is not a fix.

Is a virus making my computer slow?

Possible, and less likely than the ordinary explanations. Run one full scan with the security software already built into your system. If it is clean, move on rather than installing more scanners.

Do cleaner apps work?

No. Nothing they do addresses memory pressure, disk health or overheating, and the category has repeatedly shipped adware.

Why does it get slow again after I fix it?

Because the causes refill — tabs accumulate daily, startup programs return after updates. Keeping it fast is a different job from making it fast.

Is it worth fixing, or should I replace it?

A machine that boots from an SSD, has free disk space and is not swapping is fast enough for almost everything, more or less regardless of age. Find out which of those three is missing before pricing a replacement — two minutes with a task manager answers it.
