Is your computer slow, freezing, or taking forever to start up? Here is the good news: computer slow performance is almost never a broken computer. It is usually one of a few simple causes, and some of the fixes are free and easy to do yourself. Below we explain why your computer is slow, the free things you can try right now, and the two upgrades that make an old computer feel brand new. If you would rather we just speed it up for you, our check is free. We fix slow computers of every brand; see all our computer repair services.
Computer slow performance almost always comes down to one of five causes. The good news is that every one of them is fixable, and you can often spot which is yours from the list below. None of them means your computer is dying.
RAM is the short-term memory your computer uses to run programs. If you have too little for today's web pages and apps, the computer slows to a crawl when you open several things. Adding more RAM is one of the best speed fixes.
If your computer still has an older spinning hard drive, that is very often the real reason it is slow. Swapping it for an SSD, which is a much faster type of drive with no moving parts, is the single biggest speed boost most computers can get.
Many programs set themselves to launch the moment you turn the computer on. Twenty of them loading at once makes startup painfully slow. Turning off the ones you do not need is free.
Malware and junk programs run in the background and eat your computer's power. They are a very common cause of sudden slowness, and removing them brings the speed right back.
A drive that is almost full has no room to work, and the whole computer slows down. Clearing space often helps a lot, and it is free.
Before you spend any money on slow computer performance, try these free steps. They fix a surprising number of slow computers, and we would rather you save the cash if a free fix does the job.
It sounds too simple, but many people leave the computer on for weeks. A full restart clears out the clutter in memory and fixes a lot of slowness on its own. Try this first.
Open the task manager (press Control, Shift, and Escape together on Windows) and look at the Startup tab. Turn off programs you do not need at startup, like chat apps and updaters. Your computer will boot much faster.
Delete files you do not need, empty the recycle bin, and remove programs you never use. Giving the drive room to breathe can speed things up right away.
Run a scan with your built-in security software. If it finds and removes junk, your computer may speed up immediately. If you are not sure how, we are happy to check it for free.
If the free fixes are not enough, two upgrades do the most for speed by far. They are affordable, and they make a slow old computer feel brand new, often for years more of use.
Moving from an old spinning hard drive to an SSD is the single best thing you can do for a slow computer. Programs open in seconds, the computer starts up fast, and everything feels snappy. It is the upgrade we recommend most, and we keep your files when we do it. If you are worried about your files during any speed work, see our data recovery page; your data is always safe with us.
If your computer struggles when you open lots of tabs or programs, more memory is the fix. See our computer RAM upgrade service to find out if yours can take more and what it costs. We check for free whether memory is actually your bottleneck before you spend.
If you saw a popup that says "Windows has detected that your computer's performance is slow," stop and read this. That message is fake. Windows does not show popups like that, and it is a scam designed to scare you.
Two common situations have their own answers. If your computer got slow after an update, or it is simply old, here is what is behind the slow computer performance.
Sometimes a Windows update runs background tasks for a while, or changes a setting, and the computer feels slow for a day or two. If it stays slow, an update can also reveal that your computer needs more RAM or an SSD to keep up. We can tell you which it is.
Older computers slow down as programs and websites demand more than they used to. This is exactly where an SSD and a little more RAM work magic, often making a five or six year old PC feel new again for a fraction of the cost of replacing it. If the battery is old too, a failing battery can sometimes make a laptop act strange. See our laptop battery replacement page if your laptop also dies fast.
Macs slow down for the same reasons: a full drive, too little memory, or software clutter. If you have a slow Mac, see our Mac computer repair service for the Mac-specific help.
The price to fix computer slow performance depends on the cause, and many fixes are cheap or even free. The diagnosis is always free, and you approve any cost before we start. Here is a general guide.
| Service | What It Covers | Price Range |
|---|---|---|
| Free speed-up diagnosis | Find the real cause of the slowness | $0 |
| Cleanup and tune-up | Startup, junk removal, settings, disk cleanup | $49 to $99 |
| Malware removal | Remove malware and junk software | $79 to $149 |
| SSD upgrade (with your files moved) | New SSD plus moving your files over | $129 to $249 |
| RAM upgrade | More memory, by model | $69 to $199 |
For the exact price on your computer, call (703) 594-9339 or request a quote online.
Almost always yes. For most computers, a tune-up or an SSD and RAM upgrade costs far less than a new machine and makes the old one fast again. If your computer is very old or failing in other ways, we tell you honestly that your money is better spent elsewhere.
Most slow-computer fixes are quick, and many are done the same day while your files stay right where they are.
Why is my computer so slow all of a sudden?
Sudden slowness is most often malware or junk software running in the background, a nearly full drive, or too many startup programs. A restart and a malware scan fix a lot of cases. If it stays slow, the cause may be too little RAM or an old hard drive, and our free check tells you which.
What is the best way to speed up an old computer?
Adding an SSD, a fast modern drive, is the single biggest speed boost, and adding more RAM is second. Together they often make a five or six year old computer feel brand new for far less than buying a new one. We test what your computer needs first so you do not overspend. See our RAM upgrade service for memory pricing.
Is the "Windows has detected your performance is slow" message real?
No. That popup is a scam, not a real Windows message. Windows never shows a popup like that. It is a fake browser popup trying to get you to call a fake support number or install fake software. Do not call it and do not install anything. Close the tab or restart, and if it keeps returning, you may have junk software we can remove.
Can I fix a slow computer myself for free?
Often yes. Restart the computer, turn off programs you do not need at startup, clear out space on a full drive, and run a malware scan. These free steps fix a lot of slow computers. If they are not enough, the cause is usually RAM or an old drive, and we can help.
Will a virus make my computer slow?
Yes, very often. Malware and junk software run in the background and eat your computer's power, which is a common cause of sudden slowness. Removing them usually brings the speed right back. We remove malware safely and protect your files.
How much does it cost to fix a slow computer?
The diagnosis is free, and many fixes are cheap. A cleanup and tune-up runs $49 to $99, malware removal $79 to $149, an SSD upgrade with your files moved $129 to $249, and a RAM upgrade $69 to $199. You approve the price first, and many visits end at a cheap or free fix. Get a free quote or call (703) 594-9339.
My computer got slow after a Windows update. Why?
An update can run background tasks for a day or two, or change a setting, which feels slow for a short while. If it stays slow, the update may have revealed that your computer needs more RAM or an SSD to keep up with newer software. We can tell you which it is at the free check.
Is it worth fixing a slow computer or should I buy a new one?
Usually worth fixing. A tune-up or an SSD and RAM upgrade costs far less than a new computer and makes the old one fast again. If your computer is very old or has other problems, we tell you honestly when a new machine is the better buy.
