Your computer is driving you crazy. Everything takes forever. Programs take minutes to open. The browser freezes. You click something and wait. And wait.
Before you assume it’s broken, before you call anyone, and before you think about buying a new one โ try these steps first. A surprising number of slow computer problems are completely fixable without spending a dime.
I’m Sean from TechCrazies, and this is exactly what I check first when I arrive at a customer’s home on the East End.
Step 1: Restart It. For Real.
I know this sounds too simple. But you’d be amazed how many people leave their computer running for weeks or months without a proper restart. Sleep mode is not the same as a restart.
When you restart your computer, it clears temporary files, flushes the memory, installs pending updates, and gives everything a fresh start. A computer that’s been running for 30 days without a restart is carrying a lot of baggage.
Do this first: Click Start โ Restart (not Shut Down, not Sleep โ Restart). Let it fully complete. Then try using it again.
If it’s noticeably faster after a restart, that tells us the problem is software-related, not hardware. That’s good news.
Step 2: Check How Much Storage Space You Have Left
This is the second most common cause of a slow computer that I find when visiting customers.
When your hard drive gets too full โ typically under 10-15% free space โ your computer starts struggling. It uses your hard drive as temporary memory (called a page file or swap file) and when there’s nowhere to write temporary data, everything slows down dramatically.
On Windows: Open File Explorer โ click This PC โ you’ll see your drives listed with a bar showing how full they are. If it’s red or nearly full, this is your problem.
On Mac: Click the Apple menu โ About This Mac โ Storage โ Manage.
Quick fixes to free up space:
– Empty your Recycle Bin or Trash
– Clear your Downloads folder โ most people download things and never delete them
– Remove programs you no longer use
– Move photos and videos to an external drive or cloud storage
If your drive is nearly full and cleaning it up is overwhelming, this is something we can help with quickly on a house call.
Step 3: Check What’s Running in the Background
Your computer might have dozens of programs running silently in the background eating up memory and processing power โ programs you don’t even know are there.
On Windows: Press Ctrl + Shift + Escape to open Task Manager. Click the CPU column to sort by usage. If something is using 80-100% CPU consistently, that’s your culprit.
On Mac: Open Activity Monitor from your Applications โ Utilities folder. Same idea โ sort by CPU.
Common background culprits:
– Antivirus software doing a full scan
– Windows Update running in the background
– Cloud backup programs syncing large files
– A browser with 40 tabs open
– Old programs that launch at startup and never get used
Step 4: Check How Much RAM You Have
RAM is your computer’s short-term memory โ it’s what holds everything you currently have open. If you don’t have enough, your computer constantly shuffles data to the hard drive which is dramatically slower.
Most tasks today need at least 8GB of RAM. If you have 4GB or less and you’re running Windows 10 or 11, you’re going to feel it.
On Windows: Press Windows key + Pause/Break โ look for “Installed RAM”
On Mac: Apple menu โ About This Mac โ look for Memory
If you have 4GB or less, adding more RAM is often the single best upgrade you can make โ and it’s relatively inexpensive. On many laptops and desktops it’s a straightforward upgrade.
Step 5: Check for Malware
Viruses, malware, and unwanted programs are a surprisingly common cause of slow computers โ especially on Windows machines. Some malware runs quietly in the background using your computer’s resources for things like cryptocurrency mining or sending spam.
On Windows: Windows Security (built into Windows 10 and 11) โ Virus & threat protection โ Quick scan. This is free and catches most common threats.
For a deeper scan, Malwarebytes has a free version that’s excellent. Download it from malwarebytes.com directly โ not from a pop-up ad claiming your computer has a virus.
On Mac: Macs are not immune to malware despite popular belief, but they’re less commonly targeted. Malwarebytes has a Mac version worth running.
Step 6: Check Your Browser
If the slowness is mainly in your web browser โ pages loading slowly, the browser freezing, videos buffering โ the browser itself is often the issue rather than the computer.
Things that kill browser performance:
– Too many browser extensions installed
– Cache and cookies built up over months or years
– Too many tabs open simultaneously
– An outdated browser version
Quick fix: Clear your browser cache. In Chrome: Ctrl+Shift+Delete โ select Cached images and files โ Clear data. In Safari: Preferences โ Privacy โ Manage Website Data โ Remove All.
Also check your extensions โ go to your browser’s extensions/add-ons page and remove anything you don’t recognize or actively use.
When These Steps Don’t Help
If you’ve tried all of the above and your computer is still dragging, the issue is likely one of these:
Failing hard drive: Older mechanical hard drives slow down significantly as they age or start to fail. Replacing it with a solid-state drive (SSD) is often the best upgrade you can make to an older computer โ it can make a 5-year-old machine feel almost new.
Overheating: Dust buildup inside a laptop or desktop can cause it to overheat and throttle performance to protect itself. A cleaning and fresh thermal paste can fix this.
Too old for the software: At some point hardware is simply too old to run modern software efficiently. If your computer is 8+ years old and all of these steps haven’t helped, it may be time to talk about a replacement.
