Is your computer taking forever to boot? Are apps freezing while you are trying to work? You are not alone. In Canning Vale and across Perth, slow computer performance is the number one reason people call me for help. Windows 10 and 11 are powerful, but they accumulate clutter quickly.
Before you get frustrated and buy a new laptop at JB Hi Fi, try these 10 troubleshooting steps to reclaim your speed instantly. These are the same professional grade checks I perform at my workshop.
1. Audit Your Startup Programs
Many apps like Spotify, Steam, or Zoom force themselves to start the moment you turn on your PC. This eats up your RAM before you even open a browser.
2. Switch to Best Performance Power Mode
By default, laptops are set to Balanced mode to save battery, which actively throttles your CPU speed. If you are plugged into power, this is unnecessary.
Go to Settings > System > Power & Battery and change the Power Mode to Best Performance. You will notice windows and menus feel snappier immediately.
3. Clean Up Temporary Files
Windows stores cache files that are supposed to help, but when they grow to 20GB or more, they do the opposite. Press Win + R, type %temp%, and delete everything in that folder. Do not worry—Windows will not let you delete anything actually in use.
4. The HDD vs SSD Factor
If your PC is more than a few years old and still uses a mechanical Hard Drive (HDD), no software fix will truly make it fast. Upgrading to a Solid State Drive (SSD) is like moving from a bicycle to a Ferrari. It is the single most effective way to fix a slow computer.
5. Scan for Malware and PUPs
Potentially Unwanted Programs (PUPs) often bundle themselves with free downloads. They are not always viruses, but they sit in the background and track your data, hogging your internet and CPU.
6. Check Disk Health
If your PC freezes for 30 seconds and then recovers, your drive might be failing. You can check this by typing cmd in search, right clicking it to run as Administrator, and typing chkdsk. If it finds errors, back up your data immediately.
7. Pause Windows Update Loops
Sometimes Windows gets stuck trying to install an update in the background. If you see a red icon in your taskbar or Update failed in settings, your PC is wasting 20 percent of its power trying to fix that loop.
8. Adjust Visual Effects
Windows has a lot of fancy animations and transparency effects. On older hardware, these cause lag. Search for "Adjust the appearance and performance of Windows" and select Adjust for best performance.
9. Reapply Thermal Paste
If your PC is 3 or more years old, the factory thermal paste on the processor has likely dried out. This leads to overheating, which forces the PC to slow down to prevent damage. Fresh paste is a cheap way to restore factory speeds.
10. Fresh Windows Reinstall
When all else fails, a Clean Install of Windows 11 is the nuclear option. It wipes away every piece of junk, every registry error, and every bit of malware. It makes the software side of your PC brand new.
Most speed issues are caused by software clutter or aging hardware. While these tips help, a professional deep clean and hardware check is the only way to ensure your PC stays fast for years to come. If you are in the Canning Vale area, drop me a message and let us get it sorted.
