PC Maintenance Myths – What You Should and Shouldn’t Worry About

Everyone Has an Opinion

You’ve probably heard it all:

  • “Leave your PC on all the time—it’s better for it.”
  • “Don’t touch the inside or you’ll break something.”
  • “You must defrag your drive every week.”
  • “Macs don’t need maintenance.”
  • “Dust doesn’t matter—it’s just cosmetic.”

The truth is, PC maintenance is important, but a lot of what people believe is outdated or just plain wrong.

Let’s bust some common myths and help you focus on what really keeps your system running smoothly.


Myth #1: “You Don’t Need to Clean the Inside of Your PC”

Reality: You absolutely do.

Dust is the silent killer of computers. It clogs fans, traps heat, and causes components to overheat — which can lead to system crashes, slow performance, and even hardware failure.

At Big Bang PCs, we regularly clean out:

  • Fans
  • Heatsinks
  • Power supplies
  • GPU shrouds
  • Case filters and vents

How often? At least once a year. If you live in a dusty area (or have pets), every 6 months is even better.


Myth #2: “Defrag Your SSD for Better Speed”

Reality: Defragmenting SSDs is not only useless — it’s harmful.

Defragging was essential in the days of mechanical hard drives. But SSDs work differently. Defragging them:

  • Wastes write cycles
  • Doesn’t improve speed
  • Shortens the lifespan of your drive

Instead, let Windows 10/11 handle SSD optimization automatically.


Myth #3: “You Should Leave Your PC On 24/7”

Reality: There’s no one-size-fits-all answer.

Leaving your PC on all the time can:

  • Be convenient for remote access or updates
  • Reduce thermal stress from frequent booting

But it also:

  • Consumes more electricity
  • Attracts more dust due to constant airflow
  • Shortens the life of fans and moving parts

Tip: Shut it down if you’re not using it for 8+ hours. Or use Sleep mode if you want a balance.


Myth #4: “Macs Don’t Need Maintenance”

Reality: All electronics need care — Macs included.

While macOS handles some things in the background, you still need to:

  • Keep software updated
  • Check for overheating and dust
  • Monitor drive health
  • Clean ports and vents
  • Backup regularly

Macs get dusty too. We’ve opened up iMacs filled with clumps of dust — sometimes worse than gaming PCs.


Myth #5: “Antivirus Is All You Need”

Reality: Antivirus is part of your defense — not your entire defense.

In 2025, cyber threats go beyond viruses:

  • Ransomware
  • Phishing
  • Cryptojacking
  • Malicious browser extensions

Antivirus helps, but user behavior matters more:

  • Don’t click unknown links
  • Keep software up to date
  • Use a password manager
  • Turn on 2FA where possible

Windows Defender + good habits = solid protection for most users.


Myth #6: “You Need to Reinstall Windows Every Few Months”

Reality: That used to be true… in 2005.

Modern Windows versions are far more stable. Unless your PC is infected or corrupted, there’s no need to reinstall Windows regularly.

Instead:

  • Clean your startup apps
  • Keep drivers updated
  • Delete junk files occasionally
  • Let Windows handle updates and security patches

Pro Tip: We offer a Software tuneup service to make sure its all ship shape.


What You Should Do: Simple Maintenance That Works

Here’s a quick maintenance checklist we recommend at Big Bang PCs:

Every 3–6 months:

  • Get it serviced and tuned up.
  • Wipe down keyboard, screen, and case
  • Check for bloated startup programs

Once a year:

  • Bring your machine in for a service so we can attend to these frequently:
  • Check thermal paste (especially on gaming PCs)
  • Clean out GPU fans and PSU
  • Run drive health checks
  • Backup important data

Always:

  • Keep Windows and drivers updated
  • Be careful online
  • Use surge protection
