7 Costly Tech Mistakes You’re Probably Making (And How to Fix Them)
In the world of IT, what you don't know can cost you hundreds of pounds in repairs and lost data. Whether you're running a business in Wickford or managing a high-end gaming rig, common habits often lead to premature hardware failure and security risks.
As we move through 2026, tech is faster than ever, but it’s also more sensitive. Here are the seven most common mistakes the team at LaunchLayer sees every week—and how you can avoid them.
1. Ignoring "End-of-Life" Software
Many users are still clinging to older operating systems like Windows 10. In 2026, using unsupported software is like leaving your front door unlocked. Without security patches, your system is "low-hanging fruit" for modern ransomware.
The Fix: If your hardware doesn't support the latest OS, it might be time for a professional upgrade to ensure you stay protected.
2. Using "Compressed Air" the Wrong Way
We all know dust is the enemy, but blowing a can of compressed air into a laptop without holding the fans still can actually generate electricity that fries the motherboard.
The Fix: Always use short bursts and never let the fans "over-spin." Better yet, book a Professional Internal Clean at LaunchLayer to have your system safely stripped and de-dusted.
3. Waiting for the "Blue Screen" to Act
Most people only call an IT expert when their computer won't turn on. By then, the damage (like a failing SSD or a burnt-out GPU) is often permanent.
The Fix: Watch for the early warning signs: unusual fan noise, "stuttering" during video calls, or long boot times. Early intervention usually costs 70% less than a total emergency repair.
4. Neglecting Your Thermal Paste
Thermal paste is the "oil" of your computer’s engine. After 2–3 years, it dries out and becomes a thermal insulator instead of a conductor. This leads to thermal throttling, where your expensive processor slows down just to stay alive.
The Fix: We recommend a "re-paste" every 24 months to keep your temperatures low and your speeds high.
5. Buying "Cheap" Power Supplies
For custom PC builders, the Power Supply Unit (PSU) is often where they try to save money. A low-quality PSU doesn't just fail; it can take your motherboard, CPU, and Graphics Card down with it.
The Fix: Always look for an "80 Plus Gold" rating or higher. If you’re unsure, ask us to review your parts list before you buy!
6. Relying on a Single Backup
Think your files are safe because they're on a USB stick or "in the cloud"? Think again. Syncing a virus-infected file to the cloud just means you now have a virus in two places.
The Fix: Follow the 3-2-1 Rule. Three copies of your data, on two different types of media, with one copy stored physically off-site.
7. DIY "Vibe-Coding" and Unverified Apps
With the rise of AI-generated apps, many users are installing unverified software that hasn't been audited for security. These "quick fix" tools often come with hidden "ghost infrastructure" that monitors your keystrokes.
The Fix: Only download software from trusted sources and keep a modern, active firewall running at all times.
