Fix Slow Computers: Windows 11 & 10

Understanding the Sudden Slowdown

It can be frustrating when your once-speedy computer becomes painfully slow overnight. As technicians at YourPCRepair.co.uk, we've seen this scenario unfold countless times. Fortunately, most causes of a sudden slowdown in Windows 11 or 10 are fixable with some straightforward steps.

Common Causes and Solutions

1. Overloaded Startup Programs

If your PC is slow on startup, too many programs might be set to launch when you boot up. This not only delays the startup process but can also keep your system running sluggishly.

• Press Ctrl + Shift + Esc to open Task Manager.

• Navigate to the Startup tab.

• Disable non-essential programs by right-clicking and selecting Disable.

2. Insufficient RAM or Storage

Inadequate RAM or a nearly full hard drive can severely impact performance. Consider upgrading your hardware if your computer is still laggy after clearing unnecessary files.

• Free up disk space: Use the built-in Disk Cleanup tool.

• Upgrade RAM: If your system supports it, adding more RAM can boost performance significantly.
