Laptop Running Slow Laptops performance # Laptop Running Slow ## Quick Answer A slow laptop is usually caused by too many startup programs, low storage, insufficient RAM, or malware. Please note: This guide is provided for informational purposes only. Any steps you choose to follow are at your own discretion and risk.

Restart the laptop A fresh restart clears memory and stops background processes. 2. Check startup programs Disable unnecessary startup programs in Task Manager. 3. Free up disk space Ensure at least 15-20% of your drive is free. 4. Check for malware Run a full scan with your antivirus software. 5. Check Task Manager Look for processes using high CPU or memory. ## Guided Troubleshooting Answer these questions to narrow down the issue. Is the laptop slow only at startup? YesNo Has it been slow gradually or suddenly? YesNo ## Possible Causes Too many startup programs Very Common Programs launching at startup slow boot time. Low disk space Very Common Less than 15% free space degrades performance. Insufficient RAM Common Too many apps open for available memory. Malware Moderate Malicious software consuming resources. Failing hard drive Moderate A dying HDD causes extreme slowdowns. SSDs are much faster. If the cause requires professional attention, see [Laptop slow performance repair](/repair/laptop/slow-performance). ## Self-Fix Instructions Safe steps you can try at home. 1. ### Speed up your laptop 1\. Open Task Manager > Startup tab. 2. Disable non-essential startup programs. 3. Uninstall unused applications. 4. Empty the Recycle Bin. 5. Run Disk Cleanup. 6. Consider upgrading to an SSD if you have an HDD. ## Safety Warnings - Be cautious with 'PC cleaner' software — many are scams or contain malware. ## When troubleshooting isn't enough If these steps didn't resolve the issue, a professional diagnosis can identify the root cause.
