Why Does My Computer Take Forever to Start Up?
You press the power button, the logo appears… and you wait. Then the desktop shows up, but you still can't do anything for another minute. Slow startup has a handful of common causes, and most are easy to fix.
Two kinds of "slow boot"
It helps to separate:
1. Slow to reach the login screen: usually hardware, firmware or a storage problem.
2. Slow after logging in: usually too many startup apps loading at once.
2. Slow after logging in: usually too many startup apps loading at once.
Most people suffer from the second kind.
Fix 1: Trim your startup apps
Every app that launches at login competes for your drive and processor.
• Windows: Open Task Manager (Ctrl + Shift + Esc) → Startup apps. The "Startup impact" column shows the worst offenders. Right-click → Disable.
• Mac: System Settings → General → Login Items. Remove anything you don't need immediately.
• Mac: System Settings → General → Login Items. Remove anything you don't need immediately.
You can still open these apps whenever you want. They just won't launch automatically.
Fix 2: Upgrade to an SSD
If your computer still uses a traditional spinning hard drive, this is the biggest single improvement you can make. Machines that take a couple of minutes to boot from an HDD often start in well under a minute from an SSD. Cloning tools make the move possible without reinstalling everything.
Not sure what you have? On Windows, open Task Manager → Performance → Disk, which shows "SSD" or "HDD".
Fix 3: Check Windows Fast Startup
Fast Startup saves part of the system state when you shut down so the next boot is quicker. It's usually on by default. To check: Control Panel → Power Options → Choose what the power buttons do.
Note: if you're troubleshooting problems, turning Fast Startup off can help, because it means a shutdown fully resets the system.
Fix 4: Install pending updates
A boot that hangs on "Working on updates" is often an update that needs finishing. Let it complete, then restart again. Repeated update loops are covered in our update-problems guide.
Fix 5: Scan for malware
Malware often installs itself to run at startup. A full scan with Windows Security or another reputable tool is worth doing if boot time suddenly got worse.
Fix 6: Free up disk space
A nearly full drive slows everything, including startup. Keep at least 10–15% free.
Fix 7: Check external devices
USB drives, docks and some peripherals can delay startup while the system checks them. Try booting with everything unplugged except keyboard and mouse.
Fix 8: Update firmware (BIOS/UEFI)
Your PC maker may release firmware updates that improve boot behavior. Use their official support tool or website, and follow the instructions carefully. Don't interrupt a firmware update.
Should you just use sleep instead?
For many people, putting the computer to sleep rather than shutting down is the practical answer. It resumes in seconds. Just restart once in a while so updates install and memory is cleared.
The bottom line
The biggest wins are disabling unnecessary startup apps and moving to an SSD. Do those two things and most computers go from painfully slow to ready-when-you-are.
