Step 1: Repair Corrupt System Files (SFC)

If your Windows is acting weird or crashing, use the System File Checker:

• Open Command Prompt (CMD) as Administrator.
• Type sfc /scannow and hit Enter.
• Windows will automatically scan and fix any broken core files.

Step 2: Fix Disk Errors (CHKDSK)

Slow file opening? Your hard drive might have logical errors:

• In CMD (Admin), type chkdsk /f /r and hit Enter.
• Type Y to schedule the scan for the next restart.
• This tool repairs drive sectors and improves speed.

Step 3: Check RAM Health (Memory Diagnostic)

If you get the Blue Screen of Death (BSOD), your RAM might be the problem:

• Press Windows + R, type mdsched.exe and hit Enter.
• Choose "Restart now and check for problems".
• The PC will reboot into a blue diagnostic screen to test your RAM sticks.

Step 4: Clean Boot Troubleshooting

To find out which app is causing lag without third-party software:

• Press Windows + R, type msconfig and hit Enter.
• Go to the Services tab, check "Hide all Microsoft services", then click Disable all.
• Restart your PC to see if the lag is gone!
