Step-by-Step Solutions to Fix Laptop Blue Screen Error
STEP 1: Restart Your Laptop (Basic Check)
Sometimes BSOD happens due to a temporary glitch.
✔ Restart your laptop
✔ Remove external devices (USB, printer, external HDD)
✔ Check if the issue repeats
If BSOD continues, proceed to the next steps.
STEP 2: Note the Stop Code
When BSOD appears, carefully note:

If BSOD started after updating a driver:
Open Device Manager
Right-click the suspected device
Click Properties
Go to Driver tab
Select Roll Back Driver
Restart the laptop.
STEP 6: Run Windows Memory Diagnostic (RAM Check)
Faulty RAM causes frequent BSOD.
Steps:
Press Windows + R
Type: mdsched.exe
Click Restart now and check for problems
Windows will test memory and report errors.

STEP 7: Check Hard Disk / SSD Health
Bad sectors or failing drives cause crashes.
Run CHKDSK Command
Open Command Prompt (Admin)
Type:
chkdsk C: /f /r
Press Y and restart
This scans and repairs disk errors.
STEP 8: Repair Windows System Files (SFC & DISM)
Corrupted system files cause BSOD.
Run SFC Scan
sfc /scannow
