Hi Adhiraj,
Here are a few tips to consider when running Scandisk and Defrag.
1. Restart to the Command Prompt and do a thorough Scandisk on the
drive first and repair any errors.
Restart the computer. Hold down the CTRL key while the system is
booting. This will take you to the Boot Menu then select Command
Prompt Only. Run Scandisk on the drive from there by typing SCANDISK
then press enter and let it perform a surface scan.
2. Close all running programs using Close Programs (Ctrl + Alt + Del)
except Explorer.
3. Turn off screen savers and any power management
4. Delete Temp files and Temporary Internet Files
5. Empty the Recycle Bin
6. Do a virus scan with up to date virus software

9. Run Ad-aware to remove any possible spyware
