PC hangs while inserting Cruzer Blade 8GB

please suggest any solution

Check AV and/or other anti-malware apps for checking all the files before allowing access to the drive.  Also check if Windows is indexing the files on the drive.  And check if an app on the drive is phoning home looking for updates when activated.

See if this thread helps:
