Hi Babita,
Thanks for your reply....
But solution did not work for my problem...
Whatever I am typing right now is from external keyboard only.. Typing working correctly on external keyborard but getting wrong characters mentioned in above forum when I type with my Laptop keys....
as per your suggestion I run ePSA Diagnostics also and it ran completely and successfully with no detection of errors.
But problem is still not resolved.
I tried running in Safe Mode but On pressing 'F8' during boot up, Safe mode is not appearing.
I am using Windows 8....
Please provide me solution soon.
