Hi Deepak,
Welcome to digit forum ! I dont see any problem with ur OS or ur HDD in here, the problem is tht installation file of PowerDVD may be corrupt ! And thus ur facing such errors.
Dont try format ur HDD as often, coz this may make ur pc sick. So a good remedy for this is, just un-install the exisiting version of power DVD and install a newer version of power dvd and this might fix ur problems.
The newer version can be found @ companie's home page :
CyberLink :

PowerDVD v6.0 :

Download the Trial Version From:
http://download.gocyberlink.com/ftpd...VD_6_trial.exe
And install and check running ur files again and I hope you wont be getting any error messages in future.
And also updating ur OS will be a better idea !
