Can't extract some rar files with my laptop dvd drive.

[bloodwheel]

I have a dell xps 14 ,core i7 740qm,window 7 64bit home premium,4gb ram,500 hdd 7200rpm and dvd burner.Since the day i bought that laptop i can't extract some rar files.I have tried copying it to my hard disk and even tried make an image copy and open it in virtual drive but still no luck,it keep showing me that window don;t know how to open it.Other desktop pc DVDdrive can extract it easily.I have installed 7zip and WINRAR.But the extraction isn't happening.Since then when ever i want to extract a zipfile (which i can't extract on my laptop)i have to borrow a friend pc to extract it.Any suggestion would be nice.

The particular files may be corrupted or 7zip/winrar may be corrupted. Check.

Maybe the software you downloaded is a 32bit version? Have you tried going to start > programs > and running manually 7zip or WinRar as administrator? (i.e. not using the right click drop-down menu shell extension on a zip)
