Windows 7: my computer freezes with i am copying some files from DVD to HD

my system is

ram: 8G

cpu: i3



system: windows 7

the files are small like 500mb

but the whole computer freezes when i m copying it to my harddrive


it's just too laggy that i couldnt even perform ctrl + alt + del.


is there anyone know what the problem is?

What type of hard Drive is it? Single HD or multiple HDs?

It may just be the drive is really busy or the CD/DVD drive is having issues reading the disc causing some hangs.

Does everything return to normal after the copy? Also, is just that particular disc or from any disc.

it happened on several different DVDs.

things were back to normal after copying.

while copying, there are not many programs going.


and i tried that DVD on another computer with windows xp as OS. it worked perfectly fine.
