Programs install slow, system almost unusable when transferring files

[safetybar]

Hello-

Has anyone run across this? Whenever I install a program via the DVD drive or from a mounted ISO the install is painfully slow. The system them responds super slow. This also happens when transferring files from multiple drives. I understand there will be a lag when the hard drive is in use, but this never happened under the same setup in Vista.

Have you updated all your drivers? Mine seems fine.

Yeah everything is fully updated. I cant quite figure this one out.
