|Try defragmenting all visible partitions on the hard drive:|
Start > All Programs > Accessories > System Tools > Disk Defragmenter
Don't use your laptop while it's defragmenting data otherwise it may keep restarting from the beginning.
Another reason for the system becoming slower is that the hard drive may be getting full so the free space gets too low. You need to think about removing some data or some applications you don't use.
Or install a larger capacity hard drive.
