You must have a slow processor, or your hard drive has problems. You can check the hard drive with the Health tab on Defraggler. Don't go by Defraggler's Health status, look at the numbers. Numbers in the millions or more for Spin up time or Command timeout indicate problems. Also anything greater than zero for Seek Error Rate, Reported Uncorrectable Errors, Current Pending Sector Count, Uncorrectable Sector Count or UltraDMA CRC Error Count are all indicators of a failing drive.
