Should I wipe my computer or just delete all the rubbish on use the disk defragmenter?
First do a disk cleanup. Right click the drive in My Computer, choose Properties and Disk cleanup. Delete the temp files, temporary internet files, empty the recycle bin etc. Don’t compress the drive contents. Then you can defrag. I never liked the in-built Windows defragger; instead I use Diskeeper. Head over to http://www.diskeeper.com and download the free trial version of Diskeeper 2009. It’s the best defragger for Windows and defrags everything including large files and system files, even with low free space. Install Diskeeper, turn on the auto defrag mode and dont worry about defrag again! Diskeeper will do everything in the background automatically, and you can use your computer as usual.
