The computer has a 144GB capacity, 76.35GB free space (52%). I cannot complete a disk cleanup. I tried doing a defrag at 2A this morning and at 8A it was only at 32% complete. Where do I start and how do I find out what is using the memory? I use a DSL line, but the computer is performing as if it were a dialup. Also, my hobby is photography…a lot of pixs. This is a Dell..so forget Customer Service.
