Since my last PC died I have been trying to keep my new PC clean and healthy.

Every week I have been doing the following things. Defragging, full anti virus scan and CCleaner (to delete unused registers).

Is there anything else I should be doing to keep my PC running faster?

Do I need to clean my hard drive before I install new leapord? How do I clean hard drive.

Clean computer?

how can you keep your laptop screen clean and stop collecting dust, i even always wash it!!! ahh.. i never touch it either.

I was scanning the computer and it said that there were something deep in the system the I should look for this.
