What not to spare in this case refers to properly maintaining your computer system Thus performing regular system maintenance. A clean PC is a happy PC. Yep, you read it right here. And I did say that. If you want to have your PC running properly, you need to keep it clean and do other periodic procedures such as running DEFRAG to de-fragment your hard drive. This means you are taking files that are splintered throughout your hard drive and reorganize them so all the splinters are gone and more space is freed up. If you start now to keep your PC properly maintained, then you will develop consistent habits regarding the care of your PC so that it stays well kept throughout it’s life.
