If you’ve used PCs for years or haven’t used some of the older versions of Windows, you might appreciate The Restart Page—a site that displays the restart sequence for many of the older operating systems including Windows 1.1, 2000, XP, NeXT, and Apple operating systems.

You probably have a hard drive in your home that’s one terabyte or more. If you open Computer (Windows Key + E), you’ll see your terabyte hard drive might only show a capacity of around 930 GB. Where did all those extra gigabytes go? Aren’t there a thousand gigabytes in a terabyte? If you have questions like these, this guide answers them.
Terabyte vs. Tebibyte
Hard drive manufacturers use the International System of Units (SI) convention to when listing hard drive capacity. Kilo-, mega-, giga-, and tera- are some of the prefixes used in accordance with the SI and are base-10 (decimal.) “Tera” means trillion so a terabyte is one trillion, 1,000,000,000,000, or 1012 bytes.
Over time, dust and dirt build up inside your laptop; thereby, restricting airflow, increasing heat, and putting a strain on your laptop’s fans. A hot laptop is not a happy laptop. In fact, most modern processors (CPUs) reduce their clock speed when temperatures get close to 80C (think of it as a “survival mode” for your CPU), which is generally accepted as the highest temperature you should let your CPU reach. The dirtier the airways in your laptop, the quicker your CPU’s temperature can jump to dangerous levels—especially when the airways are further restricted by a pillow, your jeans etc.
To help stop your laptop overheating, consider clearing the channels by which air is designed to flow through your hardware. This guide provides a few tips to help you keep your laptop’s airways free of dust and dirt.
If you’re using an older computer or a computer that came without a dedicated graphics card (GPU – Graphics processing unit), you may have considered getting a more powerful GPU. An upgraded GPU will let you:
- Play games at higher resolution, detail, and frame rate
- Play HD video without stutter
- Use two or more monitors (helpful if you can only use one with your current setup)
- Speed up photo and video editing
In this guide, I’ll show you the basics of finding out what your upgrade options are and how to install a new graphics card.
The computers I work on every day are cooled by an on-board water cooled heat exchanger—without water cooling (WC), they’d either run slowly (best case) or overheat and shut down (worst case.) Outside the enterprise, liquid cooling isn’t as necessary but, for around $100 US, you too can enjoy liquid cooling technology on your overclocked home rig. In this guide, we’ll cover the basics on liquid cooling and explain why liquid cooling is superior to air cooling. We’ll then look into why you really don’t need liquid cooling for your home PC—but don’t let that stop you!
