The Alien Tech CPU is a simple Windows gadget that lets you monitor the load of your CPU and memory. With it you’ll be able to see if your computer is working at its best and it will show if there is something wrong with it. Once you see if there is a problem you can then plan your next step. Another cool perk of this gadget is that it is available in three colors namely red, blue, and green. So if you are tired with one color you can immediately change it to suit your preferences.
