I would like to know with several applications running, how much free RAM does my computer have. How I can monitor the temperature and fan speeds of my system and processor fans? Also, I want to know how I can obtain a detailed report on the hardware configuration of my computer.

There are various applications you can use to monitor the state of your system at any given time. One of them is a www.coolmon.org program called
CoolMon where you can monitor about 22 of the most geekiest system parameters like the temperature and speed of your system fans, the number of processes running, the total available memory on your hard disk and RAM, CPU utilization, etc. Each of these can be individually configured to appear on the interface.

Best of all, this monitoring happens in real time. Better still, the program is free.If you need more details than what is offered by Windows System Information or the Device Manager, try out an application called Everest Home Edition (www.lavalys.com). This application hunts through your hardware and software setup and extracts every piece of information you might need about your processor, motherboard, graphics card, hard disk and any other piece of hardware or software information that you might care to know about your computer.
