Most of the times its hard to get all the technical details of the hardware in the computer unless you are a pro. So if you are not a professional and wondering what you got in your computer and might be interested in looking all those details, here are some free software which will help you achieve that. Going through all those details will surly help you to build some knowledge on the hardware details. Or if you are working as a professional computer hardware guy, then rather than getting pieces of information here and there, you may use this software as a one stop portal to get all the information of all the hardware details.

The best advantage of this software is that you need not install this in your computer nor it requires any change in the registry. Just download the files and run the .exe file

PC Wizard
PC Wizard is from the same provider as CPUZ and they give very extensive report on all the hardware details of the computer. They detect all kinds of hardware attached to the computer and give the analysis report. They also give reports of benchmark details such as CPU performance, Cache performance, RAM performance, Hard Disk performance, CD/DVD-ROM performance, Removable/FLASH Media performance, Video performance, MP3 compression performance.

They give details in sections like Hardware, Configuration, System Files, Resources and Benchmark.
Here is the list of some of the general most wanted technical information of the hardware analyzed by PC Wizard.
