How can i check what cpu i have other then looking at the back of my pc monitor if its uncorrect?

The monitor has nothing to do with your CPU. The monitor displays stuff. If you're in windows, go to the run menu, and type in dxdiag. It'll load, and it'll show you what you have, and what speed.

Back of your PC monitor? Like your actually Monitor that displays the screen? How would that know what your CPU is? The main program people use is CPU-z http://www.cpuid.com/cpuz.php Its a program that reads all the info about your system information. You could just go into Device Manager and look it up there??? (it might not tell you the exact speed, but it well tell you the model).

cpu= central processor unit= the processor on the mainboard inside the pc. 230-240=230-240 Volts= the voltage of the power grid, you know , the wall socket. If you want to know your pc use this http://www.cpuid.com/pcwizard.php install and click on processor.

Depends which OS you're running. cat /proc/sys/cpuinfo will show you if you're running Linux.
