How do i find out the TOTAL memory size contained by my computer?

right click on my computer and goe to properties, on the first tab it will let somebody know you under a box called my computer: how much push you have, you can in recent times right click on the drive letter C: and do properties to find out how much memory you enjoy on the hard disc, and it will report you free space.
Start>My Computer>Right Click C Drive> Properties.
Well, first it depends on what kind of computer you own. Like imac? dell, what? but I would try something like system preferences, umm... I know exactly how to find that out on a mac, but you can telephone like circuit city :)
Press the window key (between the Ctrl and the Alt key on the lower left side of the keyboard) at matching time you press the Pause/Break key. This will show you the System properties skylight. Toward the bottom of this screen it will report you haw much RAM your computer has.
Press CTRL + ALT + DEL .

When Windows Task Manager pops up.

Click on Performance Tab.

You will see how much memory you own

and how much memory is being used.
