What is constantly using my ram up?

I have a Clevo 870 and have the google desk top it tells me CPU usage and other stuff it says that something is using 20% of my RAM and it seems to go up every day two days ago it was just 16%. There is nothing running that I can see? When I first used the google desktop it would say 0% when at idle what is using my ram any IDEAS or how I can find out? Thanks any help would be nice..
OH nothing is showing in the task manager also..

 

punctuation man....
Anyway, RAM is random and you can't hope it to stay an a constant level. Unless that 4% difference means 100MB, I can't really say something is wrong with it.

And you said nothing is showing in task manager?

 

It's impossible for your ram usage to be 0, or even less than 10% for Windows 7. Windows has functions that load things into RAM to improve performance. Memory being used is not a bad thing, that's why it's there.

 

Mostly page files from your background application
download process explorer to find out who's the culprit. Restart the application, that might reduce some memory usage.

 

It would be a problem if there weren't any free memory, but since there plenty more to be consumed all is ok. That's why we have 4gb or more, to be used up and to still have some spare for something you, instead of the OS, need.

 

Windows 7 does a lots of caching in the RAM in order to speed up the system. What is the point of having 4GB of RAM is you use only 10 % always (This was a 98 and XP thing). Linux does the same. The important thing is that how fast is the RAM freed when another application needs more RAM.

 

OK thanks for all the info I guess everything is ok. I would swear I remember seeing it at 0%. Thanks for the help guys. Also, I love this Clevo 870 it is way better than man dang Alienware M17x R2. NO little grimlins in this machine..

 

There's a good chance the software is reading incorrectly. You can check with the task manager, that will always give you the correct numbers.
