ASUS P9X79 Deluxe, X79
Core i7-3930K, 6x 3.20GHz

Windows 7 Professional
After installing OS the C drive (60GB SSD) shows full. I've check the size of each windows folders, in total it shouldn't be more the 10-12GB. I've tried to clean the disk, no luck. Some of the people says it's because of the huge RAM installed. Could any one help me. Thanks
Check the root folder of the C: drive to see how large your pagefile and hibernation file are. The pagefile tends to get created quite large if you have a lot of RAM (ironic, since generally speaking the more RAM you have the less pagefile you need).
If you allow hibernate, which I think is the default, you will need a drive space equal to the size of ram. But, it is not so easy to get rid of it if you have ever used it. Google the issue if you think that might be the cause.
To make hibernation unavailable, follow these steps:
1) Click Start, and then type cmd in the Start Search box.
2) In the search results list, right-click Command Prompt, and then click Run as Administrator.
3) When you are prompted by User Account Control, click Continue.
4) At the command prompt, type powercfg.exe /hibernate off, and then press ENTER.
5) Type exit and then press ENTER to close the Command Prompt window.
Check on the root of your C: to see if Hiberfil.sys (hidden, system file) is gone. If not delete it.
I guess you know that when you hibernate a machine in Windows it takes a snapshot of what is currently in ram and saves it to the Hiberfil.sys file. With your colossal amount of ram and speedy SSDs I see no point in ever hibernating your machine. You would save a couple of seconds at most. That's a beast you have their.
You can also move your pagefile to your raided SSDs and reduce their size to ohh say 1gb. Can't say Windows would ever need to use it when you have 64gb ram. There is much debate to be found about whether to disable it entirely something you could check out if you feel the need to save some more.
Don't forget Windows restore also likes to steal a few gigs. Once fully up and running you can delete all the restore points prior and create a new one.
Also check out your C:\Users\you\AppData\Local\Temp (hidden) directory. You can delete all (you're able) from here. Usually loads of dross left over from installs / setups etc.
Then finally run a system cleaner like CCleaner or Auslogic Registry Cleaner.
