clear your page file at shutdown

A page file is just like a ram present in harddisk.This contains your data,when it is not required by your cpu.
u can clear this page file when your system shutdowns

just open the notepad and type the following code and save it as clearpage.reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
"ClearPageFileAtShutdown"=dword:00000001

[HKEY_USERS\.DEFAULT\Control Panel\Desktop]
"AutoEndTasks"="1"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control]
"WaitToKillServiceTimeout"="10"



After its saved.open the file and say "yes","ok"
Now every time your windows shutdown,your page files get cleaned up
