if it take a long to start your pc try this. http://netsquirrel.com/msconfig/msconfig_win7.html if it take a long time to shutdown try this. click start then type in white box regedit then find this "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management}, then change the value of ClearPageFile at Shutdown to a 0. A value of 1 will overwrite the file, which i would actually recommend for security. Also, you must also restart your computer" thank you "king64 " for this tip!!!
