BTW here's my spec

AMD Athlon II , X3, 3,0 GHZ

DO i have to format and re-install my windows
my sfc result

Lol 1. If you reboot once and the problem's not fixed, don't reboot again. That just messed up your computer.
2. Try upgrading to a 64-bit? I did upgrade to that about 3 days ago and everything works so smoothly. xP

In the SFC output it shows that it found issues but could not fix some of them. That sounds like your problem right there. A Repair Install is most likely necessary here. And, don't download any more optimization tools. Windows 7 does very well without them.

Okay, if you are using the program Advanced System Care 5, you may have set the iobit smart ram to clear the clipboard. So as often as you copy something, it clears it out. Hope that helps some of you. Just change the settings to not clear the clip board.
