From a short amount of time my PC started giving problems like:
When i try to put it in sleep mode the screen turns off but the pc continues to run
Sometimes when I try to do the Restart/Log off it gets stuck on the "Logging Off" screen
sometimes while playing games or watching movies and then i use the Alt+Tab function it "freezes" like i am still able to move the mouse but all the apps stop responding
in that case even Ctrl+Alt+Del-->Task manager wont work
I have uninstalled some program that i tough may be the problem but it didn't helped
I am having a paid version of "Norton Internet Security " which catches the viruses that it sees but could it missed a virus?
i do a deep scan every month and it find about 1 to 2 viruses every time but even after that the problem is the same

Please give me advice
Thanks
