hi guys. well from few days i am experiencing these problems. 1.sometimes when i restart the system through windows.it just goes to kinda 'stand by mode'.i mean even if i move the mouse or press any button it does not show any response and remain in that condition only until i restart by pressing the restart button. 2.some games which used to work better earlier now slows down sometimes or even stutter unecessarily sometimes. 3.to open 'my computer' or 'my documents' by double clicking through desktop takes a noticeable amount of time.it takes more time to open.
