Laptop slowing down with games or videos
I am using Dell N5010 laptop with Windows 7 running it.
It is all working fine as long as we do browsing or chatting in Skype, etc., But whenever I want to watch any video on YouTube or play in media player, or if I want to play games it is responding slowly and it doesn't seem to be able to handle any graphics. I have closed all background running applications to give more CPU for videos/games but no luck. I have added more RAM and still the same issue.
What is the Problem with this? Please help me out here. Thanks in advance!
