Recently my old mbp has been very lagging when I tried to login at any websites. (e.g. email or forums) This happens started usually when the machine running a certain amount of times. When I tried to restart the computer, it would take more than 30 minutes to get a restart and sometimes it would just stuck at the spinning icon white page with an Apple logo and I had to hard shutdown a couple times. 
I notice this situation occurs after Mountain Lion released. (This machine is still running Lion, but have couple apps updates like Safari etc. since the ML releases)
Can any experience users help me out about this issue? Thanks in advance.
