Programs freezing/slow after Mountation lion installation.
I upgraded to mountain yesterday on my iMac, which is about 2 years old. Since then, the computer has beein running like a dinosaur. MS Word freezes and lags each time I open it. MS Outlook is slow. I can't do more than one thing at a time, or the spinning circle appears. I'm rebooted a dozen times. I tried holding command+option+p+r but that won't work.
The phone tech said I need to take the computer into a shop. Please tell me there is another way to deal with this? My computer was perfect before Mountain lion and now it runs like an old computer. Also, I can hear the hard drive chugging away in the background constantly like its working very hard.
OS X Mountain Lion (10.8.2)
