How much RAM does it have?
When was the last time you used a can of air to clean out the vents?
Does this only happen with Browsers?
I am using a Macbook Pro. With 10.7.5 OS.
6 months ago my mac has gone through stages of freezing when I open Chrome. It starts on the navigator but eventually spreads to anything in use in the the Mac creating a freeze of the whole system (iPlayer desktop, finder, PS, iTunes)
I first started by uninstalling Chrome and using Safari instead. This worked for a couple of months. Then the same thing happened to Safari. So I moved to Firefox a few weeks ago but I'm afraid the same thing will eventually happen to Firefox so I am asking for help before it happens.
I have made numerous steps to counteract this such as Verifying and repairing disc permissions, downloading latest Flash.
Many thanks for any help anyone can give me.
