Here are the stats: Model Name: iMac Model Identifier: iMac5,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.16 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 4 MB Memory: 1 GB Bus Speed: 667 MHz The problem is my browsers are beachballin/pinwheeling frequently. They just lock up. Netflix seems to be freezing as well when I use video stream feature. This week I decided to defrag and also to use mackeeper. It's too soon to tell if the browser is going to freeze/lock on me. My questions are, 1) I bought this refurbished in 2007, is it time for a new one? 2) If it's not, what steps should I do to get away from these beachballing/pinwheeling browser locks? Currently I have 48 GB's free & I have 250 GB hard drive. No idea what happened in the last year or so. Everything has just been getting worse in turn of browser lock ups. One interesting thing is it's not crashing though when before it would crash if it couldn't handle something at a specific time. I have lots of music files but that won't effect my browser performance, right? I guess I could move over more files to an external drive. Just want to get this corrected this month. Just wondering what causes browser lock ups & the remedies for this. Does this sound familiar to anyone? I use Flock currently as my browser. But it happens with all the browsers eventually. Any suggestions would be helpful. Even if it means buy a new refurb'd IMAC and just save yourself the stress and time. If that's the case, what is the best way to avoid this browser lock up? Is it system performance speed that could be causing this? Thanks again for any suggestions to my current MACrisis Update: Right after I posted this and left to get some food, guess what happened? Beachball/Pinwheel screen freeze jubilee It isn't that bad right now but it gets progressively worse as the week rolls by.
