MacBook back....

Been having some issues with the late 2008 MacBook recently. It had started to freeze up at odd times since installing Lion and refusing to wake from sleep. After various attempts to figure out the issue I took it into the Apple Store for a "genius" to check.
My 2GB of RAM was pretty much useless as the "genius" pointed out using Activity Monitor - just running a couple of YouTube videos dropped the spare memory down to around 20MB.
So, installed more RAM in the hope that would sort it out.

No use, still freezing, so back to the Genius Bar. Next diagnosis was a possible faulty hard drive connector cable and a overnight test bench session to see what was occurring.
News came back the other day that the hard drive was on it's way out.
I was tempted to install a 256GB SSD if the HD was the culprit, but in the end opted for a like for like replacement as the failed HD had lasted four years and if the new one lasts as long I'll be getting something a bit more modern by then.

So, having reinstalled everything from Time Machine I appear to be back up and running...
