My computer started to overheat on a regular basis.
Even though Macs are notorious for running hot, this was something different. Processes would s l o w way down while the brain tried to keep the heart from exploding.
Or, while the software tried to prevent the hardware from melting. Take your pick.
I googled. And downloaded.
Lots of directions.
Took the plunge. Bought a new hard drive.
While I waited for that to arrive, jury rigged a laptop cooling device.
Then, like Christmas, the night finally arrived. Change the hard drive time. Note, three sets of directions.
Voila. I did it.
This morning, we're running 60 degrees cooler on the CPU.
How changing the hard drive accomplished that, I do not know.
I'm only slightly geeky.
