Macbook increasingly hot and slow
I have a May 2007 Macbook C2D 2.0Ghz 1Gb RAM 250Gb HDD (183Gb free) running 10.6.8.
When I bought this computer I was able to open 10 apps at once without it slowing to a grinding halt, today even just using Chrome is slow. 99% of the usage is just surfing the web, but increasingly the machine is struggling with this task.
2-months ago the machine had a rebuild that helped, but now its worse than ever. Apple have used a diagnostic tool on the hard drive and found no issues. I have used a McAfee virus scanner and no threats are detected.
Understand that this machine now has a few years behind it, but I am not asking anything from it that I haven't been over the last 5 years. If I didn't know better I would suggest that it feels like the CPU's performance is degrading causing it to run at max continuously. This is then creating a lot of heat and leading to a vicious cycle. I will get a usage monitoring app and update this thread with my findings in a few days.
More RAM would obviously help, but I have been fine over the last few years. Any suggests would be appreciated.
