LAPTOP GETTING SLOWER AND SLOWER

[Phil TK]

I'm surprised nobody has suggsted looking at the processes in task manager, this will actually tell you what is taking up cpu power. I should mention that you should never delete a process in TM, the trick is to google the names of any busy processes and you'll invariably find a geeks forum telling you what it is and how to deal with it -if it's an erroneous process.
I have a utitlity on my laptop which shows cpu % usage, temperature and fan speed on the taskbar, it's dead handy for monitoring the computers performance.
