I have been experiencing a serious performance problem on my PC for over a year now. I only use the PC for light work and yet sometimes if I click from one email to another in outlook I will get about 30 seconds of HDD activity before it opens the next email. I get the same if I try and open firefox.
I just tried to go into System properties>Advanced>under visual effects selected best performance. I do this a lot for third party machines and it takes 15-20 seconds to take effect. My PC waited over 2 minutes.. I just cant figure out what it is. Its like ther is some disc cache that has no purpose. This is a 3.6GHz P4 with 2G of Ram. I look in task manager when it is thrashing and CPU idle is 99%. Are there any system tools that can tell me what this machine is doing?
