An ever increasing number of tools on my computer has left me with a computer than sometimes, maybe 10-20% of the time, uses 100% of the CPU and twice as many MB of RAM as it actually has, forcing me to use the hard disk as virtual memory. In addition to this I have used almost 60% of my hard disk in the year and a half I have had this computer. I am contemplating upgrading to 1GB RAM and maybe getting an external hard disk. But recently I increased the maximum size of the paging file to 800 MB and a minimum of 400 MB. I have noticed an increase in performance since then. Could I just get away with having a huge paging file? How big can I make it? is it really worth it to ad to the computers motherboard? Should I just stop running so many start up programms?
