I have the usual problems with keeping my computer clean. I do all (if not most) of the preventative measures. However, I have noticed that my computer is still slow. I open the Task Manager and the processes show that System Idle Process CPU usage is high, I look on the Performance tab and see that the CPU Usage History is still low (under 50%) but the Page File Usage History is almost at 100%. I do not know what this is but could this be a major cause of the computer being slow?

Welcome to Bleeping Computer

We have a self-help thread for assistance with your problem. Please see Slow Computer?, Use this troubleshooting checklist.

System Idle process is used for measuring how much idle time the CPU is having at any particular time(100% minus the sum of all tasks CPU usage). It will display how much CPU Resources, as a percentage are 'idle' and available for use. One instance of this process operates per CPU, and runs to occupy the processor when other threads are not running. Normally this process should take up at least 90%+ of processor time on average (this is the value in the CPU column).

To understand what the memory usage fields represent, read "Performance fields overview".

It appears that something is hogging your pagefile - it could be an errant program or a virus.

I'd suggest checking the processes tab in Task Manager to see what's causing the excessive access (switch between the Performance tab and Processes tab)
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

How much physical memory do you have, and how much page file space? (To find out, go to Start -> Run and type in
. . . and read the information there.)
