Ken's right.
Having 53 processes running is not unusual, expecially if you have antivrus
and anti-spyware starting up whenever you logon.
My processor usage stays at about 7-10% unless I'm really doing some serious
file swapping or number crunching.
I currently have 51 processes running (including Norton AV, Ghost, and some
antispyware) and my CPU usage is only at 9%. The slowness might be due to a
lot of pagefile swapping due to a low amount of RAM. If you don't have more
than 256 MB of RAM (that's all most machines come with from the factory...),
then you might consider bumping it up to at least 512 MB. If you go to 1 GB
of RAM, you will have a pretty big cushion for multitasking and a noticeable
increase in performance. I have 2 GB in mine...
Browse through your startup and take a look-sy at everything that starts up
when you logon. A lot of downloaded stuff starts up by default when you
install it (Yahoo messenger, MSN Messenger, etc.). I f you don't need these
programs until you are ready to use them, then remove them from the startup
configuration. You can get there by using the Start>Run>mconfig and click on
the Startup tab and browse through there to look at the programs that run on
every startup.
If there's a couple of them that you don't need, then un-check them, click
"apply", click "OK", and then reboot.
This will also allow your machine to boot a little faster.
Hope this helps.
