As you appear to have been abandoned I'll step in.
You have an awful lot of processes running.
I suggest that you go to start, click run, and type msconfig, then hit enter.
Now go to Startup, and check through the list of programs there.
Any that you don't know if you need, either search Google or ask here. Do not disable any security programs.
Uncheck unneeded programs and reboot when asked. That should free up some resources.
