try increasing your virtual memory through
System Properties => Advanced => Performance- Settings => Advanced => Change

and type appropriate value depends on your RAM Size.

What is your problem actually? Your CPU usage is always 100% or your CPU overheats?
If CPU usage is the problem, I guess it might be due to some nasty programs (viruses) running in the background. Win 7 doesn't ask questions like Vista!
If overheating is due to hardware, try to go to the BIOS and check the hardware monitor after using the machine for a couple of hours. If you can't go to the BIOS, try to get some free motherboard monitoring utility.
