svchost and lsass are background processes vital to the running of Windows. Which is why it wont let you kill them

Your best bet for lowering the amount of resources they use is to disable any Services you dont use, and make sure any software you aren't using isn't running. Check your startup and in MSCONFIG to see what is loading with Windows. Anything you dont need - get rid.

You might also consider a spyware and virus scan - just to be safe.

i can understand that but surely it wont using 41% of the CPU processes? Think i might do a full reinstall just to be in the safe side.
