Avoid Load CPU Spikes? Older Computer

Is there some way i can make my computer focus all its processing on Traktor versus other processes? Im running an old Amd Dualcore at 1.8ghz with 1gb ram and even though its below recomended for traktor it can run it at a half load and have everything run smooth with no pops or cracks in playback. but every once in a while without even using any effects or running any other decks the load will just spike at random and im assuming its because the computer is trying to do something else in the background that i dont need it to do. I run Asio4all on default settings with multicore processing setting ON. Im using traktor 2.5 on windows 7.

 

when you read the tuning tips in the knowledge base, there are tools mentioned that can help make out certain drivers or so that can cause spikes that make trouble!

 

You can probably double to quadruple your RAM for somewhere around $20. Check out ebay or a site like newegg. That would make a performance difference I think.
