Thanks for the suggestion. I agree that's probably the best thing to do.
Since I'm no expert in the area, so I have another followup question - does the possibility exist that my motherboard or other pieces may not be powerable if I were to buy something like this? (http://www.frys.com/product/7507846?site=sr:SEARCH:MAIN_RSLT_PG)
I'd really prefer not to have to buy even more pieces.
