Computer Spring Cleaning

Forums:

Is there an affordable local who will tune up my pc? I tried to do it myself, and now it runs slower than ever. It is only a year old, so it should be fast.
Best Buy will charge me 145 to do it. I don't have that kind of expendable cash, even though the PC is a vital part of our business.
I thought I heard of someone at 2014 who does it, but haven't been able to pull up the article .
