If you have never tried this before give it a try NOW! I think you may be in for a nice experience. Big-Fix found three errors on this ME machine after re-installing, and I fixed them all in two mouse clicks and a few minutes to add Direct-X 8.1!*
I just bought an eMachine computer (T4080) and it came preloaded with Big-Fix. It lets me know when stuff needs to be fixed and subscribes to both the 'Big-Fix' & 'eMachine' fixlets. I LOVE IT!
