I like an ***** installed System Mechanic 6. Luckily I never installed the Firewall or Antivirus so i not having huge problems like many others. But one thing the "start-up optimizer" did was disable the Windows start-up and close sound. I positive the file locations are and even changed to some wav. files I had laying around but still its a no good. Also let me mention my boot-up isnt any faster. Ive tried system restore and installing the program but still the same smack. Someone mentioned at another site it my have changed my boot.ini whatever the hell the means. If anyone can help that would great.
