windows was loaded sometime during 2003 i have recieved all the updates, i went to the web-site and it said there were no avaliable updates at this time, i don.t have problems with no other files, the cdr/dvd/rw works fine when you are burning cd,s no problems, it is just when you start playing them back on this pc you get that skippinng, start/ stop. breaking up type of playback, but that is not recorded in the cd or dvd you are burning, when i take the cd or dvd that i recently burned and put it on my cd- player there is no skipping, or start/ stopping as i am typing this reply i am getting a 1-second delay in the letters appearing on the screen.
