Dvd rom restarts computer

fresh clean install of xp home and every time i put in cd/dvd restarts computer???

I have also re-re-installed xp with all updates, rom works perfect for install then once in windows makes computer restart when ever a cd/dvd is inserted, ive even taken them off autorun. when it restarts there is no log error…
updated firmware for roms, 2 doing exactly the same thing… i ran xp pro for 4 yrs with no problems needed to switch to xp home.
