To track down this problem, we need some more information about your system and install.
Can you run the following commands in 7.04 and attach the output to this bug report. lspci -nnvv > lspci.txt dmesg > dmesg.txt sudo dmidecode > dmidecode.txt You mention the system freezes after hitting the "start" button, does the system come back alive after trying to burn the DVD? If it does, please attach the output from dmesg after it re-awakes as there may be error messages in the dmesg output. If it never re-awakes after freezing, this will be interesting to know.
