I suggest you seek professional help for what appears to be a serious
hardware problem.

In a pc with a small power supply, an older or cheaper one, I would imagine
that the total wattage of the installed items, m/board, video, sound, multiple
hard drives, cds, items drawing power from usb bus, is drawing the limit of
the power that the supply is able to send, when the extra 15watts to spin up
the cdrw is drawn the power supply overloads and the thermal cutout kicks, it
then cools and resets. you need less hardware or a bigger power supply. To be
sure add up the MAX wattage ratings stamped on all the cards drives and usb
items, and compare that to the rating of the power supply
