Dual optical drive simultaneous working computer reboot without reason

A computer assembly, the work has been normal, installed on the previous optical drive failure, the use of new optical drive CD and VCD CD-ROM normal, but use it to install software, the computer automatically restart. Sometimes a reboot occurs when two optical drives are used at the same time.

First, the optical drive is checked by the substitution method, and it is found that any single one can work properly. Considering that the new optical drive can play CDs and VCD discs, but can not install the software, is suspected to be caused by insufficient power. Because the optical drive is reading CDs and VCD, the power consumption is not very large. When installing software, copying large amounts of data, the optical drive is very high and requires more current than when playing CDs. The fault disappears when the power on the computer is replaced with a high quality high-power power supply.
