U should have posted ur PC configuration.
A typical Combo drive could consume upto 40 Watt of power.
Maybe your Power Supply Unit is not able to support it.
Try removing all the additional stuff like modem,sound card,any other drive if present etc(Don't remove the Combo drive

) and then try booting it.
Or else if ur friend has a higher rating PSU, try swapping and check.
Note:- Make sure that the Power supply connector to your combo drive is not loose
