In a previous post I asked why I am getting power shut off after no more than 30-45 seconds. I swapped out the mainboard with another of the same model. This time I did the following: I added one component at a time, such as fans, etc., to see is something was tripping up the power supply. I added the LiteOn Sata optical drive and it spun up the CD that was placed in it. But as I tried to eject the disc the powersupply shut down and needed a minute or two to reset. Is this a power supply problem?
(MSI M9 mobo, 1g ram, CPU fan, WD IDE hhd, liteon sata optical, that is it).
