Got a question, I replace a psu in emachine. Before I replace the psu I notice the standby power wasn't lit up or on. So, after replacing with new psu I notice the stand by power was lit up and on. Even thought it's lit up bright green. The machine still won't power on. Could the mobo still be dead. The mobo is a D845GVSR. I know it's a stand-by power. After replacing the mobo, I saw the light lit up. I'm like OK hope you work now! Well it didn't. Any info let me know. Have a great day. Todd
