I have an emachine T1115 an recently I had a power outage but after the power came back on I couldn't start up my computer. I have a 150 watt PSU installed in the sysytem and I wondering if this could have possibly gone bad because of the power outage. I have a 250 watt and 300 watt PSUs here and I want to know if I can use these to try to start up the system to test if the PSU really is the problem or if the reason for the computer not being able to start is something else. If u think it is what could it be?
