Hi everyone,

I experienced repeated power outages in the neighborhood last night and when I went to turn on my Dell Dimension 8400 desktop nothing happend. I tried uplugging the desktop from the APC surge protector, resetting the surge protector, and plugging in the desktop to a different recepticle in the surge protector as well as directly into the wall, of course nothing happend. I know the surge protector is getting power becuase everything else plugged into it is working fine.

When I press the power button the desktop doesn't even attempt to power-up, it simply behaves as if there were no power.

Does this mean I have a blown power supply or are there somethings I can try that might resolve this?

Thanks
Chad

It sounds like you may have a fried power supply, completely fried motherboard, or both.
The problem is you really won't know i8f the motherboard is damaged until you replace the power supply.

Can I try using one of the power supplies from an older computer to replace the busted one? Are there any compatability issues I should worry about?

You will need to try and match the wattage ratings on the power supplies as close as possible. Also make sure it has the same number of pins on the main connector, and the correct connections (IE the 4pin P4 connector required on newer computers). As long as the connectors match and the wattage ratings are close (within 50 watts) it should work to determine if your old power supply is bad.
