I bought a Antec SmartPower 400W power supply about 10 months ago. When I try to turn on my computer, all the components will blip on and then turn back off. However, when I press the power button again, the computer turns on fine. The problem happens each time I shut down from Windows and turn it on again. I'm worried that it might be the power supply since others seem to have longetivity issues with this particular model. Right now, everything is unplugged except for my hard drive and a couple fans and the problem is still there.

If it the power supply is dying, is SeaSonic still the way to go these days? Computer specs are listed in sig. Thanks .
