Computer just shut off...won't turn back on

[AOD_pyle986]

As the title says, that's exactly what happened. I'm sure hoping that it was the PSU. Everything I the computer is new (within a year) aside from the PSU which is 6-7 years old. I am going to order a new one and hope that fixes it. Otherwise, any other potential issues that could have caused it?
Nothing was abnormal at all when it shut down, just boom, all power out.
Thanks

From your description I would say it is most likely the power supply. Does the motherboard have any status LEDs on it? If it does and none of them are lit, chances are it's a dead power supply. If any status LEDs are lit it still could be a bad power supply since it is possible for the supply to push one bus, say the +5 volt one, while one or more others are bad.

Inside the case is just a dark sad group of components...no lights at all

Then I would say it's a dead PSU. If you want a super high quality new PSU on the cheap, the EVGA SuperNova G2 line is the best. Depending on what you have, I'd go as far up as the 650w. Anything above that is overkill unless you run a Dual GPU setup.

I would agree with Kaos. If you have any local computer repair shops, you can typically take it in and have them hook up a power supply tester if you want full confirmation. Any good place won't charge for just checking to confirm.

I've seen other things cause a system to not turn on, but typically it has occurred after I've rooted around in a case. Doesn't sound like this is the case here.

7 years? Holy shit - I would buy a new PSU from the same company. That's an insanely long-lasting power supply! It's definitely your power supply lol
