HELLP. My computer shut off randomly one day, I have not added any hardware recently, no storms or anythings, had it on a powerstrip. Now, nothing happens when i push the power button on the computer, the voltage switch in on the correct toggle (115V). I looked at the the power supply and the indicator light was particularly dim. I tested the power supply by bridging the black and green pins and the fan kicked on just fine. I am not sure which is bad, the power supply or the motherboard. The fact that the fan came on was a good sign, but the dim light is what worries me. Does this sound like more of a psu issue or motherboard issue?? I don't want to buy the wrong thing, and I don't have a backup to test, thanks

Hi fleedd,

You can try testing a spare power supply and see if the current power supply on your computer is bad.

As DBCooper has stated definitely see if you can borrow/test another PSU.

Your symptoms indicate a failed Power Supply.

Also inspect the motherboard for any damaged/bloated caps.

Another yea for a PSU issue. Jumping the PSU with no load only confirms it is capable of powering on but doesn't prove it is capable of powering on the system.
