Saturday morning my desktop machine was down when I woke up. I must have hit the button a dozen times in the fleeting hope that it would magically startup again. This is the same machine that died earlier this year. I wanted to get started working on it right away, but I had to cut the grass before it got too hot.
The day before I heard a pop in the room, but everything electronic was working just fine, so I thought it was something that fell. Apparently I was wrong.
When I did get to working on the computer later that day I started with my media machine. I swapped in components in and out of a known working machine. All the components seemed to be fine. So I put everything back in the original box and moved the power supply over from my media machine. Lo and behold, it lives. I really like that power supply over the cheap supply that came with the case, the machine is much quieter now. So I ordered 2 more from newegg.

Bad power supplies are really hard to debug. If your computer has “unclean power” you’ll never figure it out until you replace the power supply. I hope you have learned your lesson
Always buy nice name brand power and you should be ok. Not a guarantee, but much better than getting no-name super cheap.
