PSU Issue

[fish aficionado]

Hey guys.

Today I tried to start my computer and it didn't work, all fans were functioning except the CPU heat sink. Tried two more times and nothing so I thought maybe something could be wrong with the PSU, I took a closer look at it and noticed the cables at the 10th and 11th pin were somewhat dark. http://imgur.com/x8DuS I tested them and got 12.28V on both.

Do you think it is the PSU? I'm afraid it could have damaged something else in the motherboard.

Thanks in advance.

I'll admit that the discoloration of the wires looks a bit off (and something that I would be concerned about too), but if everything else checks out and works, that sounds more like a bad CPU fan header to me.

When you say it won't work, do you mean it won't boot at all, or that you get an error on boot?

It won't boot at all. And in the last days it was shutting itself off randomly without a warning. What scares me the most is not only that the PSU may be faulty but that it could have damaged something on the MB. That would be really bad news.

Yeah, in that case, I'd say it's definitely a bad PSU, and I'm worried that it might have taken the board with it too, unfortunately. I would suggest getting a new PSU first though, to see if that's all it is, since that's the easiest and probably cheapest fix.

Oh boy, not the board!! I guess I'll try with the PSU, if it took the mb I might as well throw the whole thing to the trash and go cry in a corner. Do you think there's any particular reason this happened? Besides just a faulty PSU of course.

Thanks for your time.

From the way you describe it, it sounds like the PSU was just failing on its own, and finally just gave up (and possibly caused more damage when it did).

There is a lot of troubleshooting to do before you go cry in a corner!
