Coil whine then PC shuts off

post #1 of 7
Thread Starter 
Hey guys.
I'm helping a friend troubleshoot his PC. I have a strong feeling it's the power supply but I want some other views on it.
The problem began when there was a coil whine coming from the PSU area then the PC randomly turned off during the loading of a game.
After turning it on again, it ran fine into a few minutes into gameplay, but then the coil whine started again and it randomly turned off soon after.
After that, the system wouldn't turn on again until it was unplugged and plugged back in.

Here is some information about the system:
AMD Phenom 965 X4 OC'd to 3.6ghz
Zotac GTX 470
Thermaltake TR2 600w PSU

Any thoughts on what might be the problem?
Thanks in advance.

Hi there tongue.gif

Well the Coil Whine it's normal, is an annoyance. Some brands do offer better reliability in terms of coil whine. Happens when electric current makes the materials physically vibrate. And you notice that more when you draw more power from the PSU.

Now if you said that the PC is turning OFF, you may have a faulty PSU, if you have another one there, try changing it and test thumb.gif

I'm actually going by him tomorrow. The problem is transport to get there, and because of our country, it's also hard to get a solid replacement asap. I was thinking of going with my intuition and buying a PSU before testing the old one because it'd be pretty hard to get it afterwards.

I mean, what else would prevent the system from starting? Not even the fans would have spun up.

IMHO sounds like the PSU is not giving you enough power and it's faulty, but there are other things that could interfere with this.

For example you said the cpu is overclocked,if he had a stable OC for a long time maybe he need to readjust the volts. Depending on how hard is it.

What i would do before expending money is running the pc on stock clocks and see if the problem is gone, and if the problem persist then i would buy the PSU, just because i don't like to spend money and then having to return it hehe.tongue.gif but if you still want to buy it and see how it goes, let us know rolleyes.gif

If that is one of the old TR-2 PSU´s you have there rip it of the machine as fast as you can and replace its terrible.
The newer TR-2 units are okey but the old ones are crap.

If its called W0388RU its the crappy one and in that case you should smash it with a hammer.
