Windows 7 64 Bit Computer Keeps Turning off

[JackV]

I am running windows 7-64 bit, and my computer keeps turning off. The tower lights go blank, led's turn off, everything goes black. It doesn't go through shut down process. Here are specs:

Processor: AMD FX(tm)-6300 Six-Core Proecessor 3.50 GHz
RAM: 8gb (ballistix or something)
HD: 1TB
Graphics: AMD Radeon R9 200 Series

If you need other components, let me know and I can post.

I am fairly certain that it is my PSU (which I bought around a year ago, it's a corsair CX 600), but before I buy a new one I want to make sure that is it. I have also seen things like usb keyboards causing this.

Thank you

I've never known any USB device cause sudden power-down in all my 20 years of messing with computer's, but by far the most common cause is a faulty PSU. So I'd go with that.

The Corsair CX series PSUs are of low quality and would be better to replace it to ensure your system's health, but lets not jump into conclusions, try these troubleshooting steps first to find out what's going on:

I suggest you start with the breadboarding test (described after step 23 I think) and then apply the steps mentioned in the link.

I should have noted, I can use my computer for hours on end sometimes, but other times it will power up, then a few minutes after it will just shut off. Will this cause a false negative on the breadboarding test?

For the time being forget about those steps, lets monitor your temps while using your system, use HWMonitor Pro or AIDA64 with their log feature enabled so you can review the data after/if it shuts down on it's own.

Have you noticed if there's any relation with the usage and the unexpected shut downs? say it tends to happen more often after playing a demanding game or running an intensive application?
