I've got an issue where by PC is turning off randomly.

It seems to work okay and then from no where it turns off. it's not a restart of windows I just turn it back on and away I go again.

Where do I start troubleshoot this issue?

I would suggest this is heat related.

Hmmmm

I have wondered that. Is there a way I can view my PC temperature?

Could be faulty PSU too.

What should a temp be?

I'll monitor this for over the next few shut offs. I've think it happens more when the room is warmer hence my thoughts being heat related as well.

From around 30C-mid 40'sC at idle.

Then anything up to the maximum for the CPU (usually around 70-100C max), depending on how much you are loading it.

If it is overclocked, it will run a lot hotter usually.

What sort of CPU is it?

I had something similar and it was the psu. I replaced it and the problem was gone. They are not expensive, as little as $15 depending on your pc.

Can I just suggest that (even though it might sound silly) you have a lose power connection at the wall or a bad socket on your power board? Perhaps a bad power cable to your socket/power board?
It's pretty common for the boards to lose their "grip" on plugs and work their way out.

CoreTemp is a great software to monitor CPU temperatures. If it happens when you're doing something such as opening a browser or playing a game, it might be more serious than what I described above.

I have an overclocked X6 (6 core) PhenomII in my PC. It's at 3.9GHz and I'd never let it hit anything higher than 70 under 100% load. I can safely max it on a regular day at about 45 degrees. It's sitting idle as I type right now at 22 degrees.

Good luck!

Open the case and check the CPU fan is spinning, and that there isn't a load of dust on the heatsink(s).

Okay - I've narrowed it down (I think)

It turns off when I'm playing games. SO maybe the graphics card is on it's way out (see my post about graphics card fan).

Is there a way of testing my graphic card heat and other performance issues? NVIDIA card.

Would this make a system turn off though?

More likely the PSU, if it was the graphics card the system wouldn't just shut off, try a different PSU and see if the same happens with that.

Where are you located? I'm sure someone could possibly lend you a PSU to try. Also what are the specs on your PC? If you can tell us we can probably recommend a wattage to go for. TBH most people overspec their PSU - unless you have a monster rig a 550W or even 500 or 450W of a decent brand should be fine

Could be any of these things - PSU, graphics card getting old, CPU overheating. Open Hardware Monitor can monitor temps and give you an idea if it's CPU/graphics temp.

PSU Reviews.
Why PSU reviews are mostly wrong.
