No Signal, then shutdown 10 seconds later

Hi,

Recently my trusty old system (as per my sig) has developed a problem. Completely at random, my monitor will loose signal, though I can hear music/a game/video still playing in the background. Around 5-10 seconds later, a shutdown occurs.

I've been monitoring temperatures over the last few days, all seem perfectly fine. I started monitoring voltages (logging the current voltages/temperatures to a text file) and I noticed the following:

1. The 12V rail 'spikes' to 12.1v (doesn't seem too drastic to me)
2. My 5870's memory speed is reported as 3186 (was previously 1200 as per a standard AMD 5870's spec)

I'm not sure if these values are reported incorrectly, as a result of the crash, or if they are related.

Here is a link to the logs, if anyone has the time to look over for them:

At the moment i'm considering either a new PSU (current one is a 5 year old Enermax Galaxy 1Kw) or a few GPU.

Any help/advise would be appreciated! Many thanks :D
 
What does it say in event viewer, for the time of the shut down.
You could try running a Gpu benching tool like Heaven 4 and use MSI AfterBurner to record temps and voltages.

Also download and install Whocrashed, this might also give some indication as to what is causing the fault.

Speedfan will monitor Psu voltages, so should give you an indication as to whether your Psu is failing.

Nothing listed in event view for the time of the shutdown.

I've already included full temperature and voltage logs that stopped recording at the time of the shutdown/crash in my original post.
 
Update, tried running my system at stock (no overclock at all) and the same issue occurred. Took 12 hours this time, at the time of the shutdown, the system was completely idle.
