All stock cooling. Only the GPUs have been overclocked. They do run a little hot 60C.
The system powers off on the same test everytime
Its the "Feature Test" that happens just after the person surround with green dots.
I think the test is some sort of blending test, i see a bunch of colours for a second and then it powers off. Its doing it on the same test everytime.
The numlock light stays on, but I need to poweroff the PSU and power it back on in order to start the machine again.
I'm wondering if its caused by the GPUs over heating, but how can I tell? Is there a program that logs system health to a file while I run the 3dmark test, so if it crashes, I can just reboot and look at the logs?
I have a strange feeling it could be the PSU as well, because I used to run the same system with a 480watt Antec PSU and it did the same switch-off trick whenever I tried to run the window experience index test.
