I've found in both linux and Windows that some motherboards take OS instructions re: power states to be more of an "If you would be so kind..." hint rather than a "Do this. Now." instruction.

Except on Sandy Bridge/Ivy Bridge chips (which need the power saving features enabled to allow for multiplier overclocking) I do have a tendency to turn BIOS based CPU clock control/power saving off as it can be more trouble than its worth (see comment about Unreal Tournament engine games...)

Cool n' quiet disabled. Cores up to full speed.

Now if I can just get my graphics card to stop crashing...

It never ends...

I also disable it as I've had similar issues, I can see how it's important for laptop users but I prefer the "hot n noisy" approach...

heiowge, glad you got it sorted and that it wasn't the motherboard issue I suspected it might be.

Yeah, thanks.

It does mean I'll have to think more carefully about tower position for air flow, but that's something I've had to consider for a few days now.

Update:

Shut down the PC, and it didn't. So I pressed the power button. For 20 bloody seconds. Nothing! Had to pull the power cord out in the end!

Any thoughts? Is it related? :shock:

It is unlikely that disabling Cool 'n' Quiet made the system suddenly decide that it doesn't want to turn off. However, put settings back the way they were and see if it still does it.

It it does, if you've got a spare PSU around, swap to it and see whether it continues to play silly-wossnames. I just received an RMA back this morning for a PSU that was making the system it was running randomly power on and off or refuse to power on or off. Was driving me up the wall, and proves that even quality kit can go wonky sometimes after running perfectly for a couple of years.

tbh it hasn't done it since. Maybe it was just the PC having a bad day and moaning that I'll been lobotomising it again. :twisted:
