Hi, I have a wierd problem. Recently build a PC with Q6600 cpu and Intel DQ35JO mobo. Since point one - it won't shut down. Choosing option in windows start, sowtware shuts down as it should. Hardware not - fans are spinning, power leds on MOBO are on. And that is it - I have left it for night -still running in the morning. Changed psu, tried different ram's, tried clean windows option, tried unplug everything and pluging in again. played with all BIOS options I could imagine and ones which shouldn't affect it at all :)  still the same. Tried to chnage what power buttons do - nothing. Have tried to re-flash BIOS (as there is newerst already) but...it seems that someting is blocking it. Tried re-flash in all modes from INtel website, but none of them seems to work. It just resets BIOS to the default. The reason why I think so, is that it have a custom made logo, and after flashing a BIOS - I assume, it should go back to original, but it won't. Also I have looked at USB ports looking for oxidations, damages, but nothing. There was however few times when PC did shut down properly, but I couldn't pinpoint the reason. Any help or expierence with this?

Just to be clear, windows shutdown (software) works, but the power button doesn't shut it down? Have you checked the power button motherboard cable to make sure polarity is correct and that its plugged into the right pins?

Hi, Thank you for reply :)  Yes, I have tried to swap polarities and even tried with different switch in case someting is wrong with switch itself.

Just to clarify - When you shut down pc through Start - Shut down - everything shuts down to the point where main power need to switch off - so - software is closed, but pc elctrical parts (fans, leds) are still working.
