I have a DQ965GF mainboard with a P4 630 processor with a strange issue.
BIOS version is C096510J.86A.6094.2009.1239 which I think is the latest version from last year.
When I switch the power switch from the PS on or plug in a power cord with the power switch in the 'ON position' the board
powers on for about 10-20 seconds then shuts down again.
The PS, CPU and case fans spin as well as the CDR and HDD (which worries me), but it doesn't get to the POST screen with the
rotating post code in the right corner before cutting back off.
If I press the front panel button after it shuts down it powers on normally and there are zero other issues. It boots to Windows or Linux without any issues and no hangs or problems even in Windows. I've used this computer as an experment platform for several different operating system hence the different OS.
I have the BIOS setting under Power>After Power Failure to "STAY OFF" so it shouldn't be powering on from a cold start like this.
It doesn't do this if the board has been shut down from software(Windows or Linux) or the holding the front panel button.
Power Supply is a 550W ATX (I think it's a Cool Master). It has done this with several different power supplies including a the one I use in my main computer though so it's not PS dependant. It's not the memory which I've changed around and with different sticks of different brand/sizes/speeds.
I am using the onboard sound and video so it's not that either. The only things plugged in most time is the HDD and CDR both of which are using the EIDE channels not SATA.
I've found another thread (cannot find it again) where another Intel board was doing this and the person was told it's normal, but what I'm more concerned is my HDD and CDR drive. The power on is not long enough for the HDD motor to come up all the way to speed and the power kicks off again.
The issue happens with or without the front panel connectors for the power switch attached to the computer. I've plugged in the power cable or switch on the PS without plugging in the front panel lights and switches and the issues still occurs.
Is this really normal as the other thread suggests or is there somethig else afoot? Also, if it IS normal is my HDD going to be damaged by suddenly losing power whilst spinning up each time I pull the plug, switch the PS off, or have a power failure?
This board is a throw away really due to it being older now, but if I can fix this problem I have use for it.
If anyone has a fix for this problem please let me know. I have searched this forum, but the issue is not being found by the search function and I'm getting a zillion irrelevent hits or none at all.
*edit* - I found a work around. I changed the BIOS Power>After Power Failure to Power On and the issue went away it's is being caused by that setting.
Is there a way to make this setting behave properly? My solution is not really a solution it's only a work around.
