Hi guys,

Here my Problem?!:
When I turn the PC on with the power botton on the case. All fans and the LED's activate for like a split second. Then shut down completely. After 1-2 seconds pause the PC boots normal and everything is fine. It is just like a hardware reset when you change the BIOS settings.

my PC:

Mainboard: Gigabyte GA-970A-UD3P
CPU: AMD FX-8350
GPU: MSI GTX 660Ti
OS: Windows 8.1 64-bit
PSU: Thermaltake Berlin 630W

I installed a new board yesterday. The Gigabyte GA-970A-UD3P.
Current BIOS settings:
Clock ratio - auto
core performance boost - auto
cpu unlock - disabled
cool & quiet - disabled
C1E support - disabled
SVM - enabled
cpu core controle - auto
core c6 state - disabled
HPC mode - enabled
APM - enabled

Maybe the power switch connector from the case is connected wrong? I can't tell since there is no + or - written on it. It's just a double pin thing.
I think other BIOS settings could boot without reset but I'm not sure. Could it harm to the PC to start everytime like this?

Thanks for your help.

Greets,

UPDATE FIX:

I turned on AMD Turbo Technology or whatever and it doesn't reset anymore. I've disabled it before due to OC. All other BIOS settings are disabled except AMD Turbo and HPM (high performance computing mode).
This should be the fix. No reset after cold booting and no reset while restarting :)
Update:

Default optimized BIOS settings still cause the same problem. So there must another reason.
When I click "restart" in windows the PC shuts down completely as well. All fans and LED off for about 2 seconds.
This shutdown happens the same way after pressing the power button to start the PC.
Fans start to run then immediatly shut down for 2 seconds and then the PC boots normal.

Searched other topics with the same but they had the issue in BIOS settings. Default BIOS still causes the issue.
