I have disconnected all SATA and peripherals and left only 1 DDR module and 1 graphic card and replugged all connections steady. I have tried this with other DDR module too, different 6 pin connector also for graphic, other graphic card(that didn t need the 6pin additional power connector) and the problem is the same.
I have watched closely after power on and this is the result:
When powered on, first comes the graphic card cooler test which spins on different rotations for a second, and then spins normal. After 5-10 seconds, the cooler on graphic card almost stops and the MB tries to recheck again the cooler. This can happen 1-5 times, but when the cooler doesn''t seem to stop, MB posts and I get a beep from speaker and goes well afterwards.
As I have said, sometimes, probably after more than 5 cooler check tries, I get a long beep, probably, as Vezina said, there is a cooler problem on graphic card.
In conclusion, either the CPU (because all theese came when I have changed the CPU) or MB (because of the BIOS update to F10d beta, though before installing the CPU nothing wrong happened) has a problem. Do you think reflashing BIOS or clear CMOS or what else can I do to sove this?
Thank you
