Hi,

I just finished a new install with this new motherboard and I have a very strange problem. Whenever I do a restart in windows 7 (Home premium 64bit) the PC enters by itself straight to bios!! No other messages before, nothing, just straight to bios. And even if I save and exit, the same thing happens. Only I press the power off button and shut it down, then it restarts normally. Any ideas?

I also have these problems that I have to correct in case is something related:
-reset doent work (I have to revert the pins)
-hd led is constantly on (I have to revert the pins)
-there is an unknown device in device manager

i5-2400
8GB Corsair XMS3
Club 3d 7970
Seasonic M12D 750W

thank you in advance
 
you have another keyboard to test with? silly as it sounds could be sticking delete key?

test in usb2/usb3 slots if its a usb kb,still could be bios issue with that make/model of kb
 
I put it in the USB2 slot, I will also try the USB3.
My keyboard is a Logitech Desktop Wave wireless...
I also removed the XBOX analog pad just in case it was that.

I dont think its a sticking delete key, since it only happens while restarting
 
The bios problem was solved with a CLR CMOS, but I have a feeling the system is quite unstable. Today it restarted just out of the blue while surfing in Windows...
Any ideas where and what to start checking?

thx
