My motherboard has stopped booting up (ASUS P8P67 PRO B3).

other parts:

i5 2500k
Corsair 8GB CMZ8GX3M2A1600C9
EVGA 560Ti FPB

Boots for about 3 secs then restarts, boots again for a second then nothing. Cant get into bios, never been overclocked (default), cleared cmos, rebuilt system out of case still no difference.

Contacted (email) tek support and customer service on Monday and have had no response.
