Hi everyone, Here is my problem: When I power on my desktop computer (i.e. when I push on the power button), it takes 15 seconds of black screen before the BIOS display. When the BIOS display and load, everything is normal and the computer starts quite fast. So I wonder what could take 15 seconds at the beginning? I think it's kind of related to the hardware (the POST check or else)... Does someone ever heard about that kind of issue? Thanks for help Config: ASUS P7P55D E-Pro Modded BIOS 1.602 SLIC 2.1 ATI 5750 HD 2 HDD 4 Go RAM Windows 7
