My PC takes 53 seconds from power-on to full Windows operation.
I have Asus P7P55D, Intel i7-860 quad-core CPU, 8 GB DDR3 RAM, OCZ 120 GB SSD and Win 7 x64. I do not have any garbage on my system.
The 15-seconds time lapse out of 53 seconds is due to BIOS hardware enumeration. Then a short beep follows. BIOS post screen appears. Then 'Starting Windows' is seen.
Therefore, 60 sec is not long for your system with conventional HDD, in my opinion. I do not know if your BIOS also takes long and holds off from booting straight into Windows, like mine.
