Why there may be a delay before loading the BIOS 15-20 seconds?

Include a PC, a delay of 15-20 seconds and talk then see the logo and then loads the OS.
There is a suspicion that BP is not suitable, although 650 watts.

The bulb MEM OK on the motherboard no chance?
The motherboard can every time to check what the maximum frequency you can operate the RAM, in this case, the light meme will be OK to burn during the confusion.

Long polls the hard disk (or SSD) or DVD drive, you can experiment to turn them off and make sure the BIOS loaded faster, and then alternately connect the device thus you will find that why does take so long to boot

In addition to the above, let me remind you that the main TO download the BIOS loads all devices has its own BIOS (or rather downloaders start recording) and can not be distracted by the information displayed on the screen.
