PROBLEM SOLVED!!!

So here is what made a difference, from 18 seconds down to 6 before reaching post screen, which is normal for this mobo i suppose.... Apparently more than half (4/6 tested) of the SATA ports on my mobo cause the PC to lag when the boot drive is connected through them. so i just switched from one port to another and finally when i checked it int he port that the SATA-DVD drive was using, Bingo, 5 seconds to post screen....

I think ill contact the manufacturer to have them send me a new mobo as this one seems defective.

Thanks everyone for your help with this problem, it turned out to be something more simple than I thought.
