Let me ask you this. Does that motherboard have the latest BIOS. as it would need a BIOS update to even support a 8150. Also it appears you only have 1 Drive plugged. Now is that a HDD or your DVD drive?
I think the BIOS is already updated, my pc worked yesterday with the same CPU. and i onley plug a HDD drive.
If it was working with that one HDD before. I would try reseating the SATA cable or put it in a different port. Did you make any other hardware changes? Memory? Video Card? Card Reader even. I would unplug the case, reset the bios, and boot up again. Motherboards do not always come with the latest bios so if you didnt update the BIOS yourself, you should look into updating that.
i tried a couple of other sata slots and other HDD´s but that aint the problem because i am stuk in the POST screen.
when i start up the pc it onley makes one beep.
i don´t think i can update the BIOS because i can´t boot anything.
and i did place my videocard in a other slot.
