Apparently you didn't bench-test before installing the hardware in the case, that makes troubleshooting a little more difficult. But my guess is the thermal paste between the CPU & heatsink was applied improperly (or not at all). All AMD CPUs use the "middle dot" method.

Actually, you don't have onboard graphics. The ports that are built into the board are for use with an APU (CPU with graphics). You have a CPU (no graphics) so the onboard graphics ports are useless. The GT 610 is actually a rebranded GT 520 so it's really not much of a gaming card due to it's low number of CUDA cores & 64-bit memory, but it's a decent HTPC card.

Do you have onboard video (or a card installed)? Booting requires some type of video. Otherwise, the usual suspects: shorted board to case, power-supply problem, bad/wrong RAM. Try removing the motherboard from the case, place on non-conductive surface, add video (if not onboard), monitor, and a minimal amount of (correct) RAM and connect P/S; don't bother with the HDD/keyboard/mouse at this point. If it boots to some type of startup screen, then check previously mentioned issues.

If it has onboard video then do not use the video card during the first step of the bench test, you will add it later. CPU with heat sink properly attached, one stick of RAM, power supply, monitor. ** see link at the bottom for bench test details **
You will need to review your assembly again.
Are all of the motherboard posts in the right places in the case, none empty on the motherboard and no extra underneath the motherboard where there are no holes for mounting screws.

Um I can't do that cause when I have the 4 pin connector plugged in to give the cpu power the pc turns off after one second but when I have it unplugged everything runs fine but I can't get into the bios cause there's no power to the cpu
