What is the frequency you are trying to reach?
First, in order to overclock your CPU, you need the right components; the right CPU, the right motherboard, a good aftermarket cooler to keep your CPU temps down and a good power supply.
Your APU has a locked multiplier, which means that in order to overclock you will have to raise the base clock, which will cause the rest of the components clocks to raise too. This will cause instability.
500 Watts means nothing if your power supply is not a quality one.
Your motherboard has only a 4+1 power phase, with no heatsinks on the VRM of your motherboard. This will severely limit your ability to overclock. Not even worth the try. During a stress test using new overclocking settings the CPU will just throttle to cool down the VRM's.
Your APU has 3.1 ghz of stock frequency and a Turbo frequency of 3.8 ghz, and usually it is recommended to disable Turbo when overclocking. If anything I would leave everything at stock on BIOS and just leave the Turbo ON.
Your APU's max recommended safe temp is 71C and you are already at 67C. Don't overclock... Go back to BIOS and leave everything to default. Also make sure your CPU cooler is properly seated.
Being interested in overclocking is not a bad thing, you just need the right components. I can help you out with that if you wish and have the budget to replace the parts.
