It seems this CPU could be "faulty" due to prior overclocking. To verify, another CPU should be tested to determine if the original (G3258) is defective or if the motherboard itself is the issue. If alternative CPUs aren't accessible, consider testing with a different motherboard, provided one is available. Otherwise, it appears there are limited alternatives.
