    A while ago my pc randomly crashed while I was playing a video game and refused to respond to the power button so I did the PSU test and the PSU was fine so I purchased a new motherboard and recently put it back together but the computer still won't start, the motherboards "sb_pwer" led lights up but when I press the power button nothing happens, I purchased a power button and tried that but no luck. I just purchased a motherboard speaker and plugged it in hoping it would help me solve the situation but when I press the power button it doesn't even make any noise. I'm utterly confused at this point id appreciate any help. btw not even the case fans or individual fans will start.

    I tried using another PSU from my current pc and it still did not turn on but for a while, it would turn the CPU coolers lights on but not post, everything else would not turn on at all, the different PSU doesn't even make the CPU cooler light up anymore

    btw I tested putting everything together on cardboard and still no luck
