If I press the power button again they all kick back in and start up again.    ive checked the psu connections and the motherboard screws and the motherboard connections, I don’t know what can be causing.

Hi @gias_girl Presumably you are checking the CPU temps etc in BIOS when you say “all temps are normal”? Start the PC and press Del key before the PC boots into Window, i.e. when the MSI logo is showing at startup to get into BIOS. If it boots straight into Windows then you may have to go in through Windows to get to the BIOS menus Here is how to do this. The BIOS version should be on the System Information page in BIOS. The user manual details how to update the BIOS if required Maybe try a game to put the hardware under a bit of stress (lots of video action etc) and check what happens i.e. do the fans stay on and speed up if required, is the video still OK and not lagging, is the PC staying on and not shutting down etc

Do you have all the fans connected to the same moles plug? Try spreading out the power connections over all of your available power molex. You could be overloading an individual plug and or the plug may not be making proper connection
