[Pag978]

Last night I was playing games for 6-7 hours and my keyboard and mouse randomly lost connection and the display was gone. My fans were still spinning and GPU was on but the display wasn’t working and the power button wasn’t working either. So I unplugged the pc and tried turning it on and when I do only the PSU fan turns on and 3 lights on the motherboard. The Boot,VGA, and DRAM lights are on.What can be the problem.

My specs are
Msi B550 a pro
Ryzen5 3600
Team force 16gb(2sticks)
Rtx 5700xt
Evga 600w
