Pc problems help

[Im_2__]

Not sure if i posted this in the right place, im sorry if i didnt.

Earlier today i had my pc on and i plugged in an aux cord to use on my speakers, my screen turned light blue and was unresponsive , i had to do a hard reset, i tried to reboot and now my mouse and keyboard flashes on and then off and it doesnt register the monitor.

I have a h55h-m v1:1 mobo and windows 10. Please help !
Quick edit. I plugged in my phones usb charger and it charges my phone just fine. Im kinda stumped on my why mouse and keyboard wont work.

All connectors sitting tightly in the ports of the motherboard?

In which port did you try the AUX cable? Front or rear green port?

Did you unplug the AUX cord again?

reset BIOS
