Hello!! I am new to this forum and would like to seek assistance. 
My PC suddenly has no signal to monitor and no power to keyboard and mouse. Except this, everything is alright including power on and loading windows. I can connect to this PC now via remote desktop and it works as usual. The PC connected to the Internet via a wifi USB, it seems that USB port is still working.
Actually this issue happened again and again in last few years, but this is the first time since I replaced the motherboard in last year. Previously I thought it was a motherboard problem so I replaced it.
I have tried to remove all cables and pressed the power button for 1 minutes but it does not work (learnt from this forum). I don't have any idea what's up. Please help.
