I have installed a second front panel with two usb 2.0 sockets and audio plugs. My computers old duplicate front panel is still installed but had faulty audio so have unplugged just the audio from the motherboard left the USB 2.0 sockets to still use though. I have 4 USB 2.0 sockets now connected for the front connected to 2 separate USB 2.0 plugs on the motherboard. What happens though is the computer locks and wont even enter bios or go to windows if i have something plugged in like a keyboard in one specific USB socket in the new front panel before booting, it works if i dont use it though. Any idea what could be causing it?
