I don't know what happened , one day I turned my computer on and my keyboard and mouse weren't working. After some testing I found out my usbs are only outputting power , ex: I can charge my phone in them , but my keyboard , mouse and usb sticks won't work or even be detected by the machine. I can't even access bios. I tried reseting it manually but with no change to the behaviour. What is this? I can't find anything in any forum.
Please note I don't have access to bios or windows

System specifics, please.
Intel i5 6600K
16 gb DDR4 HyperX (2x 8GB)
MSI B150M Mortar Artic
Corsair tx 750W Bronze
Gigabyte OC 1070 8GB

Never tried overclocking on the cpu or the gpu. But windows loads up normally, just the usb´s completely dead , preboot and after boot

Did you try all USBs? Front panel aswell? Or is it only affecting motherboard USBs?

Get a hold of a PS/2 keyboard and try booting with that connected to the PS/2 port that MSI has on that MB. They identify that port as a "Gaming Device Port", but it may also allow the use of a PS/2 keyboard.

If you can machine-gun the "Delete" key and get into BIOS, you may find that USB has been disabled completely, a situation that can be rectified, at that point.

you might give a look at the board with a magnifier to see any abnormal parts but there is no way to fix a motherboard if she still under warranty ask rma .
I already looked for handicap capacitors, no luck.. sadly warranty voided 1 year ago, so... yeah new motherboard incoming
