[SOLVED] M/B USB ports not working ?

[alasdairt]

Hi
I've just cobbled together a PC with old parts. The core of this (m/b, cpu. fan & ram) was already plugged together and was all working OK a couple of months ago.

Now when I've put it back into a new case, the PC powers up but I cant get the rear USB ports to work. The keyboard doesn't work / doesn't seem to be getting power and it doesn't pick up the win 10 install usb drive I've put in. (I've got a freshly formatted ssd ready to install to and have tried booting both with this connected and not.

Any tips please? It seems weird that a couple of months in a box would kill the motherboard. Is it likely that something is conflicting?

Thanks

which hardware are you using?
try a USB2.0 port (black)

reset the BIOS by jumper, replace the BIOS/CMOS battery

It's an ASRock motherboard - 970 Extreme3 & AMD Fx-6300 cpu

I'm using the USB2 ports, Ive also check the keyboard works in another PC.

Will try to reset the BIOS

Thx

The CMOS reset did the trick. thx
