I recently upgraded my computer. I bought fx8320,new mobo, ddr3 ram and SSD. The only old component is my corsair vx450. After the install of win 8 I experience random usb port failures. They just stop working and it can happen anywhere from 1h to a whole day of ontime, then i need to reboot the computer to make them work again. I also use an external usb hdd.
Im wondering what you guys thinking is the problem, is it PSU or mobo related?
My old computer worked fine with the psu. Really in need of help, thanks

It is only the back panel usb ports that failed, I've updated to the latest bios and chipset drivers.
The chassis fron usb ports still work.
