I know this is not W8 related, but I'm desperate. :(


My work PC was dead. Not sure what happened, but after replacing the PSU it worked again.
But I have two weird issues:


1. USB Ports: Plug and play doesn't work. If I connect a USB device in Windows, nothing happens. But if it's plugged before I boot, both the BIOS and Windows recognize it.


2. Internal Sound Card: It's enabled in the BIOS, it's recognized in Device Manager, but there's no sound. I've tried uninstalling and updating the drivers with no luck.


Specs:
OS: Windows 8.1 Core x86
Motherboard: Asus P5KPL-AM SE (latest BIOS)
PSU: Generic 500W (the old one was 450W, and everything worked fine).


Any help would be greatly appreciated.
