This is a fresh Windows due to another issue, so everything should be fine. I was reading discs yesterday. Now, today none of them not even a USB will show up in the drives list. under DVD/CD-Rom drives I have 2 devices with ! and under USB controllers I have 2 devices showing Unknown USB Device (Device Descriptor Request Failed). Thinking it was that, I unplugged the USB drive and deleted all 3 from device manager but the 2 internal show up with the !'s. I opened the side and made sure the connections were seated. I then went into BIOS and all the drives were showing up. What could be causing this?
