I have an interesting problem I've never run into before. I have a new M5A78L-M PLUS/USB3 motherboard with an AMD FX-8350 CPU and 8G memory. After booting the computer and getting into the BIOS and trying to change the time or date, the computer hangs after enter the 1st set of digits. I cannot tab or arrow out of the field. The mouse no longer works. I have to reset the computer. This happens every time. I can navigate to other tabs and change the boot order, etc. I've checked and I do have the latest BIOS version.
