Hi all,
I have a GA-880GM-USB3 which has had no problems. I turned the machine on the other day and it booted fine, then left it running for a few hours. When I came back to it, it was 'frozen' (unusual, as it is running Ubuntu Studio with 8 Gigs of RAM, and it wasn't doing any work). When I rebooted it, and every time I have rebooted it since, it goes through the POST process and gives an OK beep, then goes to the text based display screen where it displays motherboard and processor type, with the boot/BIOS options at the bottom of the screen. No matter what I do, it won't except any keyboard input, either to go into BIOS management or select boot or recovery options. I've tried 5 different keyboards, and all the USB jacks available on the MB. I've stripped the motherboard down to just processor and RAM, and it does the same thing. To test further I pulled the RAM out and it POSTed and complained about no RAM, so it appears that the motherboard is healthy and passes POST tests. It just appears to not accept any kind of external input (i.e. keyboard). I've been building computers from scratch for twenty years and I've never seen anything like this. Any ideas??
