My current system was built in May of 2012 and has been rock solid until like now. I have had 4 out of 6 USB ports fail on me at once. I can't scan, can't print and the only two that are working I have both my mouse and keyboard in them because I had to transfer them yesterday the ones I had them connected to for almost 2 years. My printer was working fine yesterday and then that port failed today. I have tried booting and rebooting to no avail. The motherboard is a Gigabyte Z77X-UD3H. If anyone can recommend to me a good solid Z77 board I'd appreciate it because if the last two ports go I won't be able to use my keyboard or mouse and then I'll have some real grief to deal with. Any ideas would be most appreciated. Thanks.
