I just built a new PC using a Gigabyte 970A-UD3 motherboard, it's been up and running for about a week now. I've since been having an issue when inserting a USB flash drive into the front panel ports. Sometimes it causes my D:\ HDD to crash (it resets as though it was just connected, Windows is on my C:\ SSD drive) and other times I get a BSOD and the machine restarts.
This has happened using both front USB ports and with 2 different USB drives - one USB 3.0 the other USB 2.0. It doens't happen all the time either, only sometimes which is making it difficult to troubleshoot. It has yet to happen when using my external USB 2.0 hub, but as I said it doesn't happen 100% of the time on the front ports either.
I've used disk management to ensure there is no drive letter conflict, which was my original thought before I got any BSODs.
Here are the full system specs:
Motherboard: Gigabyte 970A-UD3 v1.1
CPU: AMD Phenom II X4 980
RAM: 16 GB Patriot DDR3 1333
GPU: nVidia GeForce GTX 580
Primary Hard Drive: Crucial M4 128 GB SSD
Secondary Hard Drive: 2x WD Black SATA III 1 TB disks using onboard RAID 0
OS: Windows 7 Ultimate 64-bit
I have the .dmp file from the last BSOD available here for anyone who would like to help, I don't exactly know what to do with it myself.
Maybe the USB sockets on the FP are bad. Try using the same devices that caused it to crash, in the Back Panel USB ports and see if it happens.
Faulty or cheap USB sockets on the case can often cause this problem when inserting or removing devices.
I tried moving the Front ports to a different connector on the Motherboard and it still would cause crashes/BSODs. Likewise I tried connecting a rear-panel USB adapter to the motherboard connector originally being used for the front ports and have yet to have any problems with them.
I contacted Antec and they are sending out a replacement front-panel assembly. Until then I am avoiding using the front USB ports.
Glad you found out before you ended up damaging one of the USB peripherals you connect to the ports.... bad ports often damage the equipment connected to them because they have a power source, so , I must say you are pretty lucky.
I have the same motherboard and I am having continuous problems with the USB 3 ports no matter which I use. When I have my USB 3 external hard drive connected at the back it will often cause the computer to just reboot when I am accessing it. It doesn't do it when it is connected to a USB 2 port. Same with the front ports too. I can almost instantaneously crash my PC if I plug my phone in to a USB 3 port and try copy something to it.
