Faulty motherboard?

post #1 of 4
Thread Starter 
Hey guys, I have Gigabyte motherboard (AMD 780G chipset, complete model # in siggy) that is about 3 years old now so I would surprised if it is faulty....What happens;

a) plug in usb device (headphones, usb flash drive, etc) into the front USB ports (connected to usb header on motherboard)
b) Windows 7 crashes but doesn't restart

The power seems to stay on and I can hear my HDD's still spinning but my screen is just turns black and no BIOS appears (it completely crashes Windows 7). I have to restart my PC. This happens 1/10 times but another 5/10 times, whatever I plug into those 2 front USB ports doesn't get recognized, even if it was used in that exact port the day before....I take out the component, and keep re-connecting it until it works, which it eventually does. This seems to be a common issue, regardless of OS and most people point to a not powerful enough PSU but if you look at mine, its fine and its new (~1 year old).

Anyway, I think it is either;

1) physically damage (ports on the front are wiggly)
2) IRQ conflict (I have many usb devices, about 6, but have no experience troubleshooting IRQ issues)
3) faulty USB header on the motherboard (only the one that is connected to the front USB ports because if I connect anything to the ports in the back, it works perfectly)

Does anyone else have any ideas on why my PC would be completely restarting only when plugging USB devices into my front ports? confused.gif

I have identical board in my HTPC. The chipset northbridge runs notoriously hot. Point a fan at it.

Does it control any USB functions? I seems to be a windows only issue however....It doesn't happen under my linux partition (although I don't connect very many USB things) so I am thinking it is a USB driver issue...Don't know why it only affects my front ports, but then again, I don't fully understand what hardware is controlling those ports (thought it was just the header port on the motherboard) and how it translates to a Windows 7 issue. confusedsmiley.png

Scatch that, seems like it is happening under linux as well so it is a hardware issue.....2 possibilities;

1) IRQ conflict (new device tries to take old IRQ #)
2) USB controller on my is overloaded (4-5 USB devices, including a IR reciever, webcam w/mic, and G15 keyboard)

Otherwise motherboard is OK so looks like I'll have to learn to live with it instead of fixing the issue. I connected a small, 4 port non powered, USB hub to the front port that will hopefully take some stress of the USB controllers on my motherboard and it seems to be working so far...
