Re: USB Problems Biostar A880GZ Motherboard
I have the exact same motherboard and the exact same issue.
Win7 x64 Pro
AMD 8-core FX 8120
8gb DDR3 Gskill Ripjaw
HIS Radeon HD7970
Netgear N300 (WNA3100)
USB randomly fails and all devices refuse to work. Beyond that, my boot locks up if I have my mouse plugged in--it has onboard memory, which the computer then tries to boot from. I can't even get past the boot logo splash--the speaker just makes an endless, shrill beep that makes me long for death.
I have to unplug my mouse anytime I reboot, but once I get to Windows, I can plug it back in and all things run fine. All my games and programs run amazing, but when the computer employs any method of power save mode (monitor off [as I shut off sleep/hibernate]) it's anyone's guess if the USB ports will remain active. I've shut off all power saving modes for the USB ports, flashed bios, tweaked bios, switched jumpers, had a priest bless it, and now I'm checking the internet.
It's good to know someone else is having this issue, as that can be an indicator if we have a reason to turn to the vendor and let them know there may be a series of bad boards. Though, admittedly, I dread the thought of replacing the MoBo off of a fresh build (even with Win7's Out-Of-Box Experience tool).
If there are others with this issue, I'm betting it's a set of poorly soldered boards. We might be out of luck and have to cry warranty to Biostar and see if they can't help us out.
