Yeah, that could be an good option but i have checked the setup for several times...
another usb port, an hole new usb-pci card instead of the onboard usb, etc..
My windows power system is always on performance, even all the bios settings are high (cool-fan, etc)
it seems that amd has some troubles with the acpi in the bios with some usb controllers.. maybe that's the reason..
I think i'm going to try my other pc, to look of this happens on that also..
i let you know!
thanks
