Ye, i can get into the "advanced features" menu, but it says in the manual that there is a hidden advanced menu (??? Well, thats what i presume it means???) by pressing CTRL + F1, havn't found it yet...
The only thing i have running on USB is a Alcatel USB DSL Modem, and have had no problems so far... I would of suggested using XP service pack 1, but i see you've already installed it, as they had a few probs with XP with USB beforehand...
Could it your power supply? Maybe if its not powerful enough, too little power is getting through to USB? Though thats only a guess!! Are you using the Dual Power Daughter board for that extra oomph??
I don't know whether its of any relevance, but in SiSoft Sandra i noticed that some of my USB's are USB 1.0 and some are USB 2.0. Could it be that you've got them plugged in to USB 1.0 instead of USB 2.0 . Although i doubt thats the prob, its worth a look...
As to the video, im only running a Geforce 3 :-(
Seems to work fine though...
Another thing i'd consider, is flashing the Bios. As its a new board, they'll be updating it pretty reguarly i would of thought...
Maybe they know about a few probs, and are putting it into a new Bios???
Although im waiting for the dust to settle a while, and updating the Bios probably in about a month or two... If you do update the Bios, be careful if you havn't done it before, although the board does have dual bios, so you should be ok, if it all goes tits up !!!
