Fix: AGP hang? try upping the voltage...
 

since I got my GA-7DXR, I've not been able to reset my system w/out pushing the reset button. When the first board ultimately failed, I got it RMA'd and installed the new one. Same problem. I used 2 diff. geforces, 2 psus, 2 nics, and 2 sound cards. No dice.
Just now, I changed a dip switch on the mobo, and upped the AGP voltage from 1.5 to 1.6. Works like a charm. No tech I've spoken with recommended this, so I thought I'd post the fix here...

maybe the board was only supplying like 1.43v when at 1.5v, which won't be enough for the card.

either way, many agp cards seem to love a volt mod. thanks
