hmmm sounds like my board problem when i first got my board(asus A8n sli-deluxe) i could have purchased a "pro" version of the same board...the only diffrence?? teh Pro version had heat pipe technology built into the board instead of simply putting a cooling fan on the north bridge and a heat sink onto the south bridge???
the GA-K8N Pro-SLI have firewire unlike the other thats the only diffrence , anyway gigabyte mobos (the recent ones at least) have various issues just read the reviews on newegg and youll see what i mean , i wouldnt take a gigabyte
