    DP35DP 0572 boot issue, can't downgrade


      I bought a q9550 today and stupid me upgraded my bios from 04xx I can't remember but it was 0484 which was hte minimum for q9550 support.


      anyhow i upgraded to 0572 and results is the strangest problem. With PC off, from a cold start. it would just hang, doesn't even post. turn it off via holding down teh power button then power it again before I can get it to post and off to windows.


      I've attempted to downgrade to 0484 and start from there but I have no luck.


      I've tried the USB and CD method I get absolutely no video. USB drive is never accessed neither is teh CD.


      any help would be appreciated.
