When you get the C1 error, try this.....

-Turn off and unplug PSU
-move jumper J1 from 1-2 to 2-3 and wait maybe 10 sec..
-move the jumper back to original pos. and turn your system back on....

or

-Turn off and unplug PSU
-clear cmos and the jumper right beside it, then take off the batt.; wait a few
-replace batt and both jumpers and thy to boot...

Hope this helps cos thats the only hting thats getting me going these days using my QX9650....

I swear running DFI boards is like having a really hot girlfriend thats a total b!tch....
