OMG!!!! I just bought a new 6150-430 gigabyte mobo from newegg.. (X2 CPU, 7800gtx, 3 gigs patriot ram, the works,) I couldn't get it to display anything on any of the monitors I tried, so after rebuilding it 3 times, I noticed that this time I had left the +12v plug undone, (just this time, It was in the earlier times) so in my anger/stupidity, I plugged it in while the PSU WAS POWERED UP. Sparks. the PSU powers down. Curse, swear, more cursing... sweating, I hit the power button. IT WORKS!!!! I get a post, and am currently half way through installing XP. the only bad part is I can't get the #@*(%&#$ OCZ memory booster to fit into the ram slot, either a capacitor or another mem module is in the way. oh well... major RMA averted. Mission Acomplished.
