Ga p67A-UD7-B3 - Power Problems

[Randhart]

Hi there,

I recently tried to replace my display cards, got two GTX680's and installed them, powered the system down, and and switched the power supply off.  Upon finalizing the installation I went to switch the power back on but there was no power to the MB... the lights that used to come on didn't  and trying the power button (chassis and MB) nothing happened.

I checked the Power Supply but all the rails were fine, I also disconnected everything apart from RAM, CPU and one of the original Display cards but still nothing.  I have since replaced the P67A my old MB and it is working fine.  I've looked the MB over and can't visually see any damage to the MB also can't smell any evidence of anything that may have burnt.

I have since tried the motherboard with a different power supply (a new Corsair model) and yet still no power seems to be going to the MB.

I think I have exhausted my options... is there anything I can do or is the board dead? which would be sad because I like it very much!!

System:
GA P67A-UD7-B3
i7 2600K
8GB DDR3 RAM
OCZ 850W PSU (also tried Corsair CX600M)
Twin EVGA GTX 680 FTW display cards
OCZ Vertex3 SDD
Twin WD 1TB HDD

I have seen where a MB would crash like that and for some reason it would lockup.

Now I'm not say this will work but pull the cmos battery set the jump on the the cmos to clear the cmos.

Let it sit for a couple hours and than put put the battery back in and reset the jumper.

Thanyou Soooo much... that squared it right away... the CMOS clear didnt quite work but the battery out cleared it right up.. It's all back up and running Beautifully!!

Nice to hear everything work out. Like I said that was a shot in the dark.

I had a Abit board do the same thing. But it was a PSU that had gone bad.

That did the same thing lockup the MB.
