Have you tried toning down your OC? Maybe run at stock speed for a bit? I would definitely focus on your RAM.

I cant get past the 3 the lights and to date i've tried 3 sets of ram 2 known good

i'm wondering if it could be a slot prob?

Try tuning your computer down to stock settings (optimized defaults) first.

 

Then try with one stick in slot 2 and see. How high voltage are U runing?

 

We need some more input to troublshoot U.

Power your PC off. Unplug it. Remove the CMOS battery and leave it out for 15 minutes. Before you put the battery back in, remove one stick of memory from the board (make sure only one stick is plugged in) Put the battery back in and plug in your pc. Turn it back on and voila.... or not. Good luck!

pull one vid card and one stick of ram (leaving a stick in the orange slot closest to the edge of the board)

 

try powering up

 

if that doesnt work, pull the top vid card (closest to cpu) and leave the bottom vid card and try powering up with a single stick of RAM (always clearing cmos for at least 30 seconds between each attempt)

 

if that doesn't work, reset your SLI jumpers back to original (single card) and use the bottom PCI-E vid card and a single stick of RAM

 

(ie: try all combinations...I had to fight one of these one day that got sorta messed up in SLI mode and it took a different vid card + fooling with the SLI jumpers and using the second PCI-E slot to get it all back on track, then it all went back together in SLI mode etc after getting the bios flashed to 5/10-2)
