I jump my motherboard because i dont have an on and off switch. So that may be doing this but i dont think so. When i jump it everything turns on the cpu fan starts and so do the gpu fans. But after about 5 seconds the gpu fans turn off, so i cannot load the bios. I got it working with just 1 gpu, the bios showed up and everything was on just fine but when i added the other 2 it started to not work. BTW i am setting up a mining rig.
 
Solution
It's possible you are plugged into the wrong GPU and one of the others has become the default display. When I set up a mining rig I set the onboard graphics as default to avoid this issue, is that an option? Otherwise try your monitor on each card to see if it makes a difference. Are you using dummy monitor plugs? it was needed for my rig but I don't remember why exactly.

The GPU fans don't necessarily mean anything, some cards turn the fans off until a certain temperature is reached. Is the CPU fan still spinning?

I tried Litecoin mining for 6 months back when it was a big thing, almost broke even after I resold everything. Decided it was not viable here @ 25c a KW/H
I wish you well but personally I don't think small scale mining at...

I wish you well but personally I don't think small scale mining at home is worthwhile unless you can get very cheap power or get lucky with choosing the right coin at launch. By the time people are buzzing about a particular coin it's generally too late already.

Anyway, you didn't ask my opinion on mining :)

The solution was using onboard video as primary? Something in the motherboard specs that may be helpful

- 5 x PCI-E x1 3.0 Slot (using for bitcoin mining, it is suggested to change to PCI-E 1.0 via BIOS

The solution was changing the video cord to my third gpu where it was outputting video by default.
