Pc does not show BIOS

[kjvnasa]

Hey I was just attempting to try using an nvidea and amd graphics card in one pc and when I out everything back in its original pc and boot it up nothing pops up on any of the screens. 

Here is the link to the forum post that I was attempting to do: http://linustechtips.com/main/topic/303819-mixing-gpus/

 

I have 6 monitors connected at the back and nothing shows up on any of them not even the bios screen. have no idea what happened.

Ok so I can now provide a more detail since yesterday I had no idea what was going on. The pc was turning on and shuting down after approximately 20s. I guessed that something is overheating and crashing and I was right. The intel LGA 775 heat sink was not fully attached to the motherboard. Since my case does not allow me to see the back panel I took out the motherboard and manually made it click. it now does not move at all. The thing is that nothing still shows up on my screen after I power it on. Not even BIOS. I am pretty sure it is not the ram as I have not even taken it out and the whole pc was working before. This is a work computer and I need to figure this out before monday I would really appreciate your help.

Reset your CMOS, if that doesn't work try removing all but one of the GPU's and booting.

Neither of that worked....

I suppose there is a problem with the MOBO. What are my options?
