Need help figuring out wtf is wrong. PC was left on overnight I come home the TV and monitor still displayed the wallpaper but it was frozen on my comodo popup for a virus. Some keygen is what it was. Anyway shutdown the pc and try to restart. There is no boot to bios. Everything in the pc lights up n all fans are running. I have tried countless times resetting the bios and it just doesn't post. Next I started unplugging all HD sata inputs n any other connections and went to one ram. Removed my sli GPU tried each solo and still no post. I testes CPU and that was ruled out. Couldn't test GPU or PSU but correct me if I'm wrong: my pc was on running and the screen was frozen on HDMI and monitor so I don't think it was PSU or GPU. I am at a loss. Breadboarding still does nothing.

The mobo is 680i Lt sli and when plugged in I see the blue and amber lights suggesting that its not the mobo. Now if it was the GPU or PSU I still should see keyboard post right? Well I do not and I think it is the mobo.

Questions:
1-Would a faulty mobo light up?
2-if the GPU died would both TV n monitor still display a frozen screen?
3-if the PSU or mobo malfunctioned would the pc still remain running with a frozen screen?
4-is it possible to hack bios and cause my situaiton?
5-any suggestions on what to test next?

Thanks in advance for responses
