Unable to connect PC to Monitor

[SinerAthin]

Hey guys.

Previous to this, my computer was running fine with the exception of a few bad drivers. I could play games like Rome II on extreme, no problems.

I altered some settings in BIOS while attempting to fix the boot order of my computer.(it was a separate problem where my computer had messed up its boot order)
It was a video/graphic/monitor setting, which I believe I switched to IGP or something. Next reboot, my Computer was unable to detect my screen anymore(which it had done previously just fine).

I attempted to solve this issue by

- Unplugging and reseating RAM.
- Unplugging all cables(including monitor cables)
- Removed any residual energy by pressing the ON button for an extended period of time.
- Removed the GPU
- Removed the CMOS battery

1.5 hour later

Reinserted the CMOS battery & GPU
Plugged in all cables.

My computer runs fine, it starts; but my screen receives no signals.
My fans are blowing, all lights are up & strong on my GPU, Heatsink and Mobo. It gives me the impression that it is running as normal... except with no screen.


I am not sure how to proceed from here. Any advice?

I have attempted to test it on another screen from my friend(one that he is using daily & works fine for him), but my computer doesn't seem to detect it either.
