Red VGA-LED on & no video output

[King-MFS]

Hey guys,
I have recently set up a new rig (about a month ago), and have been working with it nonestop. Yesterday I finished acquiring the results of my simulations, so I decided to run the "5 way Optimization" program given with the motherboard, and then suddenly the screen went black and the VGA-LED turned constant red!! Tried rebooting the system but to no avail. It doesn't provide any video output, but I actually hear the Windows startup with my speakers. What's wrong? What should I do?
Please help me ASAP

System Specs:
1- Motherboard: Asus Maximus VII Hero
2- CPU: Intel core i7 4790
3- GPU: GeForce GTX 760

What kind of monitor do you have? Sounds like your monitor has probably died and is giving you a signal its dead, not the PC

Hey,
Tnx for the answer, but I was able to fix it by:
1- removing the Card
2- Using the on-board graphics to access the bios interface
3- returning the bios features to optimized defaults
It appears that the program I mentioned above changed many attributes in the bios including: DRAM frequency, CPU voltage, GPU voltage, etc.
A word of advice: NEVER use the "5 Way Optimization" program to tweak your board. DO IT MANUALLY!!!
