Did you overclock anything?
If no try cleaning both fans the gpu and the cpu. Dust would build up if you don't clean it every 2 months.

your specs are ok and that psu is a good one and more than enough for your system. even so, make sure power supply fan is spinning and not overheating. also make sure you have replugged the cpu fan header as suggested earlier!
you can even try re installing the gpu. if all fail, remove everything except cpu and one stick of ram and see if you will have a post. if you do, re install all parts one by one to find the possible fault one.

if psu is modular try different cables and make sure your power plug is grounded and mobo properly installed and sitted on the standoffs preventing from shorting out!

check also the meaning of the red light on mobo manual. such sudden fail most probably a psu issue!

Corsair Vengance 2x4gb check them for any burnt pins or if they need further push to securely fit. also as i sead earlier try to post with one ram stick at a time.

you need to remove them and examine them closely. if both appear fine then try posting with one ram stick at a time

Okay ! i've unplugged the ram and replugged at and now the DRAM LED is now off. I restarted my PC and then it started correctly and then the VGA LED light up red and then my PC turned off, and then restarted. And then it went on, the BOOT LED became red and my screen is still saying ''No Signal''

First, the bad news----------------------It sounds as if your Power Supply is (or has) partially failed. That may well have cascaded into other components, but the first step is to replace the Power Supply, then check for other potential failure points (MB, Memory, CPU, HD) and pray for good luck!!

Sounds like its the psu that is causing this.
Try borrowing a friend psu at least 500watts.
If t works correctly that means that you have wrongly connected the cables to the psu or the psu is defective.

note the 500w psu is just for testing if you have to replace the psu you should buy the same 750w one if you want.

yes as i originaly suspected an psu issue. but before you try another one make sure you directly connect a single 6pin pcie cable to the gpu without the use of adapters and check all temps before you lose power.

Did you test the psu? If you are sure that its your gpu then its all upon you.
